Python Conditionals Worksheet

What are the main conditional statements used in Python?

• if, elif, and else

• switch, case, and default

• when, then, and otherwise

• for, while, and do-while

What is the purpose of comparison operators in conditional statements?

• To evaluate conditions using operators like >, <, and ==.

• To perform arithmetic calculations in code.

• To define variables in a program.

• To print output to the console.

What should be considered when handling conditional statements for a number’s value?

• All possible cases: positive, negative, and zero.

• Only the positive case.

• Only the negative case.

• Only the zero case.

Why is indentation important in Python conditionals?

• It defines the scope of code blocks under conditionals.

• It makes the code run faster.

• It is only for visual appeal.

• It is required only for comments.

What role does else play in conditional statements?

• It acts as a catch-all for unexpected inputs.

• It always executes before the if block.

• It is used to repeat a block of code.

• It defines a new variable.

What is the purpose of the and operator in conditions?

• To combine two conditions, such as checking an age range.

• To end a program.

• To repeat a block of code.

• To assign a value to a variable.

What does the modulo operator (%) check for in conditions?

• It checks for divisibility, such as x % 2 == 0.

• It checks for equality between two numbers.

• It checks for the largest value in a set.

• It checks for the presence of a decimal value.

What is the significance of clear output messages in conditionals?

• They enhance user understanding of the program’s logic.

• They slow down the execution of the program.

• They make the code harder to debug.

• They increase the memory usage significantly.

What is the relationship between boolean expressions and truth values?

• Boolean expressions evaluate to 'True' or 'False'.

• Boolean expressions always result in numbers.

• Boolean expressions are unrelated to truth values.

• Boolean expressions only evaluate to 'True'.

What are multi-branch conditionals in programming?

• They are structures that use 'if', 'elif', and 'else' to handle multiple outcomes based on conditions.

• They are loops that repeat a block of code multiple times.

• They are functions that return multiple values at once.

• They are variables that can store multiple data types.
