Python Code: # Import the 'os' module to access operating system functionalities.importos# Define the path to a file or directory named 'abc.txt'.path="abc.txt"# Check if the path refers to a directory.ifos.path.isdir(path):# Print a message indicating that it is a directory.print("...
file to see how the nested “if-else” statement reacts while using the flags “-d” and “-f”. This time we will use the directory path. Open the file once again and update the variable path value. We have replaced “test.txt” with “Documents/”. The remaining script is the ...
Note: In Python 2 this was anIOError. Useos.path.isfile(),os.path.isdir(), oros.path.exists()¶ If you don’t want to raise an Exception, or you don’t even need to open a file and just need to check if it exists, you have different options. The first way is using the ...
A step-by-step guide on how to check if a file path is a symlink (symbolic link) in Python in multiple ways.
The os.path.exists() method provided by the os standard library module returns True if a file exists, and False if not.Here is how to use it:import os filename = '/Users/flavio/test.txt' exists = os.path.exists(filename) print(exists) # True...
Checking if Either Exist Another way to check if a path exists (as long as you don't care if the path points to a file or directory) is to useos.path.exists. importos os.path.exists('./file.txt')# Trueos.path.exists('./link.txt')# Trueos.path.exists('./fake.txt')# Falseos...
Checking if a Directory Exists Like theisfilemethod,os.path.isdiris the easiest way to check if a directory exists, or if the path given is a directory. importos os.path.isdir('./file.txt')# Falseos.path.isdir('./link.txt')# Falseos.path.isdir('./fake.txt')# Falseos.path.isdir...
