Python os.path.isfile() Method

The os.path.isfile() is a built-in Python method that returns True if the path is an absolute pathname.

Syntax

os.path.isfile(path)

Parameters

The os.path.isfile() function takes a path as a parameter representing an object representing a file system path. A path-like object is either a string or bytes object representing a path.

Return Value

The os.path.isfile() method returns a Boolean value of class bool. The os.path.isfile() method returns True if the specified path is an existing regular file. Otherwise, it returns False.

Example 1

Let’s define a folder path and pass that path to the isfile() function.

import os

path = "/Users/krunal/Desktop/code/pyt/database"

isFile = os.path.isfile(path)

print(isFile)

Output

False

You can see that we have passed the folder path and not the file path to the isfile() function; hence, it returns False.

Example 2

import os

path = "/Users/krunal/Desktop/code/pyt/database/app.py"

isFile = os.path.isfile(path)

print(isFile)

Output

True

To check if the file exists in the file system using Python, use the os.path.isfile() function. If you attempt to navigate or open a non-existent file, then this will cause an error. 

That’s it.
