Question

Write a function that finds the number of occurrences of a specified character in the string using the following header: def count(s, ch): For example, count("Welcome", 'e') returns 2. The str class has the count method. Implement your function without using the count method. Write a test program that reads a string and a character and displays the number of occurrences of the character in the string.

Answer 1

Answer:

def count(userInput, character):

   occurrences = 0

   for character_in_string in userInput:

       if(character == character_in_string):

           occurrences += 1

   return occurrences

userInput = input("Enter string: ")

character = input("Enter character: ")[0]

print(count(userInput, character))

Explanation:

• Define a count function that takes in the userInput as a string and character parameters.
• Loop through the userInput and check whether selected character is equal to the character found in the string.
• Increase the counter of occurrences by 1 if the condition is true and then return the occurrences.
• Take the userInput and character as input from the user.
• Finally display the results by calling the count function.
