但可以对一个tuple重新赋值,tuple的存在可能基于两个原因:1)在python中,它比list操作速度更快,如果我们定义一个常量集,不需要修改,只需要遍历,则最好用tuple;2)安全性:由于tuple不能进行修改,那么对于这种类型的数据,tuple可以避免数据被偶然修改。
1.1. Python scientific computing ecosystem python的科学计算生态系统 python与Matlab或R不同,Python不提供预先捆绑的科学计算模块集。以下是可以结合使用以获得科学计算环境的基本构建块: Python,一种通用的现代计算语言 语言:流控制,数据类型(string,int),数据集合(列表,字典)等 标准库的模块:字符串处理,文件管理,简...

This framework is largely taken from mapand reducefunctions commonly used in functional programming,[2]although the actual semantics of the framework are not the same.[3]MapReduce implementations have been written in C++, Java, Pythonand other languages.[edit] Logical viewThe Mapand Reducefunc...
Throughout the book, you'll work with examples from the wider scientific Python ecosystem, using code that illustrates principles outlined in the book. Using actual scientific data, you’ll work on real-world problems with SciPy, NumPy, Pandas, scikit-im
