Teaching

1. Frequent mistakes

• WK1
  • not putting : (colon) after for loop
  • no indentation
  • misspelling range
• Other weeks
  • not putting : (colon) after if/while loop
  • using else with while
  • IndentationError

2. Frequent tips

• WK1
  • use _ instead of i
  • group indent by tabbing the block
  • write the rest of the function name automatically by pressing tab
  • delete repeating parts and fill for loop instead
  • copy-reuse the first four lines loading library (cs1robots) and world data (load_world, create_world, etc.)
• Other weeks
  • copy the code from other task and modify a very little bit
  • print statement to debug
  • ctrl + / to comment out a line
  • while True and break
  • tab and shift + tab to indent and unindent
  • Block indent by scrolling through multiple lines
  • ctrl + h to replace

3. Easy refactoring

• repetition -> for loop

  for i in range(5):
      # Your code here (repeated action)

• repetition -> function

  def my_function():
      # Your code here (repeated action)

• action ABABA -> halt in the middle of the last loop of for

  for i in range(3):
      # Your code here (repeated action)
      if i == 2:
          break
      # Rest of the code
