Using Python – Check if file exists in a path
Python is a versatile programming language that is widely used for a variety of tasks. One of the common tasks is to check if a file exists in a specific path.
In this article, we will discuss how Python check if file exists in a given path using the os.path library in Python.
Checking File Existence with Python’s os.path Library
Python’s os.path library provides two functions, os.path.exists() & os.path.isfile(), that can be used to check if a file exists in a given path. Both functions take the same parameter, the file path, and return a boolean response of True if the file exists or False if it does not.
Here is an example of how to use these functions in Python
#Import path library in Python import os.path fpath = 'C:/Users/hp/Downloads/tee-1252397_640.jpg'; #Check if File exists - Method1 bfileExists = os.path.exists(fpath); print (bfileExists); #Check if File exists - Method2 bfileExists = os.path.isfile(fpath); print (bfileExists); #Print Message as per Return code if bfileExists == True: print ("File Exists"); else: print ("File Does not Exist"); print ("Program Completed");
These functions does not accept wild card characters as input. So, give a proper file path.
os.path.exists() function checks if the specified file path exists, while the
os.path.isfile() function checks if the specified file path is a file and not a directory.
Also, this function does not check if the file can be accessed or it does not have any permission to access. These should be handled using error handling mechanism as discussed in this external link. Click here to read more about it.
Limitations of ‘Python File exist’ functions
It’s important to note that these functions do not accept wildcard characters as input, so you must provide a proper file path. Additionally, these functions do not check if the file can be accessed or if the user has permission to access the file.
These checks should be handled using error handling mechanisms, which can be found in the official Python documentation or through external resources.
Python Path Exists & Isfile
Overall, the os.path library in Python provides a reliable and efficient way to check if a file exists in a specific path. By using the
os.path.isfile() functions, developers can easily check if a file exists in a given path and take appropriate action. It’s a simple yet powerful tool that can help optimize your Python code and improve the overall efficiency of your programs.
