Finding something in a list#

The following function contains_2(lst) is partially complete. Replace each CHANGEME such that the function returns True once it finds a 2 in lst, or False if there is no 2 in lst. You can assume lst is a list of integer values.

Hint: for the first CHANGEME you will decide the name of this variable.

(You might think… can’t I just use in to do that? Indeed you can… but I’d like you to implement your own version of in!)
