In this post, we will be talking about how Python likes to deal with "list-like objects". We will be diving into some quirks of Python that might seem a bit weird and, in the end, we will hopefully teach you how to build something that could actually be

Although the previous code might already seem like it was a Python package because it contained multiple files, a Python package also needs an__init__.pyfile. In this section, you'll learn how to create this__init__.pyfile and then pip install the package into your local Python ...
If the boolean expression evaluates to TRUE, then the block of statement(s) inside the if statement is executed. In Python, statements in a block are uniformly indented after the : symbol. If boolean expression evaluates to FALSE, then the first set of code after the end of block is execu...
# Move the camera to a position high above the screen# --that is, offset it along the z-axis.self.camera.setPos(0,0,32)# Tilt the camera down by setting its pitch.self.camera.setP(-90) 不过场景看起来还是没有立体感,我们会在下一篇中进行改进。

At the core of many data-driven personalized decision scenarios is the estimation of heterogeneous treatment effects: what is the causal effect of an intervention on an outcome of interest for a sample with a particular set of features? In a nutshell, this toolkit is designed to measure the ...

In SQL terms, a QuerySet equates to a SELECT statement, and a filter is a limiting clause such as WHERE or LIMIT. You get a QuerySet by using your model’s Manager. Each model has at least one Manager, and it’s called objects by default. Access it directly via the model class, ...
