Python Program to Check the File Size

Example 1: Using os module

import os

file_stat = os.stat('my_file.txt')
print(file_stat.st_size)

Output

34

Using stat() from the os module, you can get the details of a file. Use the st_size attribute of stat() method to get the file size.

The unit of the file size is byte.

Example 2: Using pathlib module

from pathlib import Path

file = Path('my_file.txt')
print(file.stat().st_size)

Output

34

Using the pathlib module, you can do the same thing as shown above. The unit of the file size is byte.
