Python Program to Calculate the Length of a String Without using Library Functions

This is a Python Program to calculate the length of a string without using library functions.

The program takes a string and calculates the length of the string without using library functions.

1. Take a string from the user and store it in a variable.
2. Initialize a count variable to 0.
3. Use a for loop to traverse through the characters in the string and increment the count variable each time.
4. Print the total count of the variable.
5. Exit.

Here is source code of the Python Program to calculate the length of a string without using library functions. The program output is also shown below.

string=raw_input("Enter string:")
count=0
for i in string:
      count=count+1
print("Length of the string is:")
print(count)

1. User must enter a string and store it in a variable.
2. The count variable is initialized to zero.
3. The for loop is used to traverse through the characters in the string.
4. The count is incremented each time a character is encountered.
5. The total count of characters in the string which is the length of the string is printed.

 
Case 1:
Enter string:Hello
Length of the string is:
5
 
Case 2:
Enter string:Bangalore
Length of the string is:
9
