Python Application does nothing

This code stopped doing anything at all after I changed something that I no longer remember

#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.Co开发者_StackOverflow社区mputerName = 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()

edit: Lol sorry guys forgot to say its supposed to run the input


You should better describe your problem. Does it print the input prompt? Does it output anything? Does it exit or just sit there? I noticed a few issues while reading over this code that might help. You should be using raw_input(), not input(). Also, you don't actually do anything with userinput unless it == 'exit'. Which is won't, because you are just using input(), not raw_input(), so the person would have to enter 'exit' (including quotes) or else the loop will never exit. (Assuming it's not Python 3 Code)


It's doing nothing because there's no code to make it do anything. Try inserting a line like

print("You entered:", userinput)

at an appropriate place in your loop.


os.getenv() must have at least one param. Try os.getenv("HOST") or something.
