Python 3 introduced thepathlibmodule, which offers an object-oriented approach to handle filesystem paths. It’s more intuitive and easier to work with compared to theosmodule. Here’s how you can use it to check if a file exists: frompathlibimportPath file_path=Path('your_file.txt')iffil...
To check if an element exists in a list using the Counter() function from Python's collections module, you first create a Counter object from the list. This object counts how many times each element appears in the list. Then, you can simply check if the element is a key in the ...
isdir(object) where object is the name of the directory you want to check the status of. Example In the following example, let us try to check if a directory exists or not using the isdir() method. Since the method returns a Boolean type values, we are using the conditional statements...

Since Python 3.4, it introduces an object-oriented method inpathlibmodule to check if a file exists. frompathlibimportPath fileName="temp.txt"fileObj=Path(fileName)print(fileObj.is_file()) Similarly, it has alsois_dir()andexists()methods to check whether a directory or a file/directory ex...

Does demo.txt exists False Method-3: Using the pathlib module The pathlib module manipulates files and folders using the object-oriented approach. Firstly, we will need to import the Path class from the pathlib module. Thereafter, create a new instance of Path class and initialize it with the...
