Python Program to Count Occurrence of a Character in a String

Write a Python Program to Count the Occurrence of a Character in a String with a practical example. This Python program allows you to enter a string and a character.

string = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

count = 0
for i in range(len(string)):
    if(string[i] == char):
        count = count + 1

print("The total Number of Times ", char, " has Occurred = " , count)

Here, we used For Loop to iterate each character in a String. Inside the Python For Loop, we used the If statement to check whether any character in a string is equal to the given character or not. If true, then count = count + 1.

string = tutorial gateway
ch = t
count = 0

For Loop First Iteration: for i in range(11)
if(string[i] == char)
if(t == t) – Condition is True.
count = 0 + 1 => 1

Second Iteration: for 1 in range(11)
if(u == l) – Condition is false.

Third Iteration: for 2 in range(11)
if(string[2] == char) => if(t == t) – Condition is True.
count = 1 + 1 => 2

Do the same for the remaining Program iterations

Python Program to Count Occurrence of a Character in a String using While

This counting of the total occurrence of a character in a string program is the same as the above. However, we just replaced the For Loop with the While Loop.

string = input("Please enter your own String : ")
char = input("Please enter your own Character : ")
i = 0
count = 0

while(i < len(string)):
    if(string[i] == char):
        count = count + 1
    i = i + 1

print("The total Number of Times ", char, " has Occurred = " , count)

The total character occurrence in a string output.

Please enter your own String : python programs
Please enter your own Character : p
The total Number of Times  p  has Occurred =  2
>>> 
Please enter your own String : hello
Please enter your own Character : l
The total Number of Times  l  has Occurred =  2

Program to Count Total Occurrence of a Character Example 3

This total occurrence of a given Character program is the same as the first example. But, this time, we used the Functions concept to separate the logic.

def count_Occurrence(ch, str1):
    count = 0
    for i in range(len(string)):
        if(string[i] == char):
            count = count + 1
    return count

string = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

cnt = count_Occurrence(char, string)
print("The total Number of Times ", char, " has Occurred = " , cnt)

The total number of character occurrence in a string output

Please enter your own String : Python tutorial
Please enter your own Character : t
The total Number of Times  t  has Occurred =  3
>>> 
Please enter your own String : hi
Please enter your own Character : g
The total Number of Times  g  has Occurred =  0
