Return value of random_letters is not always a list

[svisser]

• Faker version: 8.10.1
• OS: Ubuntu 20.04

The return type of random_letters is not always a list as indicated in the docstring:

faker/faker/providers/__init__.py

Lines 194 to 195 in 2dac486

	def random_letters(self, length=16):
	"""Generate a list of random ASCII letters (a-z and A-Z) of the specified ``length``.

Steps to reproduce

>>> from faker import Faker
>>> f = Faker()
>>> f.random_letters(length=0)
[]
>>> f.random_letters(length=1)
('Y',)
>>> f.random_letters(length=2)
['o', 'K']
>>> f.random_letters(length=3)
['L', 'k', 'M']

Expected behavior

type(f.random_letters(length=n)) should be list when n=1

Actual behavior

type(f.random_letters(length=n)) has type tuple when n=1
