In this article we will show you the solution of python check if file exists, when working with files in Python, there may be times when you need to check whether a file exists or not. A confirmation of the existence of a specific file is useful when attempting to perform particular operations, such as reading or writing to it.

In the event that any of the above operations cannot be performed because the file does not exist, you will meet bugs and your program will crash.

Therefore, if you want to perform operations and prevent your program from crashing, checking whether a file exists on a given path is a helpful first step.

When processing files, you’ll often want to check if a file exists before doing something else with it such as reading from the file or writing to it.

We will now discuss the idea of how to check if a file exists in python with an example.

Step By Step Guide On Python Check If File Exists :-

import os.path
# Create a directory
dirname = "Talkers Code"
os.mkdir(dirname)
# Create a symbolic link
# pointing to above directory
symlink_path = "/home/User/Desktop/tc"
os.symlink(dirname, symlink_path)
path = dirname
# Check whether the specified path is an
# existing directory or not
isdir = os.path.isdir(path)
print(isdir)
path = symlink_path
# check whether the symlink is
# an existing directory or not
isdir = os.path.isdir(path)
print(isdir)

1. Import the os.path module.
2. Set the directory name to be created as a string variable dirname.
3. Create the directory using the os.mkdir() function and passing in the dirname variable.
4. Set the symbolic link path as a string variable symlink_path.
5. Create the symbolic link using the os.symlink() function, passing in the dirname and symlink_path variables.
6. Set the directory path to be checked as a string variable path and assign it to the dirname variable.
7. Check if the path is an existing directory using the os.path.isdir() function and passing in the path variable. Assign the result to a variable called isdir.
8. Print the value of isdir.
9. Set the directory path to be checked as a string variable path and assign it to the symlink_path variable.
10. Check if the symlink is an existing directory using the os.path.isdir() function and passing in the path variable. Assign the result to a variable called isdir.
11. Print the value of isdir.

Conclusion :-

As a result, we have successfully learned how to check if an existing file exists in python with an example.

A file can be checked for existence in Python using a variety of methods. We have explained different methods in this article.

I hope this article on python check if file exists helps you and the steps and method mentioned above are easy to follow and implement.
