Check if string is upper, lower, or mixed case in Python

I want to classify a list of string in Python depending on whether they are upper case, lower case, or mixed case How can I do this?
There are a number of "is methods" on strings. islower() and isupper() should meet your needs: >>> 'hello'.islower() True >>> [m for m in dir(str) if m.startswith('is')] ['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper'] Here's an example of how to use those methods to classify a list of strings: >>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG'] >>> [word for word in words if word.islower()] ['quick', 'jumped', 'the'] >>> [word for word in words if word.isupper()] ['BROWN', 'OVER', 'DOG'] >>> [word for word in words if not word.islower() and not word.isupper()] ['The', 'Fox', 'Lazy']
