I am surprised that it took me so long to bloody my nose on this one.
It must be well known - and I would like to find out how well known.
So here is a CLOSED BOOK multiple choice question - no RTFM,
no playing at the interactive prompt:
Given the following three lines of code at the interactive prompt:
foo = [1,2,3,4]
x = foo.append(5)
What will be the output (choose one):
3) That famous picture of Albert Einstein sticking out his tongue
4) Nothing - no output
5) None of the above
I undertake to summarise answers posted to complete this "survey".
