REST APIs with Flask and Python - If Statements

This video tutorial covers the basics of using if statements in Python, including how to implement them with Boolean values and user input. It explains the importance of indentation in Python and introduces the else and elif statements for branching logic. The tutorial also addresses handling user input, particularly focusing on case sensitivity and how to standardize input using string methods. By the end of the video, viewers will understand how to use if statements effectively in Python programming.

What is the primary purpose of using an if statement in a program?

• To define a new function

• To make decisions based on Boolean values

• To repeat a block of code multiple times

• To import external libraries

In Python, what is the significance of indentation in an if statement?

• It is used to comment the code

• It is optional and has no effect

• It determines the order of execution

• It indicates which code belongs to the if block

What happens if you do not use consistent indentation in Python?

• The code will run faster

• The code may not work correctly

• The code will be more readable

• The code will automatically correct itself

What is the role of the else statement in Python?

• To execute code when the if condition is false

• To import a module

• To execute code when the if condition is true

• To define a new variable

How does the elif statement enhance the functionality of if statements?

• By allowing multiple conditions to be checked sequentially

• By repeating the same condition

• By terminating the program

• By defining a new class

Why is it important to handle user input variations in Python programs?

• To reduce the number of lines of code

• To ensure the program runs faster

• To make the code more readable

• To handle different input cases consistently

What method can be used to convert a string to lowercase in Python?

• lower()

• convertLower()

• makeLower()

• toLower()
