Write a python program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 3 8 the output is: 8 3 Your program must define and call the following function. swap_values() returns the two values in swapped order. def swap_values(user_val1, user_val2)   I can get the first input to reverse but the subsequent outputs I am struggling to make work.

In Python using str(pd.Timestamp.now())[11:13] to get the current number of hours since midnight, write a function that returns a different greeting depending on the time of day. (Hint: use a time argument that defaults to str(pd.Timestamp.now())[11:13] so that you can test your function.)

Use python

Write a function that receives a positive integer n as a parameter, then it must calculate the sum 1+2+3+...+n. Finally return the result of the sum and in the main function print that result to the screen. The output of the program should be just the value of the sum. Look at the example. Input: A positive integer n Output: The result of the addition 1+2+3...+n Program execution example: Entry 6 Departure twenty-one Entry 5Output fifteen Entry 7 Departure 28
