python - if not in list [duplicate]

Question

I have two lists:

mylist = ['total','age','gender','region','sex'] checklist = ['total','civic'] 

I have to work with some code I have inherited which looks like this:

for item in mylist:     if item in checklist:         do something: 

How can I work with the code above to tell me that 'civic' is not in mylist?.

This would've been the ideal way to do it but I cant use it, don't ask me why.

for item in checklist:     if item not in mylist:         print item 

Outcome:

civic
