COMP6010 Quiz & Flashcards: Python Comparison Operators

Study Notes

Equal operator: x == y checks if x is equal to y.
Not equal operator: x != y checks if x is not equal to y.
Greater than operator: x > y checks if x is greater than y.
Less than operator: x < y checks if x is less than y.
Greater than or equal to operator: x >= y checks if x is greater than or equal to y.
Less than or equal to operator: x <= y checks if x is less than or equal to y.
Boolean expressions can be used for comparisons, e.g., x < 8 yields True or False based on x's value.

Syntax: statement1 if condition else statement2.
Executes statement1 if the condition is True; otherwise executes statement2.
Provides a concise one-line alternative to traditional if-else structures.
Cannot use elif within inline if-else statements.
Example:
- For a = 5, b = 1 if a > 2 else 2 results in b being 1.

A year is considered a leap year if:
- It is divisible by 4 AND not divisible by 100, OR
- It is divisible by 400.
Example code checks for leap year:
- if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0):

Interest rates based on deposit amounts:
- $1 - $1,000: 1%
- $1,001 - $10,000: 1.5%
- $10,001 - $50,000: 1.8%
- $50,001 - $100,000: 2%
- Over $100,001: 2.5%
Example code demonstrates how to calculate interest based on the deposit amount.

Different tax rates apply based on income levels.
Base framework involves checking income against various thresholds to determine incremental tax rates.
Example check:
- If income is greater than $180,000, additional tax is calculated at 45% on the income exceeding $180,000.
