Knowledge
Loops are fundamental constructs in programming that allow for the execution of a block of code multiple times based on certain conditions. This chapter covers two primary types of loops in Python: 'for' loops, which iterate over sequences, and 'while' loops, which continue until a specified condition becomes false. Additionally, control statements like break, continue, and pass are discussed to manage loop behavior more effectively.

What we have learnt
- Loops enable code execution multiple times based on conditions.
- For loops are used for iterating over sequences.
- While loops repeat code block execution while a condition is true.
- Control statements break, continue, and pass manage loop execution.
- Nested loops allow for complex iteration scenarios.
Key Concepts
-
Term: Loop
Definition: A programming construct that repeats a segment of code multiple times.
-
Term: For Loop
Definition: A loop that iterates over a sequence like lists, strings, or ranges.
-
Term: While Loop
Definition: A loop that continues execution as long as a specified condition evaluates to true.
-
Term: Break
Definition: A control statement that exits a loop immediately.
-
Term: Continue
Definition: A control statement that skips the current iteration and continues with the next.
-
Term: Pass
Definition: A placeholder statement indicating that nothing happens; often used as a temporary measure.
-
Term: Nested Loop
Definition: A loop that exists inside another loop, allowing for multi-level iteration.
