Developments

The code style of python package follows pep8. If you would like to make a contribution and not familiar with pep-8, please check the pep8 style guide first. Otherwise, you won't pass the check. You should be careful about:

  • E1 Indentation (check pep8 link above)
  • E202 whitespace before and after brackets
  • E225 missing whitespace around operator
  • E226 missing whitespace around arithmetic operator
  • E261 at least two spaces before inline comment
  • E301 expected 1 blank line in front of and at the end of a method
  • E302 expected 2 blank lines in front of and at the end of a function or a class

You can ignore E501 (line too long).
