Solution Exercise 25: list of words that do not contain the letter 'a' in a given text

Exercise 25

Write a Python program that determines the list of words not containing the letter 'a' in a given text.

Solution

def wordWithout_a (T):
     #initialize the list of words which do not contain the letter a
     listWordWithout_a = []
     # convert text T to a list
     L = T.split ()
     # browse the words of the list L and find those which do not contain the letter a
     for word in L:
          if 'a' not in word:
               listWordWithout_a.append (word)
     return listWordWithout_a

# Example
T = "Python is a high level programming language"
print ("the list of words which do not contain the letter 'a' is:", wordWithout_a(T))
# The output is: the list of words which do not contain the letter 'a' is: ['Python', 'is', 'high', 'level']
