1、简介 地理编码 (Geocoding)是一个街道、地址或者其他位置(经度、纬度)转化为坐标的过程。反向地理编码 (Reverse geocoding)是将坐标转换为地址(经度、纬度)的过程。一组反向地理编码结果间可能会有所差异。例如:一个结果可能包含最临近建筑的完整街道地址,而另一个可能只包含城市名称和邮政编码。 2、百度 拾取坐标...

第36 行的charMapping变量中的字典将普通英语字符映射到黑客语字符。然而,由于可能有多个可能的黑客语字符(例如字母't'的'7'或'+'),charMapping字典中的每个值都是一个字符串列表。当创建新的黑客语字符串时,程序有 30%的机会简单地使用原始英文消息中的字符,有 70%的机会使用黑客语字符之一。这意味着同一个...

Keep in mind that fancy indexing, unlike slicing, always copies the data into a new array. Transposing Arrays and Swapping Axes Transposing is a special form of reshaping that similarly returns a view on the underlying data without copying anything. Arrays have the transpose method and also the...
