Python3

Answer 1

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.
