pyarrow.compute.starts_with#
- pyarrow.compute.starts_with(strings, /, pattern, *, ignore_case=False, options=None, memory_pool=None)#
Check if strings start with a literal pattern.
For each string in strings, emit true iff it starts with a given pattern. The pattern must be given in MatchSubstringOptions. If ignore_case is set, only simple case folding is performed.
Null inputs emit null.
- Parameters:
- stringsArray-like or scalar-like
Argument to compute function.
- pattern
str Substring pattern to look for inside input values.
- ignore_casebool, default
False Whether to perform a case-insensitive match.
- options
pyarrow.compute.MatchSubstringOptions, optional Alternative way of passing options.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
