Write function countLetter that takes a word as a parameter and returns a dcitionary that tells us how many times each alphabet appears in the word (no need to account for absent alphabets). Develop your logic using dictionaries only. Save the count result as a dictionary. Display your output in the main() function.

Answer:

Following are the program in the Python Programming Language:

def countLetter(words):

   #set dictionary

 di = {}

 for i in words: #set for loop

 #if key exists in di or not

   if di.get(i):

 #if exists count increased

     di[i] += 1

   else: #otherwise assign with key

     di[i] = 1

   # return di

 return di

def main():

 #get input from the user

 words = input("Enter the word: ")

 #store the output in function

 letter = countLetter(words)

 #set for loop

 for i in letter:

   print(i, ":", letter[i])  #print output with :

#call main method

if __name__ == "__main__":

 main()

Explanation:

Here, we define the function "countLetter()" and pass the argument "words" in parameter and inside it.

  • we set the dictionary data type variable "di".
  • we set the for loop and pass the condition inside it we set if statement and increment in di otherwise di is equal to 1.
  • we return the variable di.

Then, we define the function "main()" inside it.

  • we get input from the user in the variable "words".
  • we store the return value of function "countLetter()" in the variable "letter".
  • we set for loop to print the output.

Finally, we call the main method.
