is_pangram.py

# Description:
# A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the
# sentence "The quick brown fox jumps over the lazy dog" is a pangram, because it uses the letters A-Z at least once
# (case is irrelevant).
# Given a string, detect whether or not it is a pangram. Return True if it is, False if not. Ignore numbers and
# punctuation.
# Examples:
# is_pangram("pangram") -> False
# is_pangram("The quick brown fox jumps over the lazy dog") -> True
