smallparts.sequences
Functions for sequences.
Source: smallparts/sequences.py
Module contents
This module defines the constant
smallparts.sequences.DEFAULT_SEPARATOR
simply
','(an ASCII comma)
and the following functions:
smallparts.sequences.flatten(iterable, depth=None)
Returns a list containing all items in iterable which are either strings bytes or non-iterable objects. This function uses recursion, thus expanding all iterables except strings or bytes. You can limit recursion to depth levels by providing depth as a positive number.
smallparts.sequences.raw_join(iterable, prefix=None, separator=DEFAULT_SEPARATOR, final_separator=None, suffix=None):
Returns a unicode string containing the list items joined together according to the provided parameters.
separator is the string separating all items except the next-to-last and last ones in the returned string, final_separator is the string separating the next-to-last and last items, and defaults to the value of separator.
prefix and suffix default to empty strings.
Usage examples
>>> from smallparts import sequences
>>> nested_list = [1, [2, [3, [4, [5, 6], 7], 8], 9], 10]
>>> sequences.flatten(nested_list)
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> sequences.flatten(nested_list, depth=1)
[1, 2, [3, [4, [5, 6], 7], 8], 9, 10]
>>> sequences.flatten(nested_list, depth=2)
[1, 2, 3, [4, [5, 6], 7], 8, 9, 10]
>>>
>>> sequences.raw_join(['a', 'b', 'c', 'd'])
'a,b,c,d'
>>> sequences.raw_join(['a', 'b', 'c', 'd'], separator=', ', final_separator=' and ')
'a, b, c and d'
>>> sequences.raw_join(['a', 'b', 'c', 'd'], separator='|', prefix='(', suffix=')')
'(a|b|c|d)'
>>>
