4. Using os.path.exists() 5. Conclusion 1. Introduction to the Problem Statement In Python, ensuring that a file is created only if it does not already exist is a common operation in many applications like data logging, file manipulation, or when working with temporary files. This operation...
In this example, we use atryandexceptblock to catch theFileNotFoundErrorexception that is raised if the file does not exist. We try to open the file:with open(file_path) as f:and if the file exists, weprinta message indicating that the file exists. If the file does not exist, we ...
