python-calculator

A command-line calculator built in Python. Supports basic arithmetic operations.

How to run

Make sure you have Python 3 installed, then:

python calculator.py

Features

• Addition, subtraction, multiplication, division
• Division by zero handling
• Clears the screen between operations

Known issues

• Non-integer inputs (e.g. 2.5, abc) crash the program — try/except handling to be added
• Division results are truncated to integers (e.g. 7 / 2 returns 3 instead of 3.5)
• Invalid operation selections (e.g. 6, 7) cause a crash

Planned improvements

• Input validation with proper error handling
• Float support for both inputs and division results
• Additional operations (exponentiation, modulo)

Notes

First Python script. Built as part of a self-directed learning roadmap toward fintech development.
