本次分享使用的是 32 位 mingw,32 位 python3.7。 1、错误和解决: 错误1:undefined reference to '_imp__Py_Initialize': 报错原因:没有使用 32 位的 python37.lib 或者是没有在编译的时候引用 python37.lib,如果当前的 mingw 是 32 位的,那么python就用 32 位的。
一、re.compile()简介 re模块中有re.match、re.serch、re.findall,也是最常用的,详细用法见链接 re.compile()是用来优化正则的,它将正则表达式转化为对象,re.search(pattern, string)的调用方式就转换为 pattern.search(string)的调用方式,多次调用一个正则表达式就重复利用这个正则对象,可以实现更有效率的...

The second is that we must use Cython to compile our source code into a native machine binary file. There are many ways to do this depending on your situation, but here we’re going to go with the simple option and use a command-line tool provided by Cython itself:...
