Traceback (most recent call last): File "main.py", line 4, in <module> if (year % 4) == 0:TypeError: not all arguments converted during string formatting

The error message you're encountering indicates a problem with the data type being used in your code. Specifically, it looks like a TypeError is being raised when trying to perform a modulo operation on the variable year. This usually happens if year is of the wrong type (like a string) instead of an integer.

To fix this issue, you'll need to ensure that year is converted to an integer before performing the modulo operation. Here's how you can resolve the error:

1. Check the variable assignment: Make sure that year is assigned a numeric value.
2. Convert to integer: If year comes from user input or a source that provides it as a string, use int() to convert it.

Example Code Fix

Here's an example of how you might structure your code:

# Get user input and convert to integer
year_input = input("Enter a year: ")  # Example: "2024"
year = int(year_input)  # Convert the input string to an integer

# Check if it's a leap year
if (year % 4) == 0:
    print(f"{year} is a leap year.")
else:
    print(f"{year} is not a leap year.")

Summary

• Ensure that the year variable is an integer before performing calculations.
• Use int() to convert string inputs to integers.

Make sure to test your program after making these changes to confirm that the error has been resolved and that it behaves as expected.
