What is Python
The Python programming language is one of the most popular general-purpose programming languages. Python is used for server-side programming, machine learning, application testing, and as "glue code" to connect different components from different applications written in different programming languages. Python has dynamic typing and dynamic binding, and an integrated garbage collector.The Python programming language runs on almost all operating systems, such as Windows, Linux, and macOS. Python is a straightforward programming language to learn and maintain. Python has built-in modules for working with JSON, strings, HTTP requests, and XML out of the box.
What is OS Module in Python?
In Python, the OS Module provides various methods to interact with the operating system. The OS Module is included in standard Python utility modules. The OS module provides a portable way to use operating system-specific features. The OS Module hides the difference for a Python programmer between different operating systems. In addition to methods for checking the existence of files on disk, the OS module contains an extensive set of useful functions that are used to interact with the computer's operating system. To use the os module, it must first be imported so that we can call methods to interact with the file and the operating system:
Check if a file exists in Python using os.path.isfile() Method
To check if a file exists in Python, you can use the os.path.isfile() method. Pass a file name and a relative or absolute path to the file as an argument to this function. The method returns True if the file is present, and False otherwise.
Check if a file exists in Python using os.path.exists() Method
To check if a file exists in Python, you can use the os.path.exists() method. The method returns True if the path is a regular file, directory, or a valid symbolic link.
How to check if a directory exists in Python?
To check if a directory exists in Python, you can use the os.path.isdir() method. The os.path.isdir() method returns True if the path is a directory or a symbolic link to a directory:
