pythonwhat

Verify Python code submissions and auto-generate meaningful feedback messages. Originally developed for Python exercises on DataCamp for so-called Submission Correctness Tests, but can also be used independently.

Installation

# latest stable version from PyPi
pip install pythonwhat

# latest development version from GitHub
pip install git+https://github.com/datacamp/pythonwhat

Demo

To experiment locally, you can use setup_state() and write SCTs interactively. The code throws an error when the underlying checks fail.

# make all checking functions available
from pythonwhat.test_exercise import prep_context
_, ctxt = prep_context()
globals().update(ctxt)

# initialize state with student and solution submission
from pythonwhat.local import setup_state
setup_state(stu_code = "x = 5", sol_code = "x = 4")

Ex().check_object('x')
# No error: x is defined in both student and solution process

Ex().check_object('x').has_equal_value()
# TestFail: Did you correctly define the variable `x`? Expected `4`, but got `5`.

# Debugging state
Ex()._state               # access state object
dir(Ex()._state)          # list all elements available in the state object
Ex()._state.student_code  # access student_code of state object
