In this post, we will learn to check if a file or folder exists

Check if a file exists using ‘isfile’ function

# import the os.path module in order to use isfile function
import os.path

# specify the file we desire to check
fPath = r'C:\Users\Nagasudhir\Documents\Python Projects\substation_pmu_dict_synthesis\index.py'

# use isfile function
isFilePresent = os.path.isfile(fPath)
if isFilePresent:
	print('File is present!!!')
else:
	print('File does not exist...')

Check if a folder exists using ‘isdir’ function

# import the os.path module in order to use isdir function
import os.path

# specify the folder we desire to check
fPath = r'C:\Users\Nagasudhir\Documents\Python Projects'

# use isdir function
isFolderPresent = os.path.isdir(fPath)
if isFolderPresent:
	print('Folder is present!!!')
else:
	print('Folder does not exist...')
