pyarrow.compute.ascii_lpad(strings, *, memory_pool=None, options=None, width, padding=' ')¶ For each string in strings, emit a right-aligned string by prepending the given UTF8 codeunit. Null values emit null..
For each string in strings, emit a right-aligned string by prepending the given ASCII character. Null values emit null.
- 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.
options (pyarrow.compute.PadOptions, optional) – Parameters altering compute function semantics.
width (optional) – Parameter for PadOptions constructor. Either options or width can be passed, but not both at the same time.
padding (optional) – Parameter for PadOptions constructor. Either options or padding can be passed, but not both at the same time.
