A command line program that takes a string of whole and mixed numbers and returns the mathematical result.

Write a command line program in the language of your choice that will take operations on fractions as an input and produce a fractional result.

• Legal operators are be *, /, +, - (multiply, divide, add, subtract)

• Operands and operators shall be separated by one or more spaces

• Mixed numbers will be represented by whole_numerator/denominator. e.g. "3_1/4"

• Improper fractions and whole numbers are also allowed as operands

Example run:

? 1/2 * 3_3/4

= 1_7/8

? 2_3/8 + 9/8

= 3_1/2

• Clone repo
• Create a virtual environment

virtualenv <name of venv>

• Activate the fresh environment (linux)

source <name of venv>/bin/activate

• Run setup.py from Python 3+

python3 setup.py install

• Install package via symlink for dev code

pip install -e .

python3 main.py

Tests can be performed two ways.

One:

python3 tests/frac_tests.py

Two: Run the script

python3 main.py

and in the prompt, enter tests

# Command Prompt
Enter a command: tests

• Make compatible with parenthesis
