Python应用程序什么也不做

Question

我再也不记得我做过什么了

#Dash Shell
import os
import datetime

class LocalComputer:
    pass

def InitInformation():
    Home = LocalComputer()
    #Acquires user information
    if (os.name == "nt"):
        Home.ComputerName = os.getenv("COMPUTERNAME")
        Home.Username = os.getenv("USERNAME")
        Home.Homedir = os.getenv("HOMEPATH")
    else:
        Home.ComputerName = os.getenv()
        Home.Username = os.getenv("USER")
        Home.Homedir = os.getenv("HOME")
    return Home

def MainShellLoop():
    print ("--- Dash Shell ---")
    Home = InitInformation()
    userinput = None
    currentdir = Home.Homedir
    while (userinput != "exit"):
        rightnow = datetime.datetime.now()
        try:
            userinput = input(str(Home.ComputerName) + "\\" + str(Home.Username) + ":" + str(rightnow.month) + "/" + str(rightnow.day) + "/" + str(rightnow.year) + "@" + str(currentdir))
        except:
            print("Invalid Command specified, please try again")

MainShellLoop()

编辑：抱歉，伙计们忘了说它应该运行输入

Answer 1

它什么也不做，因为没有代码可以让它做任何事情。试着插入一行

print("You entered:", userinput)

在一个适当的地方。在
