About arithmetic and string¶
Operations are done with python operators and allows types that python allows, and return None if the operation can be done due to imcompatible types.
When operators are used, a jsonpath must be be fully defined otherwise if jsonpath-rw-ext can’t known if expression is a string or a jsonpath field, it will choice string.
Example with data:
{
'cow': 'foo',
'fish': 'bar'
}
cow + fish returns cowfish
$.cow + $.fish returns foobar
$.cow + “_” + $.fish returns foo_bar
$.cow + “_” + fish returns foo_fish
About arithmetic and list¶
Arithmetic can be used against two list if they have the same size.
Example with data:
{'objects': [
{'cow': 2, 'cat': 3},
{'cow': 4, 'cat': 6}
]}
$.objects[*].cow + $.objects[*].cat returns [6, 9]
