Note: When an exception is raised in Python, it is done with a traceback. The traceback gives you all the relevant information to be able to determine why the exception was raised and what caused it. Learning how to read a Python traceback and understanding what it is telling you is crucial to improving as a Python programmer.

SyntaxError: 'return' outside function. Return statements can only be included in a function. This is because return statements send values from a function to a main program. Without a function from which to send values, a return statement would have no clear purpose. Return statements come at the end of a block of code in a function.

Define an Exception Hierarchy for Your API. In the book Effective Python, Brett Slatkin suggests: "Define a Root Exception to Insulate Callers from APIs" (Item 87). Define a root exception for your API (This inherits from the built-in Exception class.) All exceptions raised by the API inherit from this root exception.

Raising Exceptions in Python. In Python programming, exceptions are raised when errors occur at runtime. We can also manually raise exceptions using the raise keyword. We can optionally pass values to the exception to clarify why.

In python, this error can come when the indentation or return function does not match. Example: def add (x, y): sum = x + y return (sum) print (" Total is: ", add (20, 50)) After writing the above code (syntaxerror return outside function python), Ones you will print then the error will appear as a " SyntaxError return outside function python ".

To resolve this error, return the value of the function to the caller or main program. ... Reason 3: Built-in Function Returns None. There is some function in Python that returns a None value, such as sort(), append(), etc. So, the "AttributeError" occurs when the "append()" function is called on the return value of these functions..
