python - Upper case first letter of each word in a phrase

Question

Ok, I'm trying to figure out how to make a inputed phrase such as this in python ....

Self contained underwater breathing apparatus

output this...

SCUBA

Which would be the first letter of each word. Is this something to do with index? and maybe a .upper function?

Answer 1

This is the pythonic way to do it:

output = "".join(item[0].upper() for item in input.split())
# SCUBA

There you go. Short and easy to understand.

LE: If you have other delimiters than space, you can split by words, like this:

import re
input = "self-contained underwater breathing apparatus"
output = "".join(item[0].upper() for item in re.findall("w+", input))
# SCUBA
