• variables, functions, and files use snake_case
• classes use PascalCase
• indents are 4 spaces

• variables and classes should be nouns
• functions (including methods) should be verbs
• names should be descriptive. It's okay to make a name several words long if you need. For example, compute_conditional_probability() is WAY better than cp() or prob().

  A = Matrix(elements = [[1,2], [3,4]])
  B = A.copy()
  B.elements.append([5,6])
  B.num_rows += 1
  

  A = Matrix(elements = [[1,2], [3,4]])
  b_elements = A.elements
  b_elements.append([5,6])
  B = Matrix(elements = b_elements)
  

  poly_regress = PolynomialRegressor()
  poly_regress.ingest_data(sandwich_data)
  poly_regress.solve_coefficients(sandwich_situation = True)
  

  Do the analysis manually, without the class PolynomialRegressor.
  You can still use code from the class, but you should not actually modify the class.
  

  class Board(Player):
   ...

  (the Board is NOT a Player)
  

  class Board:
   ...
  

  def move():
   ...

  def movement():
   ...
  

  def move():

  def get_previous_movement():

  calc_median_or_mean(which="median")
  

  Use two different functions:

  calc_median()
  calc_mean()
  

  flips = ' '.join([''.join([['T','H'][round(random.random())] for _ in range(num_flips_per_sample)]) for _ in range(num_samples)]
  

  Break it up.

  flips = ''
  for _ in range(num_samples):
       sample = ''
       for _ in range(num_flips_per_sample):
            random_flip_is_heads = round(random.random())
            random_flip = ['H', 'T'][random_flip_is_heads]
            sample += random_flip
       flips += ' ' + sample"
  

  "combat_stats = {
       'attack': unit1_attack,
       'defense': unit1_defense,
       'opponent_attack': unit2_attack,
       'opponent_defense': unit2_defense
  }
  if combat_stats['attack'] > combat_stats['opponent_defense']:
       print('hit!')
  

  Use the object directly.

  if unit1.attack_strength > unit2_defense_strength:
       print('hit!')
  

  sample_stats = ['HHT', 2/3, 1/3]
  

  Use a dictionary:

  sample_stats = {
       'flips': 'HHT',
       'proportion_heads': 2/3,
       'proportion_tails': 1/3
  }
  

1. Create a new repl with the same name as the old repl
2. Connect the new repl to the existing github repository
3. Pull the github repository to your new repl
4. Copy any recent changes from your old repl to your new repl (i.e. just those changes that didn't get pushed up to github)
5. In your new repl, push the changes back up to your existing github repository
6. Your new repl is now fully up-to-date and connected to your github, so you can delete the old repl

1. Zip all your current code into a single zip file. You can do this by clicking on the three dots in the main heading of the "Files" panel and selecting "Download as zip".
2. Manually upload your zip file to Github. You can do this by going to your Github repository, clicking "Upload a file", dragging your zip file, and committing.
3. Create a new repl with the same name as the old repl.
4. Connect the new repl to the existing github repository.
5. Pull the github repository to your new repl.
6. In your new repl, unzip your zip file by typing unzip -o filename.zip into the command line. (You should replace "filename" with the actual file name of your zip file.)
7. Delete your zip file by typing rm filename.zip into the command line.
8. In your new repl, push your code back up to your existing github repository.
9. Your new repl is now fully up-to-date and connected to your github, so you can delete the old repl.
