Calculator Utilities

A basic calculator utility that provides fundamental arithmetic operations via a Python script.

How to Use

Run the calculator script with an operation and numbers:

python scripts/calculator.py <operation> <numbers...>

Operations

Add

Adds all numbers together.

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

python scripts/calculator.py add 10 20 30
# Output: 60

Subtract

Subtracts all subsequent numbers from the first number.

python scripts/calculator.py subtract 10 4
# Output: 6

python scripts/calculator.py subtract 100 25 15
# Output: 60

Multiply

Multiplies all numbers together.

python scripts/calculator.py multiply 6 7
# Output: 42

python scripts/calculator.py multiply 2 3 4
# Output: 24

Divide

Divides the first number by all subsequent numbers.

python scripts/calculator.py divide 20 4
# Output: 5.0

python scripts/calculator.py divide 100 2 5
# Output: 10.0

Error Handling

  • Division by zero: Returns an error message
  • Invalid input: Non-numeric values will show an error
  • Missing arguments: Shows usage instructions

Examples

# Simple addition
python scripts/calculator.py add 100 50
# Output: 150

# Chain subtraction
python scripts/calculator.py subtract 1000 250 150 100
# Output: 500

# Multiply decimals
python scripts/calculator.py multiply 3.14 2
# Output: 6.28

# Division with decimals
python scripts/calculator.py divide 22 7
# Output: 3.142857142857143
