flati
Flatten nested iterable object (Pure-Python implementation)
Japanese document is available: https://qiita.com/yukinoi/items/9570c76034c28bdae0a8
Installation
$ pip install flati
Usage
import flati
iterable = [(1, 2, 3), (4, (5, 6))]
list(flati.flatten(iterable))
# => [1, 2, 3, 4, 5, 6]
# The flati.flatten function returns a generator
import types
isinstance(flati.flatten(iterable), types.GeneratorType)
# => True
# If you want to avoid flattening specific type, then use "ignore" parameter
iterable = [('abc'), ('def', ('g', 'hi'))]
list(flati.flatten(iterable, ignore=str))
# => ['abc', 'def', 'g', 'hi']
# The flatten_non_str function is alias of "flatten(iterable, ignore=str)"
iterable = [('abc'), ('def', ('g', 'hi'))]
list(flati.flatten_non_str(iterable))
# => ['abc', 'def', 'g', 'hi']Tips
If you want to flatten numpy.ndarray, I recommend using following methods:
numpy.ravel()
ndarray.reshape(-1)
ndarray.flatten() # This method is a bit slow because it makes a copy
