NameError：全局名称“测试”未定义

Question

Hi I have two python files: project.py and test.py.

I am trying to import variable from test.py to project.py.

Following is the code:

test.py

newton = 0
def apple(n):
    global newton
    n = newton
    time.sleep(15)
    n = n + 1
    return

and in project.py

from test import *
class search(object):
      def __init__(self):
          self.servo = test.apple(n)
      def run(self):
          while (self.servo < 1):
                print "hELLO"

When I run project.py I get NameError: Global name 'test' is not defined in project.py self.servo = test.apple(n)

Can anyone point out what is wrong in my code?

Answer 1

What are you expecting test to be?

from test import *

This will load everything found in test, which in this case is test.py. So that will load the following into the global namespace:

• newton (with a value of 0 )
• apple (a function)

It does not load any symbol named test , so when you call test.apple in your __init__ method, you get a NameError .

If you want to import test.py as test , you instead need to just import the module itself, not import things from the module:

import test
