Question

Python 3:

Write a function CharCount, to take a string S and a single character C, and returns the count of C (one letter) in the string S. If the letter of C is not found in S, the function returns -1. You must write your own function to do this and can not use any built-in counting functions.

Use the function in main to get two inputs from the user, a sentence and a character, then show the count of that character or an error message if the count is -1.

Answer 1

here i have written the complete code as per the requirement.

==================================================================

Program:

===================================================================

#function definition

def CharCount(S, C):

    #initialize count to zero

    count = 0

    #iterate through String

    for i in S:

        #if char is matched then increment the count

        if i == C:

            count = count + 1

    #if no char is found return -1

    if count == 0:

        return -1

    else:

        return count

#inputs

string = str(input("Enter a sentence: "))

char   = str(input("Enter a character: "))

#call to function

res = CharCount(string, char)

#if res is -1

if res == -1 :

    print("input character is not found in the sentence.")

#else print the total count

else:

    print("Total count of ", char, " is = ", res)
