Answer 1

It is already well explained in the module...

the decor function having nested wrap function & (func) as parameter will return wrap function...

1st the print_text() func is passed as parameter to decor function...

so wrap function begins
1--> prints the 1st string "====="
2--> calls the func() which returns the print_text function & prints out "Hello World!"
3--> prints the last string "====="

2nd time print_exit() is passed as parameter...
same thing repeats this time "Exit" will be printed... instead of "Hello World!"
