Split: Split a field using a separator¶

class txf.Split(source, input, outputs, separator, defaults)¶

The Split transform replaces a field with a set of values generated from the inputs.

input: str¶: The name of the field to split. It will be dropped from the output, so use Copy if you need to preserve it.

outputs: tuple(str), str¶: The output field(s) receiving the split values. They cannot overwrite existing fields. Use Drop to remove unwanted fields.

separator: str or callable¶: Either a string or a callable used to split up the field. If it is a string, the value will be split using str.split. If it is a callable, it will be passed the value as a single argument and should return a list of values in the order of the outputs.

defaults: tuple¶: The value(s) to be used for missing elements of the separator result.

Usage¶

Split(p, 'Date', ('Month', 'Day', 'Year',), r'/')
Split(p, 'Year', ('Century' 'Decade', 'Year',), lambda y: [y // 100, (y % 100) // 10, y % 10])

Split(p, 'Query', ('Query', 'Mode',), '_', ('00', 'SERIAL',))
