Python sys 模块简介
sys 简介
“sys” 即 “system”，“系统”之意。该模块提供了一些接口，用于访问 Python 解释器自身使用和维护的变量，同时模块中还提供了一部分函数，可以与解释器进行比较深度的交互。
常用变量
sys.version
返回Python解析器版本号
import sys print(sys.version) #3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)]
sys.maxsize
操作系统所能承载的最大int值
print(sys.maxsize) #9223372036854775807
sys.maxunicode
最大的unicode值
print(sys.maxunicode) #1114111
sys.path
当前脚本的path环境变量
print(sys.path) #['E:\\worksp_py\\hardwary\\100day\\thirty', 'E:\\worksp_py\\hardwary', 'D:\\tool\\PyCharm 2020.2.2\\plugins\\python\\helpers\\pycharm_display', 'D:\\tool\\python3.8\\python38.zip', 'D:\\tool\\python3.8\\DLLs', 'D:\\tool\\python3.8\\lib', 'D:\\tool\\python3.8', 'E:\\worksp_py\\hardwary\\venvop', 'E:\\worksp_py\\hardwary\\venvop\\lib\\site-packages', 'D:\\tool\\PyCharm 2020.2.2\\plugins\\python\\helpers\\pycharm_matplotlib_backend']
sys.platform
返回操作系统平台名称
print(sys.platform) #win32
linux 返回 linux，Mac 返回 darwin
sys.args
运行脚本的名称以及所需的参数列表作为 list
import sys print(sys.argv)
sys.executable
Python 解析器的绝对路径
E:\worksp_py\hardwary\venvop\Scripts\python.exe
常用方法
sys.exit()
退出程序
print(sys.exit(0)) print(sys.exit(1))
sys.modules
返回系统导入的模块信息
print(sys.modules) #{'sys': <module 'sys' (built-in)>, 'builtins': <module 'builtins' (built-in)>, '_frozen_importlib': <module 'importlib._bootstrap' (frozen)>, '_imp': <module '_imp' (built-in)>,

IDLE 界面修改提示格式
每次打开 Python 的交互式界面，我们都会看到一个提示符>>>。不知道你有没有想过要把这个东西换成另外的什么呢？
就这俩货：sys.ps1和sys.ps2
所谓“ps”，应当是“prompts”的简写，即“提示符”。
这两个属性中，sys.ps1代表的是一级提示符，也就是进入 Python 交互界面之后就会出现的那一个>>>；而第二个sys.ps2则是二级提示符，是在同一级内容没有输入完，换行之后新行行首的提示符...。当然，两个属性都是字符串。
>>> import sys >>> sys.ps1 = '~' ~print('hahaha') hahaha ~
