Resolved: Concering about the function named "def"

Question

I just want to ask what function def is and what does it do?

Answer 1

Hi John

I hope you're well

the word "def" in python is used to name your custom function. For example:

You want to create a function that multiplies a number by 2, so you write in your program

def multby2(int):

int * 2

then, when you want to use the function have to indicate for example:

multby2(5)

print(multby2(5))

and after the execution, you going to see the multiplication complete

10

I hope this could be help

Answer 2

I'm lost on this particular exercise...print (five(3)) equals 5? I don't know what the '3' is doing (how it affects anything) at all in this code. I guess I don't understand what the command 'print (five(3))' is supposed to do.

Answer 3

@Matt I think you will get how it works as you get to the functions part but in short, the 3 there is to show that no matter what input you pass (not just 3, it can be 49, 87 etc..), the function will just spit out five since the function does the job of assigning value "5" inside.
