[Tutor] multiple if and or statement

[Mike Franon]

Thank you everyone who responded, very fast responses I am impressed.

OK now I see where I went wrong and had to do


if (i == 'test1') or (i=='test2'):


I guess I was thinking if I do


a = ['test1', 'flag', 'monday']
for i in a:

It would check each item in the list one at a time like a loop I was
thinking, so the first time it would test for 'test1', and the second
time it would test for 'flag', did not realize it would test the
entire list all at once.
