The *args and **kwargs is a common idiom to allow arbitrary number of arguments to functions as described in the section more on defining functions in the Python documentation. The *args will give you all function parameters as a tuple: def foo(*args): for a in args: print(a) foo(1) # 1 foo(1,2,3) # 1 # 2 … Read more
You can use a vararg syntax similar to C: package main import “fmt” func my_func( args …int) int { sum := 0 for _,v := range args { sum = sum + v } return sum; } func main() { arr := []int{2,4} sum := my_func(arr…) fmt.Println(“Sum is “, sum) } Now you can sum … Read more
The single star * unpacks the sequence/collection into positional arguments, so you can do this: def sum(a, b): return a + b values = (1, 2) s = sum(*values) This will unpack the tuple so that it actually executes as: s = sum(1, 2) The double star ** does the same, only using a dictionary … Read more
