我有两个功能。请参见下面的功能；
def check_channel_number(self):
print "***************Channel Checker *********************"
print ''
user_channel_number = int(re.sub('\D', '', raw_input("Enter a channel number, (3digit): "))[:3]);
channel = ("channelNr= '%d'") % (user_channel_number)
print channel
# channel_search = channel + str(user_channel_number)
datafile = file('output.txt')
found = False
for line in datafile:
if channel in line:
found = True
print 'The channel number you entered is correct and will be deleted'
return user_channel_number
print 'The channel number you entered is not on the planner'
return False
只想在以下函数中使用（user_channel_number）的返回值。
def delete_events(self):
if user_channel_number == True:
return 'The program number is correct and will be deleted'
# action = 'DeleteEvent'
menu_action = 'all'
book = 'RECYC:687869882'
arg_list = [('C:\\Users\\yke01\\Documents\\StormTest\\Scripts\\Completed'
'\\Utils\\UPNP_Client_Cmd_Line.py')]
arg_list.append(' --action=')
arg_list.append(action)
arg_list.append(' --ip=')
arg_list.append('10.10.8.89')
arg_list.append(' --objectId=')
arg_list.append(book)
subprocess.call(["python", arg_list])
print 'The program deleted successfully'
当我运行脚本时，它说user_channel_number未全局定义？我如何user_channel_number在delete_events()函数内部调用？
函数不能共享其局部变量。您可以从第一个返回值，然后将其传递给第二个：
def check_channel_number(self):
...
return user_channel_number
def delete_events(self):
user_channel_number = self.check_channel_number()
...
或在对象上保存值：
def check_channel_number(self):
...
self.user_channel_number = user_channel_number
...
def delete_events(self):
if self.user_channel_number:
....
