integer-calculator

Calculate addition, subtraction, multiplication and division of two integers via a Python script.

This skill calculates the addition, subtraction, multiplication or division of two integers by calling a local Python script.

Usage

When the user asks to perform arithmetic on two integers, run the following command:

bash

python3 scripts/calculator.py   

Parameters

Parameter	Type	Required	Description
num1	int	Yes	First integer
num2	int	Yes	Second integer
operation	string	Yes	add, sub, mul, div

Examples

Addition:

bash

python3 scripts/calculator.py 3 5 add
# Output: 8

Subtraction:

bash

python3 scripts/calculator.py 10 4 sub
# Output: 6

Multiplication:

bash

python3 scripts/calculator.py 3 5 mul
# Output: 15

Division:

bash

python3 scripts/calculator.py 10 4 div
# Output: 2.5

Notes

• Supported operations: add, sub, mul, div.
• Both inputs must be valid integers.
• Division returns a float result; dividing by zero will return an error message to stderr and exit with code 1.
• The script prints only the numeric result to stdout for easy parsing.
