Question

I’ve written a python code which takes input from the user and manipulates the inputs to provide result.
I want in that to provide a help like function which appears if the user left one of the entry blank.

    dir  = raw_input("Enter dir:")
    path = raw_input("Enter path:")

    print random_method(dir, path)

Now if the user did not enter any value for dir or path, there must be a warning or a guidance to tell before python raises it’s own errors.

Thanks

Do you mean like this:

dir  = raw_input("Enter dir:")
if not dir:
    dir = raw_input("Do you really want to leave a blank? Enter dir:")
path = raw_input("Enter path:")
if not path:
    path = raw_input("Do you really want to leave a blank? Enter dir:")
