Create a Python script file called Assignment$\_$Ch$04-1\_$yourLastName.py$.($Replace yourLastName with your last name.$)$

Write a Python program prompts the user to input number of hours worked, hourly rate and output pay amount. If hours worked is over $40$ hours, calculate overtime pay $(1\mathrm{.}5$ times of hourly rate$).$ If hours worked is over $60$ hours, calculate double overtime pay $(2$ times of hourly rate$).$ Also, if user enters wrong input $($entering characters, negative numbers, etc.$)$ your program needs to display message informing user of wrong input. For this assignment, you need to utilize the function to carry out calculation of the pay. Create a function called CalPay $($hrs$,$ rate$)$ which will take two arguments and return pay amount. Hourly rate and number of hours worked can be integers or floating point numbers.
