Python In Practice - 15 Projects to Master Python - else Statements

The video tutorial explains the use of the else and pass keywords in programming. It demonstrates how the else keyword is used to execute code when a condition is false, particularly in discount calculations based on total value. The tutorial also covers the pass keyword, which allows for empty if statements without causing errors. Examples are provided to illustrate these concepts, showing how to control program flow and handle conditions effectively.

What is the primary purpose of using the 'else' keyword in programming?

• To define a function

• To execute a block of code when the 'if' condition is true

• To repeat a block of code multiple times

• To execute a block of code when the 'if' condition is false

In the context of the video, what happens if the total value is less than 1000?

• A 2% discount is applied

• A 10% discount is applied

• A 5% discount is applied

• No discount is applied

How does the 'else if' statement differ from the 'else' statement?

• 'else if' is used to define a loop

• 'else if' is the same as 'else'

• 'else if' executes when the 'if' condition is true

• 'else if' checks an additional condition, while 'else' does not

What is the role of the 'pass' keyword in a program?

• To leave a block of code empty without causing an error

• To execute a block of code

• To define a variable

• To terminate a loop

What error might occur if the 'pass' keyword is not used in an empty block?

• No error will occur

• Syntax error due to missing indentation

• Logical error in the program

• Runtime error due to missing variable
