Every Python object has a little bit of memory overhead, and that overhead can really add up if you need to create a huge number of instances. Find out where this overhead comes from and some strategies for reducing memory usage.

In this step-by-step tutorial, you’ll learn how to inspect and manipulate IP addresses as Python objects with Python’s ipaddress module, improving your understanding of IP address mechanics and patterns used by the module.

Django is a “batteries included” framework, but one battery that isn’t included is two-factor authentication (2FA). Learn how to set up 2FA on the Django Admin site using an authentication app like Google Authenticator.

Arrange-Act-Assert is a test pattern that forces tests to focus on independent, individual behaviors. Learn how to use it for your tests!

The “Plus Minus Problem” asks whether or not it’s possible, given the numbers 1 to n, to add and subtract them in some manner so that the total sum is zero. The problem may not have many practical applications, but it’s a great way to illustrate how a little bit of reasoning can save you from exponential-time algorithms.

(是也乎:

涉及数论问题时, Python 反而是最趁手的工具, 毕竟形式上太直觉了.

HCrystalBall wraps time series forecasting projects like fbprophet, arima with autoarima, exponential smoothing from statsmodels, and (t)bats, and unifies them under a scikit-learn compatible interface so that you can leverage features like scikit-learn pipelines.

Thanks to high-quality pretrained models, Wikipedia, and Streamlit, deploying a state-of-the-art question answering system has never been easier!

gui->add_variable("string", strvar);

gui->add_group("Validating fields");
gui->add_variable("int", ivar);
gui->add_variable("float", fvar);
gui->add_variable("double", dvar);

gui->add_group("Complex types");
gui->add_variable("Enumeration", enumval, enabled)

gui->add_group("Other widgets");
gui->add_button("A button", [](){ std::cout << "Button pressed." << std::endl; });

screen->set_visible(true);
screen->perform_layout();
window->center();

看起来像是 C++ 代码.
