- Sets: Understand sets and their operations (union, intersection, difference).
- Control Flow
- Conditional Statements: Use
if
,elif
, andelse
to make decisions in your code. - Loops: Learn about
for
andwhile
loops for iterating over sequences. - Comprehensions: Use list and dictionary comprehensions for concise and readable code.
- Conditional Statements: Use
