I have a string like "asdfHRbySFss" and I want to go through it one character at a time and see which letters are capitalized. How can I do this in Python?

In Python, isupper() is a built-in method used for string handling. This method returns True if all characters in the string are uppercase, otherwise, returns “False”.
To check if a letter in a string is uppercase or lowercase use the toUpperCase() method to convert the letter to uppercase and compare it to itself. If the comparison returns true , then the letter is uppercase, otherwise it's lowercase. Copied!
To check if a character is upper-case, we can simply use isupper() function call on the said character.
Use string.isupper()
letters = "asdfHRbySFss" uppers = [l for l in letters if l.isupper()] if you want to bring that back into a string you can do:
print "".join(uppers) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
