Tips

  • Google and Stack Overflow are your friends. It’s not a shame to Google even really basic concepts. I have been programming for more than twenty years and i still Google really basic stuff every single day.
  • Your code should be properly commented (use #). Good commenting means you explain why you do something, not what you’re doing.
  • Keep your code DRY: Do not Repeat Yourself. If you copy-paste code, you probably could use a function instead.
  • Keep it tidy! Python is a language where indentation matters. This means that if you don’t format your code properly it won’t work.
  • Make sure you all your code is correctly spelled. Python is very picky! If you write If instead of if (note the capital) your code won’t work.
  • If you don’t understand why something isn’t working, try to make an example that is as simple as possible to pinpoint the cause.
  • Pay close attention to the error output you get when you run a command. Google it if you don’t understand it.
  • Note that Python is case sensitive and most file systems are too. When you create a new file only use lowercase characters, no spaces (use the underscore _ instead).
  • Read all the comments in the examples i provide. 90% of the things asked in the assignments are already solved for you there.
