daft.Expression.str.concat#

Expression.str.concat(other: str | daft.expressions.expressions.Expression) → Expression[source]#

Concatenates two string expressions together

Note

Another (easier!) way to invoke this functionality is using the Python + operator which is aliased to using str.concat. These are equivalent:

Example

>>> import daft
>>> df = daft.from_pydict({"x": ["foo", "bar", "baz"], "y": ["a", "b", "c"]})
>>> df.select(col("x").str.concat(col("y"))).collect()

│ barb │
├╌╌╌╌╌╌┤
│ bazc │
