What is a function in the context of programming?

A sequence of statements that performs a computation (correct)
A sub-task that cannot be reused
A named sequence of statements that performs a debug
A block of code that executes automatically

Why is it beneficial to divide a larger problem into sub tasks?

It makes debugging harder
It makes the code longer
It saves development time and efforts (correct)
It cannot be done

What is a characteristic of a user-defined function?

It is defined by the user in their program (correct)
It is already defined in Python libraries
It is a type of built-in function
It can only be used once
