CISC108 0.4

CISC108 Support Library

A collection of tools to help students write code.

For now, mostly improved assertions.

Installation

Install from PyPi:

pip install cisc108

Or install from the https://github.com/UD-CIS-Teaching/cisc108-python-support-library

Examples

from cisc108 import assert_equal

def halve(number):
    return number / 2

# Correctly handles floating points
assert_equal(halve(10), 5.0)

Output

This library will print a message to STDOUT if an assertion fails, and returns True/False. It does not raise an exception or print to STDERR.

Supported Types

• Numbers: strictly compares numeric types, but allows floats to have imprecision, defaults to 4 places

• Strings: can strictly compare types with exact_strings=True, but defaults to ignore whitespace on newlines and capitalization

• Lists, Tuples: applies same rules to inner types as container types

• Sets, Frozensets, Dictionary: checks that all elements are contained in both, in any order

• Generators: functions like enumerate and .items() that produce generators are converted to lists and sets (as appropriate), then checked that their values match.

• Other types should work as well, but require that the result of type match, and that x == y
