See [`all(iterable)`][1] :

&gt; Return `True` if all elements of the
&gt; *iterable* are true (or if the *iterable*
&gt; is empty).

And [`any(iterable)`][2] :

&gt; Return `True` if any element of the
&gt; *iterable* is true. If the *iterable* is empty, return `False`.

  [1]: http://docs.python.org/library/functions.html#all
  [2]: http://docs.python.org/library/functions.html#any

The best way to do it is with the `any()` and `all()` functions.

    vals = [True, False, True, True, True]
    if any(vals):
       print &quot;any() reckons there&#39;s something true in the list.&quot;
    if all(vals):
       print &quot;all() reckons there&#39;s no non-True values in the list.&quot;
    if any(x % 4 for x in range(100)):
       print &quot;One of the numbers between 0 and 99 is divisible by 4.&quot;

For example, can I take this script ([from mozilla tutorial][1]):

    &lt;html&gt;
     &lt;head&gt;
      &lt;script type=&quot;application/javascript&quot;&gt;
        function draw() {
          var canvas = document.getElementById(&quot;canvas&quot;);
          if (canvas.getContext) {
            var ctx = canvas.getContext(&quot;2d&quot;);
    
            ctx.fillStyle = &quot;rgb(200,0,0)&quot;;
            ctx.fillRect (10, 10, 55, 50);
    
            ctx.fillStyle = &quot;rgba(0, 0, 200, 0.5)&quot;;
            ctx.fillRect (30, 30, 55, 50);
          }
        }
      &lt;/script&gt;
     &lt;/head&gt;
     &lt;body onload=&quot;draw();&quot;&gt;
       &lt;canvas id=&quot;canvas&quot; width=&quot;150&quot; height=&quot;150&quot;&gt;&lt;/canvas&gt;
     &lt;/body&gt;
    &lt;/html&gt;

and mix this JavaScript with jQuery&#39;s document.ready instead of relying on onload?

I have two tables, keywords and data. 

Table keywords have 2 columns (id, keyword), table data have 3 columns (id[foreign key of keywords.id], name, value).

I am using this query:

    SELECT k.id, d.value, d.name
    FROM keywords AS k
    INNER JOIN data as d ON k.id = d.id

it returns something like:

    1 123 name1
    1 456 name2
    2 943 name1
    3 542 name1
    3 532 name2
    3 682 name3

Each id can have values from 0 to 3 (maybe more in the future).

How can I retrieve all the rows with the same id in the same row?

Like

    1 123 456
    2 943
    3 542 532 682

I want to do this because I want to be able to sort the values.

How to group mysql rows with same column value into one row?

I have a list of booleans I&#39;d like to logically combine using and/or.  The expanded operations would be:

    vals = [True, False, True, True, True, False]

    # And-ing them together
    result = True
    for item in vals:
        result = result and item

    # Or-ing them together
    result = False
    for item in vals:
        result = result or item

Are there nifty one-liners for each of the above?

I&#39;m working on making a URL shortener for my site, and my current plan (I&#39;m open to suggestions) is to use a node ID to generate the shortened URL. So, in theory, node 26 might be `short.com/z`, node 1 might be `short.com/a`, node 52 might be `short.com/Z`, and node 104 might be `short.com/ZZ`. When a user goes to that URL, I need to reverse the process (obviously).

I can think of some kludgy ways to go about this, but I&#39;m guessing there are better ones. Any suggestions?

Can someone please explain?

I have a matplotlib figure which I am plotting data that is always referred to as nanoseconds (1e-9).  On the y-axis, if I have data that is tens of nanoseconds, ie. 44e-9, the value on the axis shows as 4.4 with a +1e-8 as an offset.  Is there anyway to force the axis to show 44 with a +1e-9 offset?

The same goes for my x-axis where the axis is showing +5.54478e4, where I would rather it show an offset of +55447 (whole number, no decimal - the value here is in days).

I&#39;ve tried a couple things like this:

    p = axes.plot(x,y)
    p.ticklabel_format(style=&#39;plain&#39;)


for the x-axis, but this doesn&#39;t work, though I&#39;m probably using it incorrectly or misinterpreting something from the docs, can someone point me in the correct direction?

Thanks,
Jonathan

![Problem illustration][1]

------
I tried doing something with formatters but haven&#39;t found any solution yet...:

    myyfmt = ScalarFormatter(useOffset=True)
    myyfmt._set_offset(1e9)
    axes.get_yaxis().set_major_formatter(myyfmt)
and

    myxfmt = ScalarFormatter(useOffset=True)
    myxfmt.set_portlimits((-9,5))
    axes.get_xaxis().set_major_formatter(myxfmt)

On a side note, I&#39;m actually confused as to where the &#39;offset number&#39; object actually resides...is it part of the major/minor ticks?

I have two lists, **the first of which is guaranteed to contain exactly one more item than the second**. I would like to know the most Pythonic way to create a new list whose even-index values come from the first list and whose odd-index values come from the second list.

    # example inputs
    list1 = [&#39;f&#39;, &#39;o&#39;, &#39;o&#39;]
    list2 = [&#39;hello&#39;, &#39;world&#39;]
    
    # desired output
    [&#39;f&#39;, &#39;hello&#39;, &#39;o&#39;, &#39;world&#39;, &#39;o&#39;]

This works, but isn&#39;t pretty:

    list3 = []
    while True:
        try:
            list3.append(list1.pop(0))
            list3.append(list2.pop(0))
        except IndexError:
            break

How else can this be achieved? What&#39;s the most Pythonic approach?

How to compare two lists in python?

    date = &quot;Thu Sep 16 13:14:15 CDT 2010&quot;

    dateArr = [] dateArr = date.split() 
    sdateArr = [] sdateArr = sdate.split() 

Now I want to compare these two lists. I guess split returns a list. We can do simple comparision in Java like `dateArr[i] == sdateArr[i]`, but how can we do it in Python?

Using C# what is the best way to sort a List numerically?
my list has items 5,7,3 and I would like them sorted 3,5,7.  I know some longer ways, but I would imagine linq has a quicker way?

Sorting a List&lt;int&gt;

I am generating multi-series graphs with the date along the X-Axis.  

The problem is that not all of the series in the graph have the same dates in the date range.  Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range.  

This skews the charts I need to create.  Go, given the date range taken at the begining of the query I&#39;d like to generate a list of dates and populate the data to be graphed, padding those series with 0&#39;s for those dates that have no data.

Given two lists:

    x = [1,2,3]
    y = [4,5,6]

What is the syntax to:

 1. Insert `x` into `y` such that `y` now looks like `[1, 2, 3, [4, 5, 6]]`?
 2. Insert all the items of `x` into `y` such that `y` now looks like `[1, 2, 3, 4, 5, 6]`?

I&#39;m submitting a parameter `show_all` with the value `true`. This value isn&#39;t associated with a model.

My controller is assigning this parameter to an instance variable:

    @show_all = params[:show_all]

However, `@show_all.is_a? String`, and `if @show_all == true` always fails.
