例如,名为A.B的模块表示了名为A的包中名为B的子模块。正如同用模块来保存不同的模块架构可以避免全局变量之间的相互冲突,使用圆点模块名保存像 NumPy 或 Python Imaging Library 之类的不同类库架构可以避免模块之间的命名冲突。 假设你现在想要设计一个模块集(一个“包”)来统一处理声音文件和声音数据。存在几种...
NumPy 的 masked_array 是处理缺失值的一种优雅方案。它通过在一个数据数组上添加一个布尔掩码数组,来标记哪些元素是缺失的。 掩码数组的基本概念:什么是掩码数组,为什么需要它。 创建掩码数组:如何创建和初始化 masked_array。 掩码数组的属性: understanding the attributes of a masked_array. Syntax error in tex...

your best choice depends on the extension modules you want to use and how you want to distribute your programs. CPython applications are often faster than Jython or IronPython, particularly if you use extension modules such as NumPy(covered in“Array Processing”); however, PyPy can often be ...
