Python implements a command line that simulates a shell

Functional Requirements:

Simulating the shell's command-line interface with while loops and break implementations

The source code is as follows:

1 ImportOS2 3  whileTrue:##形成死循环 to form a shell environment4cmd = Raw_input ("[email protected] desktop]$")5     ifCmd:##判断是否有输入, there is true, there is no false6         ifcmd = ='Exit':7             Print 'Logout'8              Break9         Else:Ten os.system (cmd) One     Else: A         Continue  ##当输入为空时进入死循环

The effect is as follows:
