It's my first python mini-project, not a normal calculator program. It can evaluate as many as long expressions and user can also perform operations on output result as in real calc.
Basic programming in python.
Used re module for regular-expressions(regex) for handling anonymous inputs by user and evaluating the expressions entered.
Just download the zip file and extract it to some location/folder. Open command prompt/terminal and run the python file
pyhton3 calcProject.py
