In this course, you will be marked not only on whether your code works, but also on style. Here are some guidelines:
Use Python style conventions for your function and variable names (pothole case: lowercase letters with words separated by underscores (_) to improve readability).
Choose good names for your functions and variables. For
example, num_bright_spots is more helpful and
readable than nbs.
Use a tab width of 4 (Wingware's default), if you use tabs at all. The best way to make sure your program will be formatted correctly is never to mix spaces and tabs -- use only tabs, or only spaces.
Put a blank space before and after every operator. For example, the first line below is good but the second line is not:
b = 3 > x and 4 - 5 < 32
b= 3>x and 4-5<32
Write a docstring comment for each function.
Your function comments must mention what, if anything, the function returns, and the purpose of each parameter. The comment must be grammatically correct.
Put a blank line after every docstring comment.
Each line must be less than 80 characters long
including tabs and spaces. You should break up long
lines using \.
In Wing, you can find out what column you are in by looking in the lower left-hand corner.
Complicated bits of code inside functions should have comments describing their purpose. For example, a loop that swaps the red and blue values in the pixels of a picture might have this as a comment:
# Swap the values of the red and blue components of every pixel.
