Yes, there is [`urlparse.urljoin`][1], or [`urllib.parse.urljoin`][2] for Python 3.

    &gt;&gt;&gt; try: from urlparse import urljoin # Python2
    ... except ImportError: from urllib.parse import urljoin # Python3
    ...
    &gt;&gt;&gt; urljoin(&quot;http://www.asite.com/folder/currentpage.html&quot;, &quot;anotherpage.html&quot;)
    &#39;http://www.asite.com/folder/anotherpage.html&#39;
    &gt;&gt;&gt; urljoin(&quot;http://www.asite.com/folder/currentpage.html&quot;, &quot;folder2/anotherpage.html&quot;)
    &#39;http://www.asite.com/folder/folder2/anotherpage.html&#39;
    &gt;&gt;&gt; urljoin(&quot;http://www.asite.com/folder/currentpage.html&quot;, &quot;/folder3/anotherpage.html&quot;)
    &#39;http://www.asite.com/folder3/anotherpage.html&#39;
    &gt;&gt;&gt; urljoin(&quot;http://www.asite.com/folder/currentpage.html&quot;, &quot;../finalpage.html&quot;)
    &#39;http://www.asite.com/finalpage.html&#39;
   
for copy-and-paste:

    try:
        from urlparse import urljoin  # Python2
    except ImportError:
        from urllib.parse import urljoin  # Python3

  [1]: https://docs.python.org/2/library/urlparse.html#urlparse.urljoin
  [2]: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urljoin

You can also call the `urljoin` function through Python&#39;s `requests` library.

This code:

    import requests
    
    requests.compat.urljoin(&#39;http://example.com/foo.html&#39;, &#39;bar.html&#39;)

Will return a value of `http://example.com/bar.html`

Can someone explained, as detailed as possible, the differences between the following types?

    List
    List&lt;Object&gt;
    List&lt;?&gt;

Let me make this more specific. When would I want to use

    // 1 
    public void CanYouGiveMeAnAnswer(List l) { }

    // 2
    public void CanYouGiveMeAnAnswer(List&lt;Object&gt; l) { }

    // 3
    public void CanYouGiveMeAnAnswer(List&lt;?&gt; l) { }

Java Generics: List, List&lt;Object&gt;, List&lt;?&gt;

I have an ASP.NET MVC project containing an AdminController class and giving me URls like these:

&gt;   http://example.com/admin/AddCustomer
&gt;
&gt;    http://examle.com/Admin/ListCustomers

I want to configure the server/app so that URIs containing **/Admin** are only accessible from the 192.168.0.0/24 network (i.e. our LAN)

I&#39;d like to restrict this controller to only be accessible from certain IP addresses.

Under WebForms, /admin/ was a physical folder that I could restrict in IIS... but with MVC, of course, there&#39;s no physical folder. Is this achievable using web.config or attributes, or do I need to intercept the HTTP request to achieve this?

I&#39;ve discovered a new pattern.  Is this pattern well known or what is the opinion about it?

Basically, I have a hard time scrubbing up and down source files to figure out what module imports are available and so forth, so now, instead of

    import foo
    from bar.baz import quux
    
    def myFunction():
        foo.this.that(quux)

I move all my imports into the function where they&#39;re actually used., like this:

    def myFunction():
        import foo
        from bar.baz import quux
    
        foo.this.that(quux)

This does a few things.  First, I rarely accidentally pollute my modules with the contents of other modules.  I could set the `__all__` variable for the module, but then I&#39;d have to update it as the module evolves, and that doesn&#39;t help the namespace pollution for code that actually lives in the module.

Second, I rarely end up with a litany of imports at the top of my modules, half or more of which I no longer need because I&#39;ve refactored it.  Finally, I find this pattern MUCH easier to read, since every referenced name is right there in the function body.

Is there a way to step between 0 and 1 by 0.1? 

I thought I could do it like the following, but it failed:

    for i in range(0, 1, 0.1):
        print(i)

Instead, it says that the step argument cannot be zero, which I did not expect.

Given a list of strings, I want to sort it alphabetically and remove duplicates. I know I can do this:

    from sets import Set
    [...]
    myHash = Set(myList)

but I don&#39;t know how to retrieve the list members from the hash in alphabetical order.

I&#39;m not married to the hash, so any way to accomplish this will work. Also, performance is not an issue, so I&#39;d prefer a solution that is expressed in code clearly to a fast but more opaque one.


How to sort and remove duplicates from Python list?

I know of `@staticmethod`, `@classmethod`, and `@property`, but only through scattered documentation. What are all the function decorators that are built into Python? Is that in the docs? Is there an up-to-date list maintained somewhere?

Python - what are all the built-in decorators?

Is there a built-in that removes duplicates from list in Python, whilst preserving order? I know that I can use a set to remove duplicates, but that destroys the original order. I also know that I can roll my own like this:

    def uniq(input):
      output = []
      for x in input:
        if x not in output:
          output.append(x)
      return output

(Thanks to [unwind][1] for that [code sample][2].)

But I&#39;d like to avail myself of a built-in or a more Pythonic idiom if possible.

In a web application that makes use of AJAX calls, I need to submit a request but add a parameter to the end of the URL, for example:

Original URL: 
&gt; http://server/myapp.php?id=10

Resulting URL:
&gt; http://server/myapp.php?id=10**&amp;enabled=true**

Looking for a JavaScript function which parses the URL looking at each parameter, then adds the new parameter or updates the value if one already exists.

Adding a parameter to the URL with JavaScript

Is a URI (specifically an HTTP URL) allowed to contain one or more space characters? If a URL *must* be encoded, is `+` just a commonly followed convention, or a legitimate alternative?  

In particular, can someone point to an RFC that indicates that a URL with a space *must* be encoded?

**Motivation for question:** While beta-testing a web site, I noted that some URLs were constructed with spaces in them. Firefox seemed to do the right thing, which surprised me! But I wanted to be able to point the developers to an RFC so that they would feel the need to fix those URLs.

Is a URL allowed to contain a space?

If I had a URL such as

    http://localhost/search.php?year=2008

How would I write a JavaScript function to grab the variable *year* and see if it contains anything?

I know it can be done with `location.search` but I can’t figure out how it grabs parameters.

How can I get a specific parameter from location.search?

I am using a `ListView` to display some images and captions associated with those images. I am getting the images from the Internet. Is there a way to lazy load images so while the text displays, the UI is not blocked and images are displayed as they are downloaded? 

The total number of images is not fixed.

I have two paths: 

    fred\frog
and
 
    ..\frag

I can join them together in PowerShell like this:

    join-path &#39;fred\frog&#39; &#39;..\frag&#39;

That gives me this:

    fred\frog\..\frag

But I don&#39;t want that. I want a normalized path without the double dots, like this:

    fred\frag

How can I get that?

When importing a project into eclipse, it somehow started creating recursive versions of the directory. 

Now, when I try to delete anything, I get the message &quot; the file name you specify is too long.&quot;

I can&#39;t delete it from the command shell. I can&#39;t delete it from explorer. I can&#39;t do ANYTHING with it. I have no idea how many copies of it Eclipse created. Eclipse was running for like a minute before I realized something was wrong and I cancelled the operation. 

I can get the properties of the top level folder, and it says it contains 497 folders.
