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.
