4.8Summary
What we have learnt
- if is used to run a block of code when a condition is True.
- elif checks other conditions if the first is False.
- else runs when all if and elif conditions are False.
- Indentation defines the block of code that will be executed.
- Nested if statements allow for complex decisions.
Key Concepts
- -- Control Flow
- The mechanism by which a program makes decisions and executes blocks of code based on conditions.
- -- if Statement
- A statement that executes a block of code only if a specified condition is True.
- -- elif Statement
- A statement that allows checking multiple conditions; short for 'else if'.
- -- else Statement
- A statement that executes a block of code when the if condition is False.
- -- Indentation
- The use of spaces or tabs to define code blocks in Python.
- -- Nested Conditions
- The practice of placing an if statement inside another if statement to create more complex decision structures.
