(1)match()从string首字母开始匹配,string如果包含pattern子串,则匹配成功,返回Match对象,失败则返回None;一般用于:完全匹配,用于严格的校验 (2)search()若string中包含pattern子串,则返回Match对象,否则返回None,注意:如果string中存在多个pattern子串,只返回第一个;一般用于:是否包含,用户判断内容是否存在。 案例01: ...
Python自1.5版本起，通过re模块实现了Perl风格的正则表达式功能。compile函数：用于编译正则表达式，生成Pattern对象，以便后续进行匹配操作。match函数：尝试从字符串的起始位置匹配正则表达式。如果没有匹配成功，则返回None。成功匹配会返回一个Match对象，可通过group和groups函数获取匹配结果。search函数：扫描...

It spares you the need to find the package directory yourself and should be preferred whenever available. Functionally it's very similar to --include-data-dir but it has the benefit to locate the correct folder for you. With data files, you are largely on your own. Nuitka keeps track of...
