How do I check whether a file exists without exceptions?
There are two ways you can safely check if a file exists at a given path.
Using the os.path
You can use the exists function from the os.path
package to check if a file exists at the given path.
from os.path import exists
file_exists = exists('/directory/some_file.txt')
Using the pathlib
Also, you can use the Path class and use the is_file method.
from pathlib import Path
path = Path(path_to_file)
file_exists = path.is_file()
