我有两个名为main.py和black.py的python模块：
Main.py内容如下：
import os,sys,string,time
import subprocess,commands,re
import random
import black
class bcolors:
BOLD = '\033[1m'
UNBOLD = '033[0m'
HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
def disable(self):
self.BOLD = ''
self.UNBOLD = ''
self.HEADER = ''
self.OKBLUE = ''
self.OKGREEN = ''
self.WARNING = ''
self.FAIL = ''
self.ENDC = ''
def print_menu():
#subprocess.call("tput clear")
print " "
#print bcolors.OKBLUE + (35 * '-') + bcolors.OKBLUE
print bcolors.OKBLUE + '\t\t\t\t' + (52 * '*') + bcolors.OKBLUE
print ("\t\t\t\t\t\tM A I N - M E N U")
print '\t\t\t\t' + (52 * '*')
print ("\t\t\t\t 0. Enter POD Name(s).")
print ("\t\t\t\t 1. QUIT")
print '\t\t\t\t' + (52 * '*') + bcolors.ENDC
is_valid=0
while not is_valid:
try :
choice = int ( raw_input('Enter your choice [0-24] : ') )
is_valid = 1
except ValueError, e :
print ("'%s' is not a valid integer." % e.args[0].split(": ")[1])
return choice

if rUser != "oracle":
print bcolors.FAIL + " Login as mc_admin to run the script. Exiting .." + bcolors.ENDC
exit ()
else:
os.system("tput clear")
choice = print_menu()

global podList #

while choice >= 0 and choice < 1:
if choice == 0:
pPODName()
black.blackout()
和black.py内容如下：
def blackout():
def pPODName():
global podList
podList = str(raw_input('Enter pipe separated list of PODS : ')).upper().strip()
if podList:
try:

uResp = str(raw_input('Do You Want To Continue [YES|Y|NO|N] : ')).upper().strip()
#if uResp == "NO" or uResp == "N":
if uResp != "YES" and uResp != 'Y':
pPODName ()
if __name__ == '__main__':
blackout()
我想在main.py中调用black.py模块但是当我运行main.py时出现以下错误：
[oracle@localhost tmp]$ ./main.py
****************************************************
M A I N - M E N U
****************************************************
0. Enter POD Name(s).
1. QUIT
Enter your choice [0-24] : 0
Traceback (most recent call last):
File "./main.py", line 131, in <module>
pPODName()
NameError: name 'pPODName' is not defined
答案 0 :(得分：2)
pPODName尚未定义。
pPODName在另一个函数中定义，因此只有该函数才能识别它。这被称为在本地范围内。基本上，函数中定义的任何内容只能由该函数访问，而不能用于任何其他函数。
举个例子：
def test():
def test_local():
return 3
return test_local()
运行功能测试为您提供
>>> test()
3
然而运行函数test_local
>>> test_local()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'test_local' is not defined
其次，在导入模块时，您需要使用模块名称对其进行限定，就像您使用black.blackout()一样，需要使用：
from black import *
虽然我个人不喜欢这样，但很难看出方法的来源。
要让main.py能够调用pPODName，必须在整个模块中定义它，例如：
def blackout()
#do stuff here
def pPODNAME()
#do other stuff here
#note the indentation level is the same as blackout
你必须用
来调用它black.pPODName()
来自main.py
答案 1 :(得分：0)
您有一些编程层次结构错误 为什么pPODName是停电的内在功能？ 詹姆斯说 - 如果你使用外部和内部功能，外部需要调用内部。
我建议你在black.py中使用常规功能 blackout函数除了包含pPODName之外什么都不做，所以你不需要它
