How to check file size in Python?

Prerequisites:

• os 
• pathlib

Given a file, the task here is to generate a Python Script to print its size. This article explains 2 methods to do so.

Approach

• Import module
• Get file size

File in use

Name: Data.csv

Size: 226 bytes

Method1: Using pathlib

Path().stat().st_size() function of pathlib module gets the size of any type of the file and the output of this function will be the size of the file in bytes.

Syntax:

Path('filename').stat().st_size()

Example:

Python3

from pathlib import Path

sz = Path('Data.csv').stat().st_size

print(sz)

Output:

Method 2: With Os module

os.path.getsize() function only works with os Library, with the help of importing this library we can use this to get the size of any type of file and the output of this function will be the size of the file in bytes.

Syntax:

getsize(filename)

Example:

Python3

import os

sz = os.path.getsize("Data.csv")

print(sz)

Output:

We got the result as 226 bytes
