if user input is not a directory, how can I make the directory a default value

Question

Let us say a user input is an invalid directory. if so how can I make a script automatically set a default directory to a local file or the desktop?

Answer 1

You can use

os.path.exists(path)

to see if it exists. If it does not, you can set set another path . If you want to change directory, you can use

os.chdir(path)

Answer 2

You have to use the os library and check if a directory exists:

isFile = os.path.isdir(path) 

if isFile is false then set it to whatever default directory you want. If you want it to be set to Desktop, then use:

os.environ['USERPROFILE'] + '\Desktop'
