Check whether a string is a pangram or not

Write a python function to check whether

a string is a pangram or not.

Note :

Pangrams are words or sentences containing

every letter of the alphabet at least once.

For example :

“The quick brown fox jumps over the lazy dog”

import string, sys

def ispangram(S, alphabet=string.ascii_lowercase):

    alphaset = set(alphabet)

    return alphaset <= set(S.lower())

# test
S = 'The quick brown fox jumps over the lazy dog'
print (ispangram(S))          # True
