Hi there,
I'm trying to use List in a function. But it doesn't work. Here are sample code
not work: ---------------------------------------def getResult(): ls = []
ls= ls.append(100) ls= ls.append(200) return ls
reList = []reList = getResult()lsLength = len(reList)print '\n The length of
the list is:' + str(lsLength)-----------------------------------------I ran the
above code, there is an error message: AttributeError: 'NoneType' object has no
attribute 'append'
But the code below not using list in a function
works.----------------------------------------------### This works:ls =
[]ls.append(100)ls.append(200)lsLength = len(ls)print '\n list length is: ' +
str(lsLength)----------------------------------------------------- Do you know
the reason?
Thank you,Michelle
