Instructions

Welcome to your first set of exercises! This is your chance to put your knowledge into practice.

If you haven't yet learned how to use a Python panel or about the exercises, take a moment to do so now.

Here are the instructions:

What is the result when you run the program print(5)?

Run the code in the Python panel to see the answer.

Note:

Hints:

  • undefined

What about this program? Try to figure out the answer before pressing the Run button.

Note:

The computer is telling you that the word you used is not defined; the name print should be written in lower-case letters.

To help avoid such messages, we've provided you with a list of built-in functions. If you do see one, we've also provided you with a list of common error messages.

Hints:

  • undefined

Now fix the error and run the program again.

Note:

Did you notice how the colour of the word changed once it was written correctly?

Hints:

  • undefined

What do you think will happen if there is a missing right parenthesis? Try to figure it out, and then without making any changes to the code, click the Run button.

Note:

Take a good look at the error message so that if you see it again, you'll know what it means. "EOF" stands for "end of file". This means that the program ended before the print instruction was completed.

Hints:

  • undefined

Guess the result, then click the Run button.

Note:

This was a tricky one: you might have been trying to remember that division always produces a floating point number, which is correct.

What is not correct is the symbol used to show division. The correct symbol to use is /, not the backslash. We've provided you with a handy list of built-in functions.

Don't worry about understanding the error message. In case you're curious, here's what it means. The backslash is used at the very end of a line to show that information continues onto the next line. The term continuation character refers to the backslash. The computer is complaining that it found a character after what was supposed to be the very last character on the line.

Hints:

  • undefined

Fix the error and run the code before continuing.

Note:

Hint:

  • Use the forward slash for division.

Fix this program so that it will print the volume (in cubic centimetres) of a box that is 50 centimetres wide, 100 centimetres long, and 10 centimetres tall.

Note:

Hint:

  • Make sure that you use the correct symbol for multiplication. You can look it up in the list of built-in functions if you've forgotten what it is.

The square root of a number can be computed by taking the number to the power 0.5. Write a program that prints the square root of 365.

Note:

Hints:

  • Use ** to determine an exponent. Remember that the first number is the base and the second number is the exponent.

In curling, there are four people on a team. All 145,211 people in Prince Edward Island would like to play. Write a program to figure out how many complete teams there can be. No one is allowed to be on more than one team, but it is acceptable (although disappointing) for someone not to be on any team.

Note:

Hints:

Now modify your program to determine the number of people who do not end up being able to play.

Note:

Hint:

  • Try using the remainder operation.

This program is supposed to calculate the number of months in 5+12 years. Does it work correctly? If not, add parentheses as needed.

If you need to review the precedence rules, you might rewatch Step 3.

Note:

Hints:

  • undefined

Add as many pairs of parentheses as you need to make the value as large as possible.

Note:

Hint:

  • Think about the precedence rules: you don't have to try all possibilities.

Add as many pairs of parentheses as you need to make the value as small as possible.

Note:

Hint:

  • Think about the precedence rules: you don't have to try all possibilities.
