支持可变长参数列表的函数可以支持任意个传入参数,比如fmt.Println函数就是一个支持可变长参数列表的函数. 需要注意的是,可变长参数应该是函数定义的最右边的参数,即最后一个参数 package main import "fmt" // 这个函数可以传入任意数量的整型参数 func sum(nums ...int) { fmt.Println(nums) total := 0 for i, num := range nums { fmt.Println(i) total += nu…
1. Python passes everything the same way, but calling it "by value" or "by reference" will not clear everything up, since Python's semantics are different than the languages for which those terms usually apply. If I was to describe it,…
