生成单个pyc文件
对于py文件,可以执行下面命令来生成pyc文件。
python -m foo.py
另外一种方式是通过代码来生成pyc文件。
import py_compile
py_compile.compile('/path/to/foo.py')
批量生成pyc文件
针对一个目录下所有的py文件进行编译。python提供了一个模块叫compileall,具体请看下面代码:
import compileall
compileall.compile_dir(r'/path')
这个函数的格式如下:
compile_dir(dir[, maxlevels[, ddir[, force[, rx[, quiet]]]]])
参数含义:
- maxlevels: 递归编译的层数
- ddir: If ddir is given, it is prepended to the path to each file being compiled for use in compilation time tracebacks, and is also compiled in to the byte-code file, where it will be used in tracebacks and other messages in cases where the source file does not exist at the time the byte-code file is executed. (谁能翻译一下( ⊙o⊙?)不懂)
- force: 如果True,不论是是否有pyc,都重新编译
- rx: 一个正则表达式,排除掉不想要的目录
- quiet:如果为True,则编译不会在标准输出中打印信息
命令行为:
python -m compileall <dir>
