The following code:
def functions():
l=list()
for i in range(5):
def inner():
return i
l.append(inner)
return l
print [f() for f in functions()]
returns [4,4,4,4,4], rather than the hoped for [0,1,2,3,4]. I presume
this is something to do with the variable i getting re-bound every time
we go through the loop, or something, but I'm not sure how to fix this.
I've found the ability in python to create functions on the fly and
store and index them for later use incredibly powerful, so it'd be nice
to get past this little roadblock.
