pyarrow.compute.ascii_ltrim(strings, *, memory_pool=None, options=None, characters)

Trim leading characters present in the characters arguments.

For each string in strings, emit a string with leading characters removed that are present in the characters argument. Null values emit null. Both the input string as the characters argument are interepreted as ASCII characters, to trim non-ASCII characters, use utf8_trim.

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

  • options (pyarrow.compute.TrimOptions, optional) – Parameters altering compute function semantics.

  • characters (optional) – Parameter for TrimOptions constructor. Either options or characters can be passed, but not both at the same time.
