For this program we were supose tu search for the word “banana” in a file, even if the word is written in upper or lower cases.

This was a very similar to the WSQ10. First we need to make a file, in this case, and for obviusly reasosn, I call it “banana.txt”. We have to open the file, then, to ingonre when the word is written u¡in upper or lower, we can change the hole file to lower cases.
