Python!
Look at image. Thanks!

Extracted text: Define a function named swap_values that takes four integers as parameters and swaps the first with the second, and the third with the fourth values. Then write a main program that reads four integers from input, calls function swap_values() to swap the values, and prints the swapped values on a single line separated with spaces. Ex: If the input is: 3 8. 2 4 function swap_values() returns and the main program outputs: 8 3 4 2 The program must define and call the following function. def swap_values(user_val1, user_val2, user_val3, user_val4)
