Python Program to Check the File Size

In this example, you will learn to check the file size.

To understand this example, you should have the knowledge of the following Python programming topics:

• Python Directory and Files Management

1. 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.

2. 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.
