python pyc

Python的pyc文件是Python源代码编译后生成的字节码文件，用于提高程序的执行速度。当Python解释器执行py文件时，如果存在对应的pyc文件，解释器会加载pyc文件而不是重新编译源代码。引用中提到，Python在加载pyc文件时会检查magic number，如果不一致则会拒绝加载。可以使用py_compile模块来手动将py文件编译为pyc文件，如引用所示。在运行过程中，如果遇到import语句，Python会在设定好的路径中查找对应的pyc文件或pyd文件，如果找不到，会先将对应的py文件编译为PyCodeObject，然后写入到pyc文件中，如引用所述。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
