Usage

• NamedTuple

"""This class imitates the behavior of the `named tuple`."""

from xloft import NamedTuple


nt = NamedTuple(x=10, y="Hello", _id="507c7f79bcf86cd7994f6c0e")
# or
d = {"x": 10, "y": "Hello", "_id": "507c7f79bcf86cd7994f6c0e"}
nt = NamedTuple(**d)

• Converters

"""Convert the number of bytes into a human-readable format."""

from xloft import to_human_size, int_to_roman, roman_to_int
# from xloft.converters import to_human_size, int_to_roman, roman_to_int

roman_to_int("MCMXCIV")  # => 1994
