how to check if a file exists in python

import os

os.path.exists("file.txt") # Or folder

import os.path

if os.path.isfile('filename.txt'):
    print ("File exist")
else:
    print ("File not exist")

import os.path

if os.path.isfile('filename.txt'):
    print ("File exist")
else:
    print ("File not exist")

import os
file_exists = os.path.exists("example.txt") # Returns boolean representing whether or not the file exists

#using pathlib
from pathlib import Path

file_name = Path("file.txt")
if file_name.exists():
    print("exists") 
else:
    print("does not exist") 

# Python program to explain os.path.exists() method   
      
# importing os module   
import os  
    
# Specify path  
path = '/usr/local/bin/'
    
# Check whether the specified  
# path exists or not  
isExist = os.path.exists(path)  
print(isExist)  
    
    
# Specify path  
path = '/home/User/Desktop/file.txt'
    
# Check whether the specified  
# path exists or not  
isExist = os.path.exists(path)  
print(isExist)
