Exercise 1.1 from your textbook recommends that you try to make mistakes when experimenting with a new programming feature.

This kind of experiment helps you remember what you read; it also helps when you are programming, because you get to know what the error messages mean. It is better to make mistakes now and on purpose than later and accidentally. (Downey, 2015, 7)

For this Learning Journal, first answer the following questions based on Exercise 1.1.

• If you are trying to print a string, what happens if you leave out one of the quotation marks, or both?
• You can use a minus sign to make a negative number like -2. What happens for each of the following?

>>> 2++2 >>> 2--2 >>> 2+-2 >>> 2-+2

• In math notation, leading zeros are OK, as in 02. What happens if you try this in Python?
• What happens if you have two values with no operator between them?

Next describe at least three additional Python experiments that you tried while learning Chapter 1. Show the Python inputs and their outputs, and explain what you learned from the results.
