NameError: name 'exit' is not defined
提问by Tim
I used cxfreeze to create a Windows executable from planrequest.py. It seemed to work ok, but when I run the exe file I get NameError: name 'exit' is not defined
我使用 cxfreeze 从 planrequest.py 创建了一个 Windows 可执行文件。它似乎工作正常，但是当我运行 exe 文件时，我得到NameError: name 'exit' is not defined
name exit is not defined in pythonstates that the fix is to use import sys. However, I use import sys. The code runs fine as a python script (as in, I extensively tested the command line arguments before compiling to an executable.)
名称退出未在 python状态中定义，修复是使用import sys. 但是，我使用 import sys. 该代码作为 python 脚本运行良好（例如，在编译为可执行文件之前，我广泛测试了命令行参数。）
import socket
import sys
if len(sys.argv) == 1:
print("Usage:")
print("PlanRequest [Request String] [Server IP (optional: assumes 127.0.0.1 if omitted)]")
exit()
#[do stuff with the request]

Importing sys will not be enough to make exitlive in the global scope.
导入 sys 不足以exit在全局范围内生效。
You either need to do
你要么需要做
from sys import exit
exit()
or
或者
import sys
sys.exit()
Note that, as you are also using argv, in the first case you should dofrom sys import argv,exit
请注意，由于您也在使用 argv，因此在第一种情况下您应该这样做from sys import argv,exit
回答by Damián Rafael Lattenero
You have to apply the function to sys:
您必须将该函数应用于 sys：
from sys import exit
exit()
because exitis the function itself, you need to call it with ()
因为exit是函数本身，你需要调用它()
