Python prime number generator. It is a valid identifier just like _foo, foo_ or _f_o_o_.

Python prime number generator In Python this is simply =. Python gotcha: depending on the Python version you are using, % is also the (deprecated) string interpolation operator, so watch out if you are coming from a language with automatic type casting (like PHP or JS) where an expression like '12' % 2 + 3 is legal: in Python it will result in TypeError: not all arguments converted during string Sep 28, 2009 · Python is not C or C++. source Otherwise, any special meaning of _ is purely by Jan 17, 2013 · In Python 3. An @ symbol at the beginning of a line is used for class and function decorators: PEP 318: Decorators Python Decorators - Python Wiki The most common Python decorators are: @property @classmethod @staticmethod An @ in the middle of a line is probably matrix multiplication: @ as a binary operator. 10: In a case pattern within a match statement, _ is a soft keyword that denotes a wildcard. What does asterisk * mean in Python?

The only exception are match statements since Python 3. It also seems like this will be enforced in future versions as described in What about existing uses of annotations: Side note, seeing as Python defines this as an xor operation and the method name has "xor" in it, I would consider it a poor design choice to make that method do something not related to xor like exponentiation. To translate this pseudocode into Python you would need to know the data structures being referenced, and a bit more of the algorithm implementation. See reference below. Different design decisions went into making the language. I think it's a good illustrative example of how it simply calls the __xor__ method, but to do that for real would be bad practice. Some notes about psuedocode: := is the assignment operator or = in Python = is the equality operator or == in Python There are certain styles, and your mileage may vary: Python slicing is a computationally fast way to methodically access parts of your data. It is a valid identifier just like _foo, foo_ or _f_o_o_. In particular, Python deliberately does not define assignment operators that can be used in an arbitrary expression; rather, there are assignment statements and augmented assignment statements. . In my opinion, to be even an intermediate Python programmer, it's one aspect of the language that it is necessary to be familiar with. Aug 31, 2008 · See What do ** (double star/asterisk) and * (star/asterisk) mean in a function call? for the complementary question about arguments.
