Describe a function : Functions Part 2

The video tutorial discusses the concept of functions in programming, emphasizing the importance of returning values instead of printing them directly. It explains how returned values can be stored in variables for further manipulation, offering flexibility in their usage. The tutorial also covers best practices for writing functions, including maintaining proper indentation and structuring code blocks. By returning values, programmers gain more control and can perform various operations on the data. The video concludes with a brief mention of modules, setting the stage for the next tutorial.

Why is it generally better to return a value from a function rather than printing it directly?

• Printing is faster than returning a value.

• Returning a value allows for more flexibility in using the output.

• Returning a value is only useful for debugging.

• Printing is the only way to display output to the user.

What can you do with a value that has been returned from a function?

• Store it in a variable and manipulate it.

• Use it only once and then discard it.

• Only print it to the screen.

• It cannot be used outside the function.

How can you manipulate a returned string value in Python?

• By using string methods like upper() to change its case.

• By converting it to a number.

• By directly modifying the string in the function.

• By using it only as a constant value.

What is the significance of indentation in Python functions?

• Indentation is optional in Python functions.

• Indentation is used to denote the start of a new function.

• Indentation is used to define the block of code within a function.

• Indentation is only for improving code readability.

What is a key advantage of using functions in programming?

• They eliminate the need for variables.

• They make the code run faster.

• They allow for code reuse and better organization.

• They are only useful for small programs.
