Question

Python3

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 1

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()

Step-by-step 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.
