Parsing Command-Line Argument in Python

Command-line arguments in Python show up in sys.argv as a list of strings (so you'll need to import the sys module).

For example, if you want to print all passed command-line arguments:

import sys
print(sys.argv)  # Note the first argument is always the script filename.

Command-line options are sometimes passed by position (e.g. myprogram foo bar) and sometimes by using a "-name value" pair (e.g. myprogram -a foo -b bar).

Documentation-Driven Development (DDD)

Documentation-Driven Development

The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.

  • Document the feature first. Figure out how you're going to describe the feature to users; if it's not documented, it doesn't exist. Documentation is the best way to define a feature in a user's eyes.
  • Whenever possible, documentation should be reviewed by users (community or Spark Elite) before any development begins.
  • Once documentation has been written, development should commence, and test-driven development is preferred.
  • Unit tests should be written that test the features as described by the documentation. If the functionality ever comes out of alignment with the documentation, tests should fail.
  • When a feature is being modified, it should be modified documentation-first.
  • When documentation is modified, so should be the tests.

How to squash commits in git

Squashing Git Commits

The easy and flexible way

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).

Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.

Switch to the master branch and make sure you are up to date:
