Auto-grading for Coding the Matrix, Edition One (beta
Make sure you have Python 3.x on your computer. In the
following, I will assume that python3 is the command used
to invoke Python. (On Windows, it might be just python.)
Create a single directory, called matrix, in which you
will put all your code.
Download the submission script, submit.py,
to the matrix directory.
To get your work graded,
- download the appropriate stencil file into the matrix
- edit it to include answers to whichever problems you choose,
- make sure you can import it into Python without error,
- test your solutions, and
- finally submit problems from a given stencil by using the
following command from a console or shell or Command Prompt:
python3 submit.py <stencil filename>
For example, to submit solutions to problems appearing in the
chapter The Function, edit The_Function.py, and
then use the command
python3 submit.py The_Function.py
Note that these commands are executed not from within the Python
REPL, but within a console or shell or Command Prompt.
More about submit
The submit script asks for your username. This can be
anything you like. When you submit a correct answer, the script
stores a "receipt" in a subdirectory receipts of your matrix
directory, specifying your username, the data, and the identifier of
the problem you solved.
To avoid having to give your username each time you run the submit
script, you can create a file profile.txt in your matrix
directory with the following line in it:
where "philipklein" is replaced with your chosen username. Later I
will write about other features of the submit script. In
particular, we plan to have a leaderboard; you will be able to
request that your successful submits be reported to the leaderboard.
The Stencil files
More stencil files will be added as I complete them. Note that
these are still rough and should be considered beta versions.
