Understanding Python If Statements

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

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

• if (condition) { code }

• if condition { code }

• if: condition then code

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: do_something; else: do_something_else

What will be the output of the following code: if x > 10: print('Greater') else: print('Lesser')?

• Equal

• Less than 10

• Greater than 10

• Lesser

Explain the purpose of the if-elif-else structure in Python.

• The purpose of the if-elif-else structure in Python is to control the flow of execution based on conditional statements.

• To handle exceptions in Python.

• To define functions in Python.

• To create loops in Python.

How do you write a conditional expression in Python?

• condition ? value_if_true : value_if_false

• value_if_true if condition else value_if_false

• if condition then value_if_true else value_if_false

• value_if_false unless condition then value_if_true

What is the output of this code: x = 5; result = 'High' if x > 10 else 'Low'; print(result)?

• Critical

• Low

• Medium

• Very High

Can you nest if statements in Python? Provide an example.

• Example: number = 10 if number > 0: if number % 2 == 0: print('Positive even number') else: print('Positive odd number') else: print('Non-positive number')

• Nesting if statements is only allowed in Java.

• If statements can only be used once in a program.

• You cannot use if statements in Python.

What is the difference between if-else and if-elif-else?

• if-else can handle multiple outcomes, while if-elif-else handles two conditions.

• if-else is used for loops, while if-elif-else is for conditional statements.

• The difference is that 'if-else' handles two outcomes, while 'if-elif-else' can handle multiple conditions.

• if-else requires a boolean expression, while if-elif-else does not.

How can you use logical operators in an if statement?

• You must use logical operators outside of if statements.

• You can use logical operators like '&&', '||', and '!' in an if statement to combine conditions.

• You can only use arithmetic operators in an if statement.

• Logical operators are not applicable in if statements.

What will happen if the condition in an if statement is false?

• The program will throw an error.

• The code inside the if statement is not executed.

• The code inside the if statement is executed.

• The if statement will be skipped entirely.
