Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])
