Replacing the Middle Digit of a Three-Digit Number with Zero in Python

To replace the middle digit of a three-digit number with zero in Python, you can follow these steps:

1. Input the Three-Digit Number - Use the `input()` function to prompt the user to enter a three-digit number. - Convert the input to an integer using the `int()` function.

   n = int(input("Enter a three-digit number: "))
   

2. Extract the Digits - Use the modulo operator `%` to extract the individual digits of the number. - Store the digits in a list.

   x = [n // 100, 0, n % 10]
   

3. Calculate the Result - As the middle digit is replaced with zero, the new number can be obtained by multiplying the hundreds digit by 100 and adding the units digit.

   result = x[0] * 100 + x[2]
   

4. Print the Result - Use the `print()` function to display the resulting number.

   print("The number after replacing the middle digit with zero is:", result)
   

Example

If the input is 123, the output will be 103.

This Python code allows you to replace the middle digit of a three-digit number with zero and obtain the resulting number.
