For porting C extensions to Python 3. For general information about strings, see. This is always the dictionary of the current module inside a function or method, this is the module where it is defined, not the module from which it is called.

A class method receives the class as implicit first argument, just like an instance method receives the instance. Run the result of the translation under Python 3. Because we called the hello function within main and then only called main to run, the Hello, World! This is useful for accessing inherited methods that have been overridden in a class.

If it is a code object, it is simply executed. You can no longer write def foo a, b, c :. Python Module example def add a, b : return a + b To use this module, we use import keyword. The function assigns the value to the attribute, provided the object allows it. If it does not support either of those protocols, is raised. With mixed operand types, the coercion rules for binary arithmetic operators apply. The rest object is always a possibly empty list; the right-hand side may be any iterable.
