What are Conditionals?
In programming, conditionals allow your code to make decisions and execute different instructions depending on whether a condition is True or False.
Real-world analogy
Imagine waking up in the morning: "If it is raining outside, take an umbrella. Else, wear sunglasses." Your brain evaluates the weather condition and chooses one path. That is exactly what conditional branching does in Python!
🔀
Branching Logic
Directs program execution down different code paths based on rules.
🎯
Decision Making
Enables your app to respond dynamically to user input and changing data.
🚦
Control Flow
Controls which lines of code run and which lines are skipped entirely.
🧠
Smart Apps
Powers game rules, login validation, grade checkers, and AI decisions.
Key vocabulary
- Boolean Expression — a statement that evaluates to either
TrueorFalse. - Branch — a block of code executed only when its corresponding condition is met.
- Indentation — 4 spaces used in Python to group statements inside a conditional block.
