Okay, I give up. What's the best way to count number of items in a list?
For instance, a=[[1,2,4],4,5,[2,3]] I want to know how many items are there in a (answer should be 7 - I don't want it to be 4) I tried: b=len([x for y in a for x in y]) That doesn't work because you would get an iteration over non-sequence. I tried: g=lambda x: (1,len(x))[isinstance(x,(list,tuple,dict))] b=sum(lambda(x) for x in a) and that didn't work because I get a TypeError from the len function (don't know why) I can, of course: i=0 for x in a: if isinstance(x,(list,tuple,dict)): i += len(x) else: i += 1 but that's so C-like...
