Operators

The same 3 types that share the indexing operator (str, bytes, and arrays) also share the ability to concatenate two values. The ++ operator is used for that purpose:

Input

Run

select 'Hello' ++ ' world';

select 'Hello' ++ ' world';

Output Objects

Press the 'Run' button to evaluate the input

Input

Run

select b'byte' ++ b'-string';

select b'byte' ++ b'-string';

Output Objects

Press the 'Run' button to evaluate the input

Input

Run

select [1, 1] ++ [2, 3];

select [1, 1] ++ [2, 3];

Output Objects

Press the 'Run' button to evaluate the input

Note that the concatenation operator does not work for tuples, which are free-standing heterogenous objects. Items inside a tuple can be concatenated normally, however:

Input

Run

with t1 := ('Hel', 'lo '),
     t2 := ('wor', 'ld!'),
# Doesn't work
# select t1 ++ t2 

# Works
select t1.0 ++ t1.1 ++ t2.0 ++ t2.1;

with t1 := ('Hel', 'lo '),
     t2 := ('wor', 'ld!'),
# Doesn't work
# select t1 ++ t2 

# Works
select t1.0 ++ t1.1 ++ t2.0 ++ t2.1;

Output Objects

Press the 'Run' button to evaluate the input
