bitarray: efficient arrays of booleans This library provides an object type which efficiently represents an array of booleans. Bitarrays are sequence types and behave very much like usual lists. Eight bits are represented by one byte in a contiguous block of memory. The user can select between...
Booleans PythonBooleans ❮ PreviousNext ❯ Booleans represent one of two values:TrueorFalse. Boolean Values In programming you often need to know if an expression isTrueorFalse. You can evaluate any expression in Python, and get one of two answers,TrueorFalse....

Alternately array of quantiles, e.g. [0, .25, .5, .75, 1.] for quartiles. labels : array or False, default None Used as labels for the resulting bins. Must be of the same length as the resulting bins. If False, return only integer indicators of the bins. If True, raises an ...

为了跟踪我们的渲染器模块,我们将创建一个名为renderers的子包,并将所有渲染器模块放在这个子包中。让我们现在创建这个子包。在主charter目录中创建一个名为renderers的新目录,并在其中创建一个名为__init__.py的新文件,作为包初始化文件。这个文件可以为空,因为我们不需要做任何特殊的初始化来初始化这个子包。
