I want to understand the below code snippet from Python :

name, *line=input().split()
scores=list(map(float, line))

I understand input(), split(), map functions. I would like someone to explain me how the assignment name, *line work here and then how variable line is used in subsequent expression.

The `*` has nothing to do with pointers. – user2357112 Apr 25 '17 at 18:34
@user2357112 : So can you please elaborate concept is it . – Ritesh Apr 25 '17 at 18:35

`str.split` could produce more than one value. `name, *line = input().split()` unpacks the first value into `name` and the rest into `line`. – Peter Wood Apr 25 '17 at 18:35

@PeterWood so would `line` be an array, or automatically rejoined? – Fallenreaper Apr 25 '17 at 18:38

@Fallenreaper try it (c: It's a `list`. – Peter Wood Apr 25 '17 at 18:41
@PeterWood yeah, it is. That's neat. Sometimes I learn more just from reading comments. – Fallenreaper Apr 25 '17 at 18:47
@PeterWood : Can we have multiple such variables in a single expression. – Ritesh Apr 25 '17 at 18:47
