Solution

import re # library for regular expression
sentence = raw_input(\"please enter the sentence: \")

sentence = sentence.lower() # chance the sentence into lowercase
sentence = re.sub(r\'\\s+\', \'\', sentence) # remove all white spaces

list_of_sen = list(sentence) # make an array of charecter from sentence
set_list = set(list_of_sen) # remove all repetative charecter from list

if len(set_list) == 26: # if set list conatains 26 letter print true
   print \"True\"
else:
   print \"False \"
