How the Python program opens and runs

Python programs can be run in roughly two ways, one is directly interpreted by the Python interpreter, and the other is to first compile the Python program into a binary file before running.

Source code-python source code file with "py" as the extension, interpreted by the Python program, do not need to compile;. Byte code-python The source file is compiled with a file with an extension of "PYC";-Compile Method-    import py_compile                     py_compile.compile ("hello.py"). Optimized code-optimized source files , the extension ". Pyo"-python-o-m py_compile hello.py above three kinds can be directly run
