pyarrow.compute.utf8_zero_fill

pyarrow.compute.utf8_zero_fill(strings, /, width, padding='0', *, options=None, memory_pool=None)

Left-pad strings to a given width, preserving leading sign characters.

For each string in strings, emit a string of length width by prepending the given padding character (defaults to ‘0’ if not specified). If the string starts with ‘+’ or ‘-’, the sign is preserved and padding occurs after the sign. Null values emit null.

Parameters:

stringsArray-like or scalar-like

Argument to compute function.

widthint

Desired string length.

paddingstr, default “0”

Padding character. Should be one Unicode codepoint.

optionspyarrow.compute.ZeroFillOptions, optional

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

If not passed, will allocate memory from the default memory pool.
