Idiomatic, simplified Python style

Write code that is idiomatic, simplified, and consistent with the rest of the codebase rather than clever or verbose. Concretely:

• Prefer built-in functions and idioms over manual reimplementations: use callable(obj) instead of hasattr(obj, '__call__'), isinstance(obj, str) instead of type(obj) is str, repr(obj) instead of calling obj.__repr__(), and os.path.join(...) instead of manual string concatenation for paths.
• Avoid unpythonic constructs such as map() with a lambda; use a list/dict comprehension instead, e.g. prefer [(category, x) for x in values] over map(lambda x: (category, x), values).
• Simplify boolean logic: return the expression directly instead of wrapping it in if/else (return all(...) rather than if all(...): return True else: return False), and avoid redundant comparisons like assert x == True or assert x == False—use assert x or assert not x instead.
• Don’t overcomplicate simple assignments with ternaries or conditional chains, e.g. use provide_automatic_options = "OPTIONS" not in methods rather than a verbose if/else or convoluted ternary when the logic is a single boolean expression.
• Use plain comments (#) rather than docstrings for inline/implementation notes; reserve docstrings for documenting the public interface.
• Avoid unnecessary escaping in string literals (prefer "<flask.g of 'flask_test'>" over an escaped-quote variant) and remove needless classes/instances when module-level functions or constants suffice.
• Maintain consistent formatting: use spaces (never tabs) for indentation, keep a blank line before new code blocks, and stick to the string-formatting style already used throughout the file/module (e.g. don’t mix %-formatting and .format() within the same area unless there’s a dedicated migration PR).

Following these guidelines keeps the codebase readable, consistent, and free of unnecessary complexity introduced by non-idiomatic or verbose constructs.
