Is it a native promise error? What does it imply? Google shows no result found.

What does this error mean — Uncaught TypeError: Already read?

I am using this function to uncompress the body or a HTTP response if it is compressed with gzip, compress or deflate. 

    def uncompress_body(self, compression_type, body):
        if compression_type == &#39;gzip&#39; or compression_type == &#39;compress&#39;:
            return zlib.decompress(body)
        elif compression_type == &#39;deflate&#39;:
            compressor = zlib.compressobj(9, zlib.DEFLATED, -zlib.MAX_WBITS)
            compressed = compressor.compress(body)
            compressed += compressor.flush()
            return base64.b64encode(compressed)

        return body

However python throws this error message.

    TypeError: a bytes-like object is required, not &#39;_io.BytesIO&#39;
on this line:

    return zlib.decompress(body)

Essentially, how do I convert from &#39;_io.BytesIO&#39; to a bytes-like object?

I have some JavaScript code that gives this error

```none

So, I have this code:

    url = &#39;http://google.com&#39;
    linkregex = re.compile(&#39;&lt;a\s*href=[\&#39;|&quot;](.*?)[\&#39;&quot;].*?&gt;&#39;)
    m = urllib.request.urlopen(url)
    msg = m.read()
    links = linkregex.findall(msg)


But then python returns this error:

    links = linkregex.findall(msg)

What did I do wrong?

Following is my code:

    test = &#39;abc&#39;
    if True:
        raise test + &#39;def&#39;

And when i run this, it gives me the `TypeError`
    
    TypeError: exceptions must be old-style classes or derived from BaseException, not str

So what kind of type should the `test` be?

**Background**: I am writing a python program which should manage my music files. It crawls directories and puts the files and their meta data (via mutagen), encoded in JSON, in a file as a simple &quot;database&quot;. I have the directory searching fine, but when I try and save the database, or encode to JSON, it throws a &quot;TypeError: {...} is not JSON serializable&quot;
(the ... are some keys and values from a dict, more on that below)

**The Problem**: The program builds a large dictionary object following this format:

    {
        &quot;&lt;song id&gt;&quot;:{
            &quot;artist&quot;:&quot;&lt;song artist&gt;&quot;,
            &quot;album&quot;:&quot;&lt;song album&gt;&quot;,
            &quot;title&quot;:&quot;&lt;song title&gt;&quot;},
        ...
    }

Every single song file is indexed via this format. When I try to dump the database to a file, I get this:

    Traceback (most recent call last):
      File &quot;&lt;pyshell#2&gt;&quot;, line 1, in &lt;module&gt;
        sit()
      File &quot;D:\workbench\ideas\musicmanager\v0\spider.py&quot;, line 116, in sit
        json.dump(js.db,f,True)
      File &quot;C:\Python27\lib\json\__init__.py&quot;, line 181, in dump
        for chunk in iterable:
      File &quot;C:\Python27\lib\json\encoder.py&quot;, line 428, in _iterencode
        for chunk in _iterencode_dict(o, _current_indent_level):
      File &quot;C:\Python27\lib\json\encoder.py&quot;, line 402, in _iterencode_dict
        for chunk in chunks:
      File &quot;C:\Python27\lib\json\encoder.py&quot;, line 402, in _iterencode_dict

        o = _default(o)
      File &quot;C:\Python27\lib\json\encoder.py&quot;, line 178, in default
        raise TypeError(repr(o) + &quot; is not JSON serializable&quot;)
    TypeError: {&#39;album&#39;: [u&quot;Rooney&#39;s Lost Album&quot;], &#39;title&#39;: [u&#39;The Kids
    After Sunset&#39;], &#39;artist&#39;: [u&#39;Rooney&#39;]} is not JSON serializable

With the key for that particular song entry being

    Rooney|Rooney&#39;s Lost Album|The Kids After Sunset|The Kids After Sunset.itunes.mp3

(the format for the id is a little bulky, I might end up hashing that...)

So I tried to

    json.dumps({&#39;album&#39;: [u&quot;Rooney&#39;s Lost Album&quot;], &#39;title&#39;: [u&#39;The Kids
    After Sunset&#39;], &#39;artist&#39;: [u&#39;Rooney&#39;]})

which worked fine, as did

    json.dumps({&quot;Rooney|Rooney&#39;s Lost Album|The Kids After Sunset|The Kids
    After Sunset.itunes.mp3&quot;:&quot;&quot;})

And then I tried this:

    rooney = &quot;Rooney|Rooney&#39;s Lost Album|The Kids After Sunset|The Kids
        After Sunset.itunes.mp3&quot;
    json.dumps({rooney:js.db[&#39;songsbyid&#39;][rooney]})

Which failed with the type error again.

