pyarrow.compute.replace_substring_regex(strings, /, pattern, replacement, *, max_replacements=None, options=None, memory_pool=None)

Replace matching non-overlapping substrings with replacement.

For each string in strings, replace non-overlapping substrings that match the given regular expression pattern with the given replacement. If max_replacements is given and not equal to -1, it limits the maximum amount replacements per input, counted from the left. Null values emit null.
