If you want to check whether a string contains or doesn’t contain a certain phrase, Python has two keywords that come in handy. These two keywords are in and not in. Both of these keywords are case sensitive when they compare, so the word “Hello” will not match “hello“. "Hello"...

The .isupper() method returns True if the target string isn’t empty and all its alphabetic characters are uppercase. Otherwise, it returns False: Python >>> "ABC".isupper() True >>> "ABC1$D".isupper() True >>> "Abc1$D".isupper() False Again, Python ignores non-alphabetic char...
