Python function return value instance analysis

The example in this article describes the function return value usage of Python. Share to everyone for your reference. The specific analysis is as follows:

Recently learn some of the basic usage of Python, see the definition function, found that it seems to return only a return value, think of the MATLAB return multiple return value more convenient Ah, on-line check, see there is a way to return multiple values.

The return value of a Python function has two forms:

1 returns a value.
2 returns multiple values.

Now take a look at the return value of the bar.

def firstvalue (b): c = a + B return cprint firstvalue (#结果): 3

And look at the return of multiple values: How can I return multiple values, other languages generally call the function, you can only return a value, maybe I am not familiar with all the language, I know the language can only return a value, and Python can return multiple values, it is very convenient to send code to look at:

def secondvalue (b): c = a + B return (a,b,c) x, y, z = secondvalue (in) print ' ×: ', X, ' y: ', y, ' z: ', Z

Hopefully this article will help you with Python programming.
