# can't understand function

I can't understand function and return .please tell me in brief about it .if somebody know tell me please.

STAFF

Hi there! I wrote a little example here to help explain:

```def multiply(x,y):
return x * y

result = multiply(7, 10)
print(result)
```

The function here is named `multiply` and it accepts two values. A function is simply a piece of code that we want to be run every time we call it. So in this simple example we have a a variable named result. We're going to call/invoke/execute the multiply function and we're going to send in a 7 and a 10. The values 7 and 10 will come into the function and we are now accessing them with the names `x` and `y`. We multiply them together and `return` the result. We're returning the value to the original piece that called it. Which is `multiply(7,10)`. This will now put 70 into the variable result. Now when we print the value of `result` to the screen, it will print 70.

Hope this helps!

thanks a lot i know you helped me one more time
