Python 应用程序不执行任何操作
在我更改了一些我不再记得
#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()
编辑的内容后，这段代码根本停止执行任何操作：哈哈，对不起，大家忘了说它应该运行输入
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.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()
edit: Lol sorry guys forgot to say its supposed to run the input

你应该更好地描述你的问题。是否打印输入提示？它输出什么吗？它会退出还是只是坐在那里？我在阅读这段代码时注意到一些可能有帮助的问题。您应该使用 raw_input()，而不是 input()。另外，除非用户输入==“退出”，否则您实际上不会对用户输入执行任何操作。这是不会的，因为您只是使用 input()，而不是 raw_input()，因此该人必须输入“exit”（包括引号），否则循环将永远不会退出。 （假设它不是Python 3代码）
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)
它什么也没做，因为没有代码让它做任何事情。 插入一行。
尝试在循环中的适当位置
It's doing nothing because there's no code to make it do anything. Try inserting a line like
at an appropriate place in your loop.
os.getenv()必须至少有一个参数。尝试 os.getenv("HOST") 或其他东西。os.getenv()must have at least one param. Tryos.getenv("HOST")or something.