Why does that object fail with json.dump? I have plenty of other objects with keys containing pipes &quot;|&quot; and apostrophes &quot;&#39;&quot;... At the moment, I have no way for anyone else to test this, should I post a pickled version of the database object?

**Additional Notes**

 - The resulting object below json.dumps is fine, so I am wondering if the issue has to do with the size of the database in any way?

    &gt;&gt;&gt; {rooney:js.db[&#39;songsbyid&#39;][rooney]}
    {&quot;Rooney|Rooney&#39;s Lost Album|The Kids After Sunset|The Kids
    After Sunset.itunes.mp3&quot;: {&#39;album&#39;: [u&quot;Rooney&#39;s Lost Album&quot;],
    &#39;title&#39;: [u&#39;The Kids After Sunset&#39;], &#39;artist&#39;: [u&#39;Rooney&#39;]}}

 - If I exclude the song by renaming the extension so the script ignores it, another arbitrary song causes the same error. I renamed&amp;excluded this new song, and ran into ANOTHER new song... I don&#39;t know how many there are.

 - I changed my program to crawl the next furthest sub-directory containing the original problem song, and json.dump raised a TypeError on a completely different song...






json.dump throwing &quot;TypeError: {...} is not JSON serializable&quot; on seemingly valid object?

The program is supposed to take in two names, and if they are the same length it should check if they are the same word.  If it&#39;s the same word it will print *&quot;The names are the same&quot;*. If they are the same length but with different letters it will print *&quot;The names are different but the same length&quot;*. The part I&#39;m having a problem with is in the bottom 4 lines.
 

    #!/usr/bin/env python
    # Enter your code for &quot;What&#39;s In (The Length Of) A Name?&quot; here.
    name1 = input(&quot;Enter name 1: &quot;)
    name2 = input(&quot;Enter name 2: &quot;)
    len(name1)
    len(name2)
    if len(name1) == len(name2):
	    if name1 == name2:
	        print (&quot;The names are the same&quot;)
	    else:
	        print (&quot;The names are different, but are the same length&quot;)
        if len(name1) &gt; len(name2):
	        print (&quot;&#39;{0}&#39; is longer than &#39;{1}&#39;&quot;% name1, name2)
        elif len(name1) &lt; len(name2):
	        print (&quot;&#39;{0}&#39;is longer than &#39;{1}&#39;&quot;% name2, name1)

When I run this code it displays:

    Traceback (most recent call last):

Everything works fine when I wrote the js logic in a closure as a single js file, as:

    (function(win){
       //main logic here
       win.expose1 = ....
       win.expose2 = ....
    })(window)

but when I try to insert a logging alternative function before that closure in the same js file, 

     window.Glog = function(msg){
         console.log(msg)
     }
     // this was added before the main closure.

     (function(win){
       //the former closure that contains the main javascript logic;
     })(window)

it complains that there is a TypeError:

I am trying to send a simple dictionary to a json file from python, but I keep getting the &quot;TypeError: 1425 is not JSON serializable&quot; message.

    import json
    alerts = {&#39;upper&#39;:[1425],&#39;lower&#39;:[576],&#39;level&#39;:[2],&#39;datetime&#39;:[&#39;2012-08-08 15:30&#39;]}
    afile = open(&#39;test.json&#39;,&#39;w&#39;)
    afile.write(json.dumps(alerts,encoding=&#39;UTF-8&#39;))
    afile.close()

If I add the default argument, then it writes, but the integer values are written to the json file as strings, which is undesirable.

    afile.write(json.dumps(alerts,encoding=&#39;UTF-8&#39;,default=str))

I keep getting a `TypeError: unhashable type: &#39;list&#39;`. I know that keys in a dictionary can&#39;t be lists but I&#39;m trying to make my value into a list not the key. I&#39;m wondering if I made a mistake somewhere.

I am defining an object like this:

    function Project(Attributes, ProjectWidth, ProjectHeight) {
    	this.ProjectHeight = ProjectHeight;
    	this.ProjectWidth = ProjectWidth;
    	this.ProjectScale = this.GetProjectScale();

    	this.currentLayout = &#39;&#39;;
    
    	this.CreateLayoutArray = function()

I then try to create an instance like this:

    var newProj = new Project(a,b,c);

but this exception is thrown:

    Project is not a constructor

What could be wrong? I googled around a lot, but I still can&#39;t figure out what I am doing wrong.




Javascript &quot;Not a Constructor&quot; Exception while creating objects

Perhaps I&#39;ve fallen victim to misinformation on the web, but I think it&#39;s more likely just that I&#39;ve misunderstood something.  Based on what I&#39;ve learned so far, range() is a generator, and generators can be used as iterators.  However, this code:

