Python Program to Remove Odd Indexed Characters in a string

In this program, we will write a Python program to remove the odd-indexed characters from a given string.

Problem statement

Given a string, we need to remove all the characters at odd indices and return the resulting string.

Python Program to Remove Odd Indexed Characters in a string

def remove_odd_indexed_chars(string):
    result = ""
    for index in range(len(string)):
        if index % 2 == 0:
            result += string[index]
    return result

# Test the program
input_string = input("Enter a string: ")
result_string = remove_odd_indexed_chars(input_string)
print("Result:", result_string)

How it works

1. We define a function remove_odd_indexed_chars that takes a string as an input.
2. We initialize an empty string result to store the characters at even indices.
3. We iterate over the range of indices of the string using a for loop and the range function.
4. Inside the loop, we check if the current index is even by using the modulo operator %. If the index is even (i.e., index % 2 == 0), we add the character at that index to the result string using string concatenation.
5. Finally, we return the result string, which contains only the characters at even indices.
