The second part is the context. In the example above, it was the expressionfor i in range(10). The context consists of an arbitrary number offorandifclauses. The single goal of the context is to define (or restrict) the sequence of elements on which we want to apply the expression. ...
Bounded loops are achieved through the use ofFOR-NEXTstatements. The loop is controlled by a numeric loop variable that is incremented or decremented from a start value to an end value. The loop terminates when the loop variable reaches the end value. The loop variable must also be specified ...
When it comes to pure replacements, those are the most common methods you will come across when you want to replace elements in a list in Python. There are also things likePython List Comprehensions, but that kind of defeats the purpose of replacing items. Another way to work with lists in...
This would normally be abysmally slow in Python. However, numpy is used to evaluate the SDF on entire batches of points simultaneously. Furthermore, multiple threads are used to process batches in parallel. The result is surprisingly fast (for marching cubes). Meshes of adequate detail can still...

In programming, a star pattern refers to a design or shape created by using asterisk (*) characters. Star patterns are a common exercise for beginners to practice control structures like loops and conditional statements like if-else in Python. A star pattern typically consists of rows and column...

Before getting the window on the screen, there are a few key concepts to introduce about how applications are organized in the Qt world. If you're already familiar with event loops you can safely skip to the next section. The core of every Qt Applications is the QApplication class. Every...
