Tricks and tips


Here are various coding tips I’ve seen while going through Python programming classes after installing Python and Juypter.

Also see Python REST API programming. Python Robot testing. Running Python on Raspberry Pi IoT devices.

Command generator

docopt at https://github.com/docopt/docopt and described at http://docopt.org/ creates custom CLI commands by parsing a command help text into cli code that implements it.



Dan Bader recommends the use of the

http://click.pocoo.org/6/why/ click custom package (from Armin Ronacher) instead of the argparse package that comes with Python 3.2+ (and the optparse package that comes with Python 2).

Click provides decorators such as the “@click.command()” below:

\# cli.py
import click

def main():
    print("I'm a beautiful CLI ✨")

if __name__ == "__main__":

List comprehension

squares = [x * x for x in range(10)]

[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
