CMU CS Academy Unit 2 Part 1 Functions

What is the primary purpose of using functions in programming?

• To repeat code for every action needed

• To create mini-programs that can be reused

• To avoid using loops in the code

• To make the code longer and more complex

What keyword is used in Python to define a function?

• define

• function

• def

• func

What is the purpose of parameters in a function?

• To give a unique name to each function

• To provide input values that the function uses

• To determine the return type of the function

• To specify the number of times a function should run

What does the 'def' keyword in Python indicate?

• The end of a function

• The start of a default statement

• The definition of a new variable

• The definition of a new function

What is the significance of indentation in Python functions?

• It makes the code look cleaner

• It is optional and has no real use

• It increases the execution speed of the function

• It is used to define the body of the function

How do you call a function in Python?

• By declaring the function name at the beginning of the code

• Functions in Python are called automatically

• By simply writing the function name followed by parentheses

• Using the call keyword followed by the function name

What is the difference between a parameter and an argument in a function?

• Parameters are used to define functions, while arguments are used in function calls

• Arguments are used to define functions, while parameters are used in function calls

• Parameters and arguments are the same in Python

• Parameters are optional, but arguments are mandatory

Why is case sensitivity important in naming functions in Python?

• It is not important; Python is not case-sensitive

• Python treats uppercase and lowercase letters as different characters

• It helps in distinguishing different functions

• It affects the function's performance

What happens if you use a reserved keyword as a function name in Python?

• Python will ignore the function definition

• The function will override the keyword's original use

• An error will occur because reserved keywords have predefined meanings

• The code will execute without issues

Why is it important to avoid using common Python keywords as function names?

• To prevent syntax errors

• To improve code readability

• To avoid overloading the function

• To prevent conflicts with Python's predefined meanings for those keywords
