Format numbers

Just screwing around making up practice problems. I can't get the format right. I am trying to learn how to get a output line to line up neatly. import random lo=1 hi=1 # I am adding or subtracting 0s from this input number fm=len(str(hi)) # This counts the digits of the input number print f

What meaning is 'a[0:10:2]'?

hi, When I learn slice, I have a new question on the help file. If I set: pp=a[0:10:2] pp is array([1, 3]) I don't know how a[0:10:2] gives array([1, 3]). I know matlab a lot, but here it seems quite different. Could you tell me what meaning a[0:10:2] is? Thanks, class slice(object) | s

Re: What meaning is of '#!python'?
