Exercise 2.3 Write a program to prompt the user for hours and rate per hour to compute gross pay.
Enter Hours: 35Enter Rate: 2.75Pay: 96.25
We won’t worry about making sure our pay has exactly two digits after the decimal place for now. If you want, you can play with the built-in Python round function to properly round the resulting pay to two decimal places.
Exercise 2.4 Assume that we execute the following assignment statements:
width = 17height = 12.0
For each of the following expressions, write the value of the expression and the type (of the value of the expression).
width/2width/2.0height/31 + 2 * 5
Use the Python interpreter to check your answers.
Exercise 2.5 Write a program which prompts the user for a Celsius temperature, convert the temperature to Fahrenheit and print out the converted temperature.
