听起来命令行界面就是您要询问的那部分。将用户输入映射到命令的一种好方法是使用字典，并且在python中，您可以通过在函数名称后加上（）来运行对函数的引用。这是一个简单的例子，向您展示我的意思
def firstThing(): # this could be your 'cd' task print 'ran first task'def secondThing(): # another task you would want to run print 'ran second task'def showCommands(): # a task to show available commands print functionDict.keys()# a dictionary mapping commands to functions (you could do the same with classes)functionDict = {'f1': firstThing, 'f2': secondThing, 'help': showCommands}# the actual function that gets the inputdef main(): cont = True while(cont): selection = raw_input('enter your selection ') if selection == 'q': # quick and dirty way to give the user a way out cont = False elif selection in functionDict.keys(): functionDict[selection]() else: print 'my friend, you do not know me. enter help to see VALID commands'if __name__ == '__main__': main()
