Day 64 : Python Program to Remove Odd Indexed Characters in a string

 def remove_odd_indexed_chars(input_string):

    """

    Remove characters at odd indices from the input string.

      Args:

        input_string (str): The string to process.

        Returns:

        str: A new string with characters at odd indices removed.

    """

    return input_string[::2]

Code Explanation:

1. Function Definition

def remove_odd_indexed_chars(input_string):

def: Used to define a function.

remove_odd_indexed_chars: The name of the function, which describes its purpose (removing odd-indexed characters).

input_string: A parameter that represents the input string the user provides.

2. Docstring

    """

    Remove characters at odd indices from the input string.

    Args:

        input_string (str): The string to process.

    Returns:

        str: A new string with characters at odd indices removed.

    """

A docstring provides an explanation of the function:

Purpose: The function removes characters at odd indices.

Args: It expects one argument:

input_string: The string to be processed.

Returns: It outputs a new string with the odd-indexed characters removed.

3. Function Logic

    return input_string[::2]

input_string[::2]: This is a slicing operation. Here's how it works:

Start (start): By default, starts at index 0 (the first character).

Stop (stop): By default, goes to the end of the string.

Step (step): Specifies the interval; 2 means take every second character.

Effect:

Only characters at even indices (0, 2, 4, ...) are retained.

Characters at odd indices (1, 3, 5, ...) are skipped.

The resulting string is returned to the caller.

4. Main Execution Block

if __name__ == "__main__":

if __name__ == "__main__"::

Ensures the code inside this block runs only when the script is executed directly (not imported as a module in another script).

5. Input Prompt

    input_string = input("Enter a string: ")

input("Enter a string: "):

Prompts the user to enter a string.

The entered string is stored in the variable input_string.

6. Function Call

    result = remove_odd_indexed_chars(input_string)

remove_odd_indexed_chars(input_string):

Calls the function remove_odd_indexed_chars with the user-provided string (input_string) as an argument.

The function processes the string and returns a new string with odd-indexed characters removed.

result:

Stores the returned value (the modified string).

7. Output

    print("String after removing odd indexed characters:", result)

print:

Outputs the result to the user.

Displays the modified string with odd-indexed characters removed.
