Understanding If-Else Statements in Python

What is the purpose of an `if` statement in Python?

• To repeat a block of code multiple times

• To execute a block of code only if a specified condition is true

• To define a function

• To import a module

Consider the following code snippet: ```python x = 10 if x > 5: print("Greater than 5") else: print("5 or less") ``` What will be the output of this code?

• Greater than 5

• 5 or less

• Error

• No output

Which of the following keywords is used to check multiple expressions in Python?

• switch

• elif

• case

• loop

Given the code snippet below, what will be the output? ```python x = 3 if x == 5: print("Five") elif x == 3: print("Three") else: print("Other") ```

• Five

• Three

• Other

• Error

What is the correct syntax for an `if` statement in Python?

• if x > 5 then:

• if (x > 5):

• if x > 5:

• if x > 5;

Consider the following code: ```python x = 7 if x < 5: print("Less than 5") elif x < 10: print("Less than 10") else: print("10 or more") ``` What will be the output?

• Less than 5

• Less than 10

• 10 or more

• Error

Which of the following is true about `else` in Python?

• It must be used with every `if` statement

• It is optional and provides an alternative block of code if the `if` condition is false

• It can only be used once in a program

• It is used to end a loop

What will be the output of the following code? ```python x = 15 if x < 10: print("Small") elif x < 20: print("Medium") else: print("Large") ```

• Small

• Medium

• Large

• Error

Which of the following statements is true about `elif` in Python?

• It is used to end a function

• It allows checking multiple expressions for true and executes a block of code as soon as one of the conditions is true

• It is used to start a loop

• It is used to import libraries

Analyze the following code and determine the output: ```python x = 20 if x < 10: print("Below 10") elif x < 30: print("Below 30") else: print("30 or above") ```

• Below 10

• Below 30

• 30 or above

• Error
