Python 🐍 If Statements

The video tutorial covers the use of if, else, and elif statements in Python programming. It explains how these conditional statements control the flow of a program and provides examples such as a calculator and a temperature control system. The tutorial also includes a guessing game using random LED values and demonstrates how to apply these concepts in a course project.

What is the primary purpose of an if statement in programming?

• To declare a variable

• To execute a block of code based on a condition

• To define a function

• To repeat a block of code multiple times

In the context of if statements, what does the term 'condition' refer to?

• A function that returns a value

• A boolean expression that determines the flow of execution

• A statement that always evaluates to true

• A loop that runs indefinitely

What is the role of an else statement in a conditional structure?

• To execute code when the if condition is true

• To execute code when the if condition is false

• To repeat the if condition

• To terminate the program

How does an elif statement differ from an else statement?

• Elif is used to define a function

• Elif repeats the previous condition

• Elif terminates the program

• Elif provides an additional condition to check

What operation does the calculator perform when the user selects 'addition'?

• Multiplies the two numbers

• Adds the two numbers

• Subtracts the second number from the first

• Divides the first number by the second

In the LED control program, what happens when the temperature exceeds 35 degrees Celsius?

• The LED turns off and the kit disconnects

• The program restarts

• The LED blinks rapidly

• The LED turns on

What is the purpose of using a while loop in the LED control program?

• To execute the code a fixed number of times

• To initialize variables

• To define a new function

• To continuously check and respond to temperature changes

In the guessing game, what feedback does the program provide if the user's guess is too high?

• It prints 'Correct!'

• It prints 'Too low'

• It restarts the game

• It prints 'Too high'

What happens when the user correctly guesses the LED intensity in the guessing game?

• The LED changes color

• The LED turns off

• The LED flashes for a few seconds

• The program terminates immediately

What is the range of random LED intensity values in the guessing game?

• 10 to 90

• 5 to 95

• 1 to 100

• 0 to 50
