Understanding Functions in Python

The video tutorial introduces the concept of functions in Python, explaining their purpose and how they make code modular. It covers the syntax of if statements and special variables like '__name__'. The tutorial then demonstrates creating a simple function named 'greet' that prints 'Hello World', including how to call this function. The video emphasizes the importance of indentation and the absence of parameters in this example. The tutorial concludes by running the code to show the output.

What is the primary purpose of functions in programming?

• To make code less readable

• To increase the execution time

• To make code more complex

• To organize and reuse code

What does the special variable '__name__' represent in a Python script?

• The name of the main program

• The name of the module

• The name of the last function

• The name of the first function

When is the '__name__' variable set to '__main__'?

• When the script is compiled

• When the script is imported

• When the script is executed directly

• When the script is saved

What is the benefit of encapsulating the main function in a Python program?

• It makes the code less readable

• It allows for more complex code

• It enhances code modularity

• It increases the file size

What is the first step in creating a function in Python?

• Importing the function

• Defining the function

• Deleting the function

• Calling the function

What is the purpose of indentation in Python functions?

• To increase execution speed

• To make the code look neat

• To indicate the end of a function

• To define the scope of the function

What will happen if a function is defined but not called in a Python script?

• The function will cause an error

• The function will execute automatically

• The function will not execute

• The function will delete itself

What is the output of the 'greet' function when it is called?

• Goodbye World

• Hello Universe

• Hello World

• Greetings Earth

What is the correct syntax to call a function named 'greet' in Python?

• execute greet()

• call greet()

• run greet()

• greet()

What will be the output if the 'greet' function is called twice in a script?

• Greetings Earth Greetings Earth

• Hello Universe Hello Universe

• Hello World Hello World

• Goodbye World Goodbye World
