Study Notes
- Math operations like subtraction, multiplication, and division can be performed in Python.
Basic Math Functions in Python:
- Addition:
c = a + b - Subtraction:
c = a - b - Multiplication:
c = a * b - Division:
c = a / b
Math Examples:
- Arithmetic can be performed directly within the print statement.
- When dividing integers, the result is a float.
Order of Operations:
- Describes the specific sequence for executing math statements.
- The order is: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
- Using the correct order of operations is important for accurate calculations.
Clarity and Readability:
- Consistent spacing and logical code organization enhance readability.
- Variables should have names that clearly indicate their purpose.
- Clarity and readability are important when expressing algorithms in code.
