Deep Learning - Computer Vision for Beginners Using PyTorch - Conditional Statements in Python - if

The video tutorial covers conditional statements in Python, focusing on if, if-else, and elif structures. It explains how these statements control the flow of a program by evaluating conditions and executing code blocks accordingly. Examples demonstrate the use of these statements, including nested conditions and the impact of indentation. The tutorial emphasizes the importance of understanding control flow for decision-making in programming.

What is the primary purpose of control flow statements in Python?

• To simplify syntax

• To make code run faster

• To enable decision-making in programs

• To execute statements in a random order

Which keyword is used to start an if statement in Python?

• check

• when

• if

• condition

What happens if the condition in an if statement is true?

• The if block is executed

• The program stops

• The condition is ignored

• The else block is executed

In the given example, what is printed if NUM is 50?

• No output

• Number is larger than 100

• Number is equal to 100

• Number is smaller than 100

What is the output when the condition in an if statement is false and there is no else block?

• The if block is executed

• No output is produced

• The program prints an error

• The program crashes

What is the purpose of nesting if statements?

• To avoid using else

• To reduce execution time

• To check multiple conditions

• To make code more complex

How does the elif keyword improve code readability?

• By reducing the need for nested if statements

• By adding more conditions

• By making code run faster

• By increasing indentation

What is the output if NUM is 75 in the nested if example?

• Number is between 50 and 100

• Number is less than 50

• No output

• Number is greater than 100

Which statement is used to handle multiple conditions in a more readable way?

• case

• elif

• else

• switch

What is the result of using elif instead of nested if statements?

• Increased complexity

• More conditions can be checked

• Simplified code structure

• Faster execution
