I have a list with some values being NaN (after division-by-zero). How
can I
check and remove all the NaN values?
NaN is, so far as I know, a JavaScript only feature. The equivalent thing
in Python would be to avoid having those 'values' in your list in the first
place
by trapping the divide by zero error while creating your list, or by not
dividing by zero in the first place:
mylist = []
for item in biglist:
try: value = item/divisor
except ZeroDivisionError: continue # ignore if divide by zero
mylist.append(value)
OR
mylist = [item/divisor for item in biglist if divisor != 0] # avoids the
division
If you can't do either of those then we need a bit more information about
how the "NaN"s come about.
