RealFractions

Python library who adds functions related to the operation and conversion of fractions in a string format, with specific classes depending on what needs to be done.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Make sure you have Python and that the expected version is available from your command line. You can check this by running:

python --version

You should get some output like Python 3.6.3. If you do not have Python, please install the latest 3.x version from python.org

Additionally, you’ll need to make sure you have pip available. You can check this by running:

pip --version

If you installed Python from source, with an installer from python.org you should already have pip. If you’re on Linux and installed using your OS package manager, you may have to install pip separately, see Installing pip/setuptools/wheel with Linux Package Managers.

If pip isn’t already installed, then first try to bootstrap it from the standard library:

python -m ensurepip --default-pip

While pip alone is sufficient to install from pre-built binary archives, up to date copies of the setuptools and wheel projects are useful to ensure you can also install from source archives:

python -m pip install --upgrade pip setuptools wheel

Installing

To install the latest version of RealFractions:

pip install -U real-fractions

And then you can import this library in Python:

from real_fractions import convert

fraction = "1/2"
fraction = to_decimal(fraction)

print(string)
# Output: 0.5

Or you can check the project in PyPI.

Running the tests

To run automated module tests you first need to install py.test:

pip install -U py.test

Then you must to download the source code of the module in his github repository, go to the tests folder with PowerShell and run pytest:

pytest

Some test examples

These are some examples of the automated test

    def test_simplify(self):
        """Test simplify method from Fractions."""

        # Normal cases
        assert self.simplify("5/10") == "1/2"
        assert self.simplify("-12/4") == "-3/1"
        assert self.simplify("10/-2") == "-5/1"
        assert self.simplify("-20/-2") == "10/1"

        # Invalid arguments
        assert self.simplify("10/0") is None
        assert self.simplify(True) is None
        assert self.simplify("Error") is None

This test is testing all the general cases of the function simplify of the core module.

Acknowledgments

This is my second package that I publish as open source, it was a project that I proposed as a challenge to practice programming, I am still a junior programmer but I tried to do my best. Thanks anyway for getting here, a kiss.
