Similarly function arguments are first converted to the appropriate type specified by the function’s argument string or fails if this isn’t possible. There is however one quirk where the data type’s type hint (utf-8/non-printable raw data) is set based on whether a str or a bytes/byte...
A label associated with a variable, a class attribute or a function parameter or return value, used by convention as a type hint. Annotations of local variables cannot be accessed at runtime, but annotations of global variables, class attributes, and functions are stored in the __annotations_...

As a simple example, the following function definition contains a type hint to indicate that the input argument is type str, whereas the call to that function attempts to pass an integer:Python 複製 def commas_to_colons(input: str): items = input.split(',') items = [x...
