Here's how to build your codecheck challenge solution as a CLI application.

• Python3 (For the version see our docs .)
• The standard library's argparse module

In app/app.py is a function called main. Build your console application there.

def main(args, options):
  for arg in args:
    # Replace below line with your code.
    result = arg

All stdin input arguments are passed into args as an array.

If you want to use optional arguments, add them using argparse's parser.add_argument in cli.py

Use the standard print() method to output results to stdout.

  print(result)

If you want to use external libraries, do the following:

• Write the library name and version in requirements.txt
• Add the following to codecheck.yml:

build:
  - pip3 install -r requirements.txt
