Parser ：Parser目录中包含了Python解释器中的Scanner和Parser部分，即对Python源代码进行词法分析和语法分析的部分。除了这些，Parser目录下还包含了一些有用的工具，这些工具能够根据Python语言的语法自动生成Python语言的词法和语法分析器，与YACC非常类似。 Objects ：该目录中包含了所有Python的内建对象，包括整数，list，...

mv Parser/pgen Parser/pgen_for_build 清理编译好的项目文件,这一步是为了后面的交叉编译做准备 make distclean 整个步骤最重要的就是保存好python和pgen这两个可执行文件,因为之后在交叉编译Python时需要用到这两个文件。 给python源码打上交叉编译补丁
As you learned in the previous section, for Windows PowerShell, doing something like this doesn’t make a whole lot of sense because most of the time, these utilities are part of PowerShell itself. Because you aren’t dealing with separate executables, piping becomes less of a necessity. Ho...
