2. Write a function avg_lowest that takes 3 floating values as parameters and returns the average of the two smaller values. For example, if the input is 2.0, 9.0, 4.0, the output should be 3.0; if the input is 11.5, 6.3, 3.7, the output should be 5.0. Save the function in a PyDev library module named functions.py. A sample run for the function avg_lowest (2.0, 9.0, 4.0) -> 3.0 Write a testing program named to2.py that tests your function by asking the user to input three floating values and printing the average of two smaller values. A sample run of your program: Please enter your first number: 11.5 Please enter your second number: 6.3 Please enter your third number: 3.7 The average of the two smaller value is: 5.0 Or A sample run of your program: Please enter your first number: 6.3 Please enter your second number: 6.3 Please enter your third number: 3.7 The average of the two smaller value is: 5.0 . . Test your program with 3 different data, you may assume that the user will only enter numbers. Copy the results to testing.txt. You are not allowed to use the built-in functions max or min
