The role of this function is to obtain the name of a file that does not exist.

the_name = fl.get_new_file_name('test', 'dat')
the_name

'test.dat'

Now, let’s create that file, and call the function again. A suffix with a number is appended to the name of the file, before its extension.

open(the_name, 'a').close()

the_name = fl.get_new_file_name('test', 'dat')
the_name

'test~00.dat'

If we do it again, the number is incremented.

open(the_name, 'a').close()

the_name = fl.get_new_file_name('test', 'dat')
the_name

'test~01.dat'
