Question

For example, I have a text like this:

This is my String

I would like to grab TS, I would like to grab the upper case only.

Answer 1

You can use the str.isupper predicate method in conjunction with filter in order to filter out the uppercase characters.

If you want the result to be a string, not a sequence, join it with ''.join.

>>> print(''.join(filter(str.isupper, "This is my String")))
