NoReturn type incorrectly used in some functions.

[stitova-idm]

This doesn't cause an issue during run-time, but if you call these functions in your code, the code after them is highlighted as UNREACHEABLE in PyCharm.

NoReturn explanation:

Functions that raise exceptions and never return:

from typing import NoReturn

def fatal_error(message: str) -> NoReturn:
    """This function never returns; it always raises an exception."""
    raise RuntimeError(message)

fatal_error("Something went wrong!")  # 🚨 Raises RuntimeError

Here, fatal_error() always raises an exception and does not return any value.
Infinite loops (never terminating functions):

from typing import NoReturn

def infinite_loop() -> NoReturn:
    """This function never returns because it runs forever."""
    while True:
        print("Running forever...")

infinite_loop()  # 🔄 Runs indefinitely

Since the function runs indefinitely, it never reaches a return statement.
What NoReturn Does Not Mean
It does not mean the function returns None.
If a function returns nothing, it should be annotated as -> None instead.

def do_nothing() -> None:
    pass  # ✅ This function returns None, so NoReturn is NOT correct.
