I'm trying to get Visual Studio Code to format (the colours not the layout) Python code with type annotations (hinting). It's failing to do so for the following code:
from typing import Iterator
# return math.factorial(x)
def fib(n: int) -> Iterator[int]:
a, b = 0, 1
while a < n:
yield a
a, b = b, a + b
"""
This function checks whether a string is a palindrome.
s - The string to check.
"""
def is_palindrome(s: str) -> bool:
return s == s[::-1]
"""
This function compares two strings of word letters and returns the percentage match.
p_string1 - The first letters to compare.
p_string2 - The second letters to compare.
"""
def compare_letters(p_string1: str, p_string2: str) -> float:
return 1.0
I'm using "python.formatting.provider": "black" but I also tried autopep8 and yapf. They all seem to fail in the same way, by getting it all mixed up after the type annotations.
When I go to the black website and paste the code into the Black Playground it works fine though.
I have upgraded using python -m pip install --upgrade black and it is showing the same version (black-19.10b0) as the Black Playground, so not sure where this is Visual Studio Code issue or a me issue.
I am using WinPython 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit (AMD64)] on win32.
Not really sure what to log a bug against with all this linting, formatting (colour/layout), Python parsing, etc.
Has anyone had any success with formatting Python type annotations in Visual Studio Code and what settings are you using?
