Python Test If a Document Exists The use of os.trail & pathlib: Be told Now

Give an explanation for Python exists()

The OS module in Python shall we us engage with the working gadget. This comes beneath Python’s same old software modules and provides a conveyable manner to make use of the dependent purposes of the working gadget. The exists() serve as in Python exists within the os.trail module, which is a submodule of the python’s OS module and is used to test if a selected document exists or now not.

Syntax

from os.trail import exists

file_exists = exists(path_to_file)

Other Tactics to Test a Document or Python Test if Listing Exists, The use of Purposes

There are a couple of techniques to test if a document or listing exists or now not. On this present article, we’re going to carry out this test the use of Python purposes. A few of them are defined in short below-

Find out how to Test if a Document Exists in Python The use of:

1. os.trail.exists()

As discussed in an previous paragraph, we all know that we use os.trail.exists() to test if a document or listing exists the use of Python. We additional use this technique to test if a selected document trail refers to an already open descriptor or now not.

Serve as Syntax

os.trail.exists(trail)

Parameter

Go back sort – Go back a boolean sort worth, i.e., false if the trail does now not exist and true if it exists.

trail – A string sort or bytes sort object regarding a gadget trail.

Instance

import os

# Specifying trail

trail = ‘/usr/native/bin/’

# Checking whether or not the desired trail exists

isExisting = os.trail.exists(trail)

print(isExisting)

# Specifying trail

trail = ‘/house/Consumer/Diksha/Desktop/document.txt’

# Checking whether or not the desired trail exists

isExisting = os.trail.exists(trail)

print(isExisting)

Output

False

True

2. os.trail.isfile()

os.trail.isfile() is every other way this is used to test if a selected common document in Python exists or now not.

Serve as Syntax

os.trail.isfile(trail)

Parameter

Go back sort – Go back a boolean sort worth.

trail – A string sort or bytes sort object regarding a gadget trail.

Instance

import os

# defining Trail

trail = ‘C:/Customers/simplilearn/Desktop/document.txt’

# Checking whether or not the desired trail exists

isFile = os.trail.isfile(trail)

print(isFile)

# defining Trail

trail = ‘/house/Consumer/Diksha/Desktop/’

# Checking whether or not the desired trail exists

isFile = os.trail.isfile(trail)

print(isFile)

Output

True

False

3. os.trail.isdir()

This serve as is used to test if a specified trail exists in a listing or now not. The required trail follows a symbolic trail linking to the desired listing. 

Serve as Syntax

os.trail.isdir(trail)

Parameter

Go back sort – Returns a boolean sort worth, i.e., false if the desired trail to the present does now not exist, true if it does.

trail – os.trail.isdir(trail)

Instance 1

import os.trail

# defining Trail

trail = ‘/house/Consumer/Paperwork/document.txt’

# Test whether or not the desired trail exists

isdir = os.trail.isdir(trail)

print(isdir)  

# defining Trail

trail = ‘/house/Consumer/Paperwork/’  

# Test whether or not the desired trail exists

isdir = os.trail.isdir(trail)

print(isdir)

Output

True

False

Instance 2 – To Test if the Specified Trail Is a Symbolic Trail

import os.trail

# Making a listing

dirname = “Simplilearn”

os.mkdir(dirname)   

# Making a symbolic hyperlink to indicate to above listing

symbolink_path = “/house/Consumer/Desktop/simp”

os.symlink(dirname, symbolink_path)   

trail = dirname   

# Checking if 

# specified trail is an present listing 

isdir = os.trail.isdir(trail)

print(isdir)

trail = symbolink_path

# Checking whether or not the desired trail

# is an present listing

isdir = os.trail.isdir(trail)

print(isdir)

Output

True 

True

4. pathlibPath.exists()

The Python Pathlib module incorporates numerous categories that describe document gadget paths and feature semantics which are applicable for more than a few working methods. This module is a part of Python’s same old software module assortment. Concrete and Natural paths are the 2 varieties of trail categories within the pathlib module. Natural routes simplest carry out computations and don’t carry out I/O operations, while concrete pathways are inherited from natural paths and carry out each I/O and computational actions.

The pathlib.Trail.exists() way is principally used to test if the given trail issues to an present listing or a document.

Serve as Syntax

pathlib.Trail.exists(trail)

Parameter

Go back sort – Go back a boolean sort worth, true if the trail exists, false if it does now not.

trail – Object that represents the gadget trail.

Instance

from pathlib import Trail

# defining Trail

trail = ‘/house/simplilearn/Desktop’   

# Instantiating the Trail elegance

obj = Trail(trail)   

# Checking if the trail issues to and present document 

print(obj.exists())

Output

True
