I'm not sure if you can or want to do this solely one list comprehension.
You could make a helper function and use map:
###
def helper(i):
i.pop(3)
return map(int, i)
a = map(helper, x)
###
Description of map:
http://docs.python.org/lib/built-in-funcs.html
I think map is a little cleaner is some cases. Not sure if its more Pythonic,
I'm still trying to figure out exactly what that
means.
The need to pop(3) off the list makes a pure functional solution kinda hard.
Thanks,
Ryan

Subject: [Tutor] List comprehensions
Hi,
Is there a way to apply multiple actions within one list comprehension?
i.e. instead of
a = []
for i in x:
i.pop(3)
g = [ int(item) for item in i]
a.append(g)
Is there any guides to this (possibly obtuse) tool?
Regards,
Liam Clarke
PS I can see how nested list comprehensions can quickly lose readability.
