Answer

The statement "Every syntax error is an exception but every exception cannot be a syntax together" is justified as follows:

  1. Syntax errors are exceptions: In Python, syntax errors occur when the code does not conform to the syntax rules of the language. For instance, forgetting a parenthesis or mismatching indentation can trigger a SyntaxError. These are subclassed under exceptions, and the Python interpreter flags these errors before the code is executed. Therefore, every syntax error is indeed an exception, specifically a subclass of an exception that deals with syntactical faults in code.

  2. Not all exceptions are syntax errors: Exceptions in Python handle a broader range of issues beyond just syntax-related errors. Exceptions can occur during the execution of a program at runtime, handling issues such as operations that the code is unable to perform (like division by zero), or environmental issues (like reading a non-existent file). These are known as runtime exceptions and include ZeroDivisionError, FileNotFoundError, etc., which are not related to syntax but to the logic, state of resources, or conditions during the execution of the program.

Thus, while syntax errors strictly relate to incorrect Python syntax preventing the code from running, exceptions can be raised due to various errors that might occur during runtime as well as compile time (syntax error being one such compile-time exception). This distinction supports the given statement effectively.
