p328:设置搜索路径、site-specific 的 module 搜索路径 sys.path 即 sys.__dict__['path'] 是一个 PyListObject 对象,包含了一组PyStringObject 对象,每一个对象是一个module 的搜索路径。 第三方库路径的添加是 lib/site.py 完成的,在site.py 中完成两个动作: 1. 将 site-packages 路径加入到 sys.pat...
While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This means that functions can be passed around and used as arguments, just like any other object like str, int, float, list, and so on. Consider the...
一、对比总结 简单总结,通过 merge 和 join 合并的数据后数据的列变多,通过 concat 合并后的数据行列都可以变多(axis=1),而 combine_first 可以用一个数据填充另一个数据的缺失数据。 函数 说明 join 主要用于基于索引的横向合并拼接 merge 主要用于基于指

concat(list):将一个列表的frame行数加起来。 ix[index]:就是行索引,DataFrame的普通下标是列索引。 take(index):作用和ix差不多,都是查询行,但是ix传入行号,take传入行索引。 unstack():将行信息变成列信息。 apply(func,axis=0)和applymap(func):apply用在DataFrame会默认将func用在每个列上,如果axis=1表...
