How to remove specific substrings from a set of strings in Python?

Question

I have a set of strings set1, and all the strings in set1 have a two specific substrings which I don\'t need and want to remove.
Sample Input

Answer 1

>>> x = 'Pear.good'
>>> y = x.replace('.good','')
>>> y
'Pear'
>>> x
'Pear.good'

.replace doesn't change the string, it returns a copy of the string with the replacement. You can't change the string directly because strings are immutable.

You need to take the return values from x.replace and put them in a new set.
