listo

Listo is an enhanced version of the list type that aims to do the following:

• Make behavior more consistent. No more methods with "in-place" changes. Every method call returns a value
• Adds methods that are missing from the list type. For example, listo has a first method that returns self[0]
• A list of arguments passed in will be converted to a listo object, but a single argument that is an iterator will be unpacked into a listo object. This is useful for when you want to pass in a generator or other iterator into a function that expects a list

Usage

First install it via pip, poetry, or whatever you use

pip install listo

Then use it in your code

from listo import listo

lst = listo(1, 2, 3)
assert lst.first() == 1
assert lst.last() == 2

Usage: How listo handles initial arguments

For arguments passed in, it just converts them to a listo object

lst = listo(1, 2, 3)
assert lst == [1, 2, 3]

lst2 = listo([1, 2, 3]) # list is unpacked
assert lst2 == [1, 2, 3]

lst3 = listo((1, 2, 3)) # tuple is converted and unpacked
assert lst3 == [1, 2, 3]

lst4 = listo([1, 2, 3], (1, 2))  # Two args mean nothing is unpacked
assert lst4 == [[1, 2, 3], (1, 2)]

This is different from standard Python iterator behavior.
