pyarrow.compute.ascii_upper

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

Transform ASCII input to uppercase.

For each string in strings, return an uppercase version.

This function assumes the input is fully ASCII. It it may contain non-ASCII characters, use “utf8_upper” 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.
