sys模塊：system指的是解釋器（os指的是操作系統）

常用操作：用于接收系統操作系統調用解釋器傳入的參數
實驗操作：
在python工具中敲入以下代碼：
import sys
print(sys.argv)
#獲取腳本名稱 sys.argv[0]
print(sys.argv[0])
#獲取腳步傳遞的第一個參數：
print(sys.argv[1])
#獲取腳本傳遞的第二個參數
print(sys.argv[2])
在命令行中運行：
運行成功

import os import sysprint(sys.version)# 作用：根據python版本編寫符合不同版本的程序 使程序可兼容 if sys.version[0] == '2':print('running in python2...') elif sys.version[0] == '3':print('running in python3...')# 返回模塊的搜索路徑，初始化使用PYTHONPATH環境變量 print(sys.path) # 可以實現跨平臺 print(sys.platform) if sys.platform == 'linux':os.system('ifconfig') else:os.system('ipconfig')3.6.4 (default, Aug 10 2018, 11:14:49) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] running in python3...