    myrange = range(10)
    print(next(myrange))
gives me this error:

    TypeError: &#39;range&#39; object is not an iterator
What am I missing here?  I was expecting this to print 0, and to advance to the next value in `myrange`.  I&#39;m new to Python, so please accept my apologies for the rather basic question, but I couldn&#39;t find a good explanation anywhere else.

If range() is a generator in Python 3.3, why can I not call next() on a range?

There is a similar question on StackOverflow: https://stackoverflow.com/questions/489269/python-super-raises-typeerror-why, where the error is explained by the fact that the user class is not a new-style class.  However, the class above is a new-style class, as it inherits from `object`:

    &gt;&gt;&gt; isinstance(HTMLParser(), object)
    True

What am I missing? How can I use `super()`, here?

Using `HTMLParser.__init__(self)` instead of `super(TextParser, self).__init__()` would work, but I would like to understand the TypeError.

PS: Joachim pointed out that being a new-style-class instance is not equivalent to being an `object`. I read the opposite many times, hence my confusion (example of new-style class instance test based on `object` instance test: https://stackoverflow.com/revisions/2655651/3).

So in this case, the output should be all rows in the DataFrame having `CHUNK_NAME=&#39;300_321&#39;` and `LAMBDA=lambda1`. There would be n rows one for each `beta` value that would be returned. But instead I get the following error. Any help in solving this problem would be appreciated.

    TypeError: cannot compare a dtyped [float64] array with a scalar of type [bool]



pandas comparison raises TypeError: cannot compare a dtyped [float64] array with a scalar of type [bool]

I have the following code 

    import nltk, os, json, csv, string, cPickle
    from scipy.stats import scoreatpercentile

    lmtzr = nltk.stem.wordnet.WordNetLemmatizer()

    def sanitize(wordList): 
	answer = [word.translate(None, string.punctuation) for word in wordList] 
	answer = [lmtzr.lemmatize(word.lower()) for word in answer]
	return answer

    words = []
    for filename in json_list:
		words.extend([sanitize(nltk.word_tokenize(&#39; &#39;.join([tweet[&#39;text&#39;] 
                       for tweet in json.load(open(filename,READ))])))])

I&#39;ve tested lines 2-4 in a separate testing.py file when I wrote
    
    import nltk, os, json, csv, string, cPickle
    from scipy.stats import scoreatpercentile

    wordList= [&#39;\&#39;the&#39;, &#39;the&#39;, &#39;&quot;the&#39;]
    print wordList
    wordList2 = [word.translate(None, string.punctuation) for word in wordList]
    print wordList2
    answer = [lmtzr.lemmatize(word.lower()) for word in wordList2]
    print answer

    freq = nltk.FreqDist(wordList2)
    print freq

and the command prompt returns [&#39;the&#39;,&#39;the&#39;,&#39;the&#39;], which is what I wanted (removing punctuation).

However, when I put the exact same code in a different file, python returns a TypeError stating that

    File &quot;foo.py&quot;, line 8, in &lt;module&gt;
      for tweet in json.load(open(filename, READ))])))])
    File &quot;foo.py&quot;, line 2, in sanitize
      answer = [word.translate(None, string.punctuation) for word in wordList]
    TypeError: translate() takes exactly one argument (2 given)

json_list is a list of all the file paths (I printed and check that this list is valid). I&#39;m confused on this TypeError because everything works perfectly fine when I&#39;m just testing it in a different file.

I don&#39;t understand why I can&#39;t use my variable `c`.

code:

    from turtle import *
    
    speed(0)
    hideturtle()
    c = 450
    
    def grid(x,y,a):
        seth(0)
        pu()
        goto(x,y)
        pd()
        for i in range(4):
            forward(a)
            rt(90)
        for i in range(c/10):
            seth(0)
            forward(10)
            rt(90)
            forward(c)
            backward(c)
        for i in range(c/10):
            seth(0)
            rt(90)
            forward(10)
            rt(90)
            forward(c)
            backward(c)
        pu()
        goto(a+10,0)
        write(&quot;x&quot;)
        goto(0,a+10)
        write(&quot;y&quot;)
        pd()
        
    grid(0,0,c)
    grid(-c,0,c)
    grid(-c,c,c)
    grid(0,c,c)


I get the following error message:
