Looking at the example here: https://golang.org/doc/effective_go.html it looks like there's very little difference. In Go, you have to declare the return type(s) of the function, which Python doesn't require, but the caller treats the function the same. The Go example is: func nextInt(b []byte, i int) (int, int) { for ; i < len(b) && !isDigit(b[i]); i++ { } x := 0 for ; i < len(b) && isDigit(b[i]); i++ { x = x*10 + int(b[i]) - '0' } return x, i } which the caller uses like this: x, i = nextInt(b, i) In Python, we would write exactly the same thing: inside the nextInt function, we'd return multiple values: return x, i and the caller would accept them like this: x, i = nextInt(b, i) So the syntax is even the same. How is Go different from Python? -- Steve _______________________________________________ Python-ideas mailing list [email protected] https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
