Please let me know if there is a way I can pass boolean type as optional parameters in python. I know that one way is to process the string in if else condition and process it as below: def t_or_f(arg): ua = str(arg).upper() if 'TRUE'.startswith(ua): return True elif 'FALSE'.startswith(ua): return False

BetaThis happens because the type parameter simply passes the argument string to the function you provide—in this case, bool(). While this makes sense for int() or float(), bool() treats any non-empty string as True. Convert a string to a number (int, float) in Python; Notes on bool() Evaluation. bool() returns False for the following values:

BetaThe only Boolean operator with one argument is not. It takes one argument and returns the opposite result: False for True and True for False. Here it is in a truth table: A not A; ... If you expect a Python Boolean value but have a function that returns a Boolean value, then it will always be truthy. By default, user-defined types are always ...

BetaType predicate functions are user-defined functions that return whether their argument is an instance of a particular type. TypeGuard works similarly to TypeIs, but has subtly different effects on type checking behavior (see below). Using -> TypeGuard tells the static type checker that for a given function: The return value is a boolean.

BetaIn Python, virtually every value (with exception of NotImplemented) has a boolean value. It is a great feature, it is very convenient to write simple code. In builtin and extention functions, boolean arguments were historically parsed with the “i” format unit in PyArg_Parse*() functions. It accepts True and False, as well as integers 1 and 0, so it is compatible with very old Python code ...
