在开始之前,我们先限定下python解释器的意思。当讨论Python的时候,解释器这个词可以用在不同的地方。有的时候,解释器指的是Python Interpreter,也就是你在命令行交互界面上输入python的时候。有的时候人们或多或少的交换使用python和python解释器来表明python从执行到结束的的过程。在本章中,解释器有更加确切的意思:python...

注释(Comments)是用来向开发者(用户)提示或解释某些代码的思路、作用和功能等,可以添加到代码中的任何位置。Python 解释器(Python Interpreter)在执行程序(代码)时会忽略注释部分,不做任何处理,即注释部分不会被 Python 解释器执行。 在代码中添加适当的注释量很重要,注释通常占源代码的 1/3 左右。
You can run this program in the command line using: ./FMReceiver.py arguments. Consequently, the Python interpreter is invoked and the code in this script executed line by line orderly. Python is an interpreted language, similar to MATLAB. As a result, no compilation and linking is necessary...
