In this example, we first import theosmodule. We then define a variablefile_paththat holds the name of the file we want to check. We pass this variable to theos.path.exists()function inside anifstatement. If the file exists, it prints ‘The file exists!’, and if it doesn’t, it p...

When operating with files, you will always need to check for the existence of file before using it for reading from orwriting to them. While working on any applications associated with the file, it is required that all the files must be present to proceed further. So, we can use functions...
