Conditional Statements in Python

What is the purpose of using conditional statements in programming?

• To store data in a structured format.

• The purpose of using conditional statements in programming is to control the flow of execution based on certain conditions.

• To increase the speed of program execution.

• To simplify the code by removing unnecessary functions.

What is the basic structure of an if statement in Python?

• if condition: # code to execute if condition is true

• if (condition) { # code to execute }

• if condition then: # code to execute

• if: condition # code to execute if true

How do you write an if-else statement in Python?

• if condition: do_something; else do_something_else;

• if condition: do_something else: do_something_else

• if (condition) { do_something } else { do_something_else }

• if condition then do_something;

What does the elif keyword do in Python?

• The 'elif' keyword is used to define a function in Python.

• The 'elif' keyword is a way to create a new variable in Python.

• The 'elif' keyword allows for additional conditional checks in an if-else statement.

• The 'elif' keyword terminates a loop in Python.

Write a simple example of a nested if statement.

• if (number == 0) {('Zero'); }

• if (number < 0) {('Negative'); }

• if (number > 10) {('Greater than ten'); }

• if (number > 0) { if (number % 2 == 0) {('Even'); } else {('Odd'); } }

What will be the output of the following code: if x > 10: print('High') else: print('Low') when x is 5?

• Extreme

• Very High

• Low

• Medium

Explain the difference between if and if-else statements.

• The main difference is that 'if' only executes code when the condition is true, while 'if-else' provides an alternative action when the condition is false.

• 'If-else' statements are only used for loops and cannot handle conditions.

• Both 'if' and 'if-else' execute code only when the condition is false.

• 'If' statements can execute multiple blocks of code regardless of the condition.

What happens if no conditions are met in a series of if-elif statements?

• The program stops executing immediately.

• The program enters an infinite loop.

• The program continues to the next statement after the if-elif structure.

• An error message is displayed.

What is the output of the following code: if a == 10: print('Ten') elif a < 10: print('Less than ten') else: print('More than ten') when a is 10?

• No output

• More than ten

• Less than ten

• Ten

What is the result of using a condition that always evaluates to false in an if statement?

• The code inside the if block will execute.

• The code inside the if block will not execute.

• The program will terminate.

• An error will be raised.
