You want to find the median of a list?

Assuming Apache's setup, you (should) just need to:
1. put it in your cgi-bin (or sub-directory)
2. change the extension to .cgi,
3. make it executable and voila!Leave a comment:

Neat trick, but Python101 is looking for a method of counting items common to both lists....Leave a comment:

How about this:
[code=python]
count=0
for a in A:
if a in B: count+=1
print count
[/code]
or this:
[code=python]
count=sum([1 for a in A if a in B])
print count
[/code]Leave a comment:

It will work if you "map" the network share.

Here a "batteries included" approach using numpy and pylab

Nothing built-in.
Popular choices are gnuplot, and matplotlib.
If you have matlab experience try matplotlib. The syntax and concepts are similiar.Leave a comment:

And another... with re.
It had to be done!
Code:import re def repl(match): globals()['count']+=1 return '$%i%s'%(globals()['count'], match.groups()[0]) globals()['count']=0 print re.sub('(AS)',repl,stringA) >>> $1ASD DSA D$2ASFSADSA FSAFSADSAF $3ASLeave a comment:

Excel has excellent CSV (comma separated values) support and the Python CSV module is standard and pretty easy to use. It might also make your code easier to modify. With your code if you want to insert an entry into column 3 for example you would have to swap a lot of stuff around.

Capture Numpy errors and warnings
How can I capture Numpy errors and warnings (to a log file for instance)? I tried redirecting stdout and stderr with:
but Numpy warnings are not caught and are passed to the shell.Code:import sys sys.stdout=sys.stderr=open('log.log','wb')
I am using 2.4.4 and numpy 1.0.3.1 on a windows XP box.
Thanks,

The method described above works for Python 2.5 but not for 2.4.4. Operator.itemge tter only accepts one argument under 2.4.4. Another problem I found was that with 2.5 the * will only flatten a sequence. So if you want to sort by unordered a set of unordered indices (e.g. -1, 4,5,6) your out of luck (from want I tried at least).
I ended writing a function which works with 2.4 and 2.5. I am posting it here encase someone runs into the...Leave a comment:

operator.itemgetter() syntax
Hi all,
I need to pass operator.itemge tter(item,...) multiple arguments but the number of arguments is variable.
...Code:ivlist=['var1','var2','var3'] # This variable changes length keyindices=range(-len(ivlist)-1,0) # = [-4, -3, -2, -1] in this example # What I want in this example is M_keys=M.keys() for key in sorted(M_keys,key=operator.itemgetter(-4, -3, -2, -1)): # for
