Is there a magic method in python for the "in" method? For example,
y = [5, 4, 3, 2,1]
5 in y #returns true
if so what is it, and if not, how would one implement it.

Try it and you'll know. – Maroun Oct 05 '14 at 14:55

Special methods are documented in section 3.3 of the reference manual, which has subsections like 3.3.6 'Emulating Container Types'. – Terry Jan Reedy Oct 05 '14 at 16:45

It's __contains__():
>>> y = [5, 4, 3, 2, 1]
>>> y.__contains__(3)
True
>>> y.__contains__(6)
False
