2.E: Variables, Expressions, and Statements (Exercises)

Exercise 2: Write a program that uses input to prompt a user for their name and then welcomes them.

Enter your name: Chuck
Hello Chuck

Exercise 3: Write a program to prompt the user for hours and rate per hour to compute gross pay.

Enter Hours: 35
Enter Rate: 2.75
Pay: 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 4: Assume that we execute the following assignment statements:

width = 17
height = 12.0

For each of the following expressions, write the value of the expression and the type (of the value of the expression).

  1. width//2

  2. width/2.0

  3. height/3

  4. 1 + 2 * 5

Use the Python interpreter to check your answers.

Exercise 5: Write a program which prompts the user for a Celsius temperature, convert the temperature to Fahrenheit, and print out the converted temperature.


  1. In Python 2.0, this function was named raw_input.

  2. See http://en.wikipedia.org/wiki/Mnemonic for an extended description of the word "mnemonic".
