Practical 9: Program That Counts the Occurrences of a Character in a String Without Using Built-in Functions.
Problem Statement
Write a Python program that accepts a string from the user and a character to search for. The Program That Counts the Occurrences of a Character in a String Without Using Built-in Functions.
Solution Code
# Program to count occurrences of a character in a string without using built-in functions
# Taking input from the user
string = input("Enter a string: ")
char_to_find = input("Enter the character to count: ")
# Initializing counter variable
count = 0
# Loop through each character in the string
for char in string:
if char == char_to_find:
count += 1 # Increment count if match is found
# Displaying the result
print(f"The character '{char_to_find}' appears {count} times in the string.")
Output
- The program takes a string and a character as input.
- It loops through the string and manually counts the number of occurrences of the given character.
- Finally, it displays the count.
Example output:
Enter a string: Banana
Enter the character to count: a
The character 'a' appears 3 times in the string.
Process finished with exit code 0
Explanation
Below is the explanation of F.E. PPS Unit 3 Practical 9 solution where we have written Python Program That Counts the Occurrences of a Character in a String Without Using Built-in Functions.
- Taking User Input:
- The user enters a string and a character to search for.
- Initializing the Counter:
- A variable count is initialized to 0 to keep track of occurrences.
- Iterating Through the String:
- A for loop is used to traverse each character in the string.
- If the character matches the user-provided character, count is incremented.
- Displaying the Count:
- The total occurrences of the character are displayed after the loop completes.
Key Concepts Learned
- String Traversal Using Loops
- Using a for loop to iterate over a string.
- Manual Counting Without Built-in Functions
- Implementing character counting logic manually.
- Conditional Statements (if)
- Checking for character matches within the loop.
