Multiple Assignment
Multiple values can be assigned to multiple variables all at once.
x,y=1 2 3, 2:5;
x;
// output
[1,2,3]
y;
// output
2 : 5
x,y=(1 2 3, 2:5);
x;
// output
[1,2,3]
y;
// output
2 : 5
// multiple assignments by functions returning more than one value
def foo(a,b): [a+b, a-b]
x,y = foo(15,10);
x;
// output
25
y;
// output
5
// multiple assignments from the same value
x,y=10;
x;
// output
10
y;
// output
10
// Multiple assignments using columns from a matrix. The variables will take columns from the matrix sequentially. The number of variables must be the same as the number of columns in the matrix.
x,y = 1..10$5:2;
x;
// output
[1,2,3,4,5]
y;
// output
[6,7,8,9,10]
// Multiple assignments using rows from a table. The variables will take rows from the table sequentially. The number of variables must be the same as the number of rows in the table.
t = table(1 2 3 as id, 4 5 6 as value, `IBM`MSFT`GOOG as name);
t;
id | value | name |
---|---|---|
1 | 4 | IBM |
2 | 5 | MSFT |
3 | 6 | GOOG |
a,b,c = t;
a;
// output
name->IBM
value->4
id->1
b;
// output
name->MSFT
value->5
id->2
c;
// output
name->GOOG
value->6
id->3
