You can use the os.path.getsize() function from the os module to get the size of a file in bytes.

Code Example:

import os

file_path = "example.txt"
file_size = os.path.getsize(file_path)
print(f"The size of {file_path} is {file_size} bytes.")

This code retrieves the size of the file specified by file_path and prints it in bytes.
