Check if a File or Directory Exists
In Python, you can determine whether a file or directory exists by using the os.path.exists() function or the os.path.isfile() and os.path.isdir() functions from the os module. Here's how to achieve this with examples:
Using os.path.isfile() and os.path.isdir()
Using try-except block
Here is an example of how to check that a file or directory exists using the try-except block:
This code will try to open the file my_file.txt. If the file exists, the code will print "The file or directory exists." If the file does not exist, the code will catch the FileNotFoundError exception and print "The file or directory does not exist."
These examples demonstrate how to use these functions to ascertain the existence of files and directories. Proper validation of existence can help you avoid errors and ensure smooth program execution.
