pyarrow.compute.ascii_lower

pyarrow.compute.ascii_lower(strings, *, memory_pool=None)

Transform ASCII input to lowercase.

For each string in strings, return a lowercase version.

This function assumes the input is fully ASCII. It it may contain non-ASCII characters, use “utf8_lower” instead.

Parameters

• strings (Array-like or scalar-like) – Argument to compute function

• memory_pool (pyarrow.MemoryPool, optional) – If not passed, will allocate memory from the default memory pool.
