18: Parameters in python

Debug it

Parameters: Adapt and reuse sections of your code

Below is some code that has been deliberately broken so that you can fix it. 

The code is supposed to draw a snowman with an orange nose and two eyes:

Challenges

  1. Fix the syntax errors

    Hint: parameters need be surrounded by brackets and separated by commas

  2. Change the nose to orange

    Hint: This is a logic error. The code runs (so it can’t be a syntax error) and doesn’t crash (so it’s not a runtime error). 

  3. Add the missing eye so it’s symmetrical

    Hint: The coordinates (0,0) are in the middle. Positive coordinates go left and up from the middle.
