मैं एक त्रुटि मिलती है:

NameError: global name 'bilbodogOther' is not not defined 

और त्रुटि यहीं चल रहा है:

def bilbodogscript(userid, choice, popupid): 
    if choice == 1: 
      bilbodogSelf.send(userid) 
    elif choice == 2: 
      bilbodogOther.send(userid) 

लेकिन मुझे समझ में नहीं आता, इसका क्या मतलब है?

Answer 1

जब आप ऐसा करेंगे:

Traceback (most recent call last): 
    File "D:\Documents and Settings\My Documents\StackOverflow\test.py", line 2, in <module> 
    print bilbodog 
NameError: global name 'bilbodog' is not defined 

इसके बजाय, जब आप अपने वेरिएबल ठीक से परिभाषित:

global bilbodog 
print bilbodog 

आपको यह त्रुटि है

global bilbodog 
bilbodog = 15 #Here you give a value to bilbodog (even None) 
print bilbodog 

यह काम करता है !!!

लेकिन अगर आप एक pythonic तरीके से करना चाहते हैं:

def definition(): 
    global bilbodog 
    bilbodog = 15 #Here you give a value to bilbodog (even None) 

def test(): 
    print bilbodog 

if __name__ == '__main__': 
    definition() 
    test() 

तो, मुझे लगता है कि आप निष्पादित करने के लिए bilbodogscript() जबकि bilbodog अभी तक परिभाषित नहीं है का प्रयास करते समय आप bilbodog.menuselect = bilbodogscript है। समस्या यह है कि इस लाइन के साथ आप पहली बार इस त्रुटि होना चाहिए:

Traceback (most recent call last): 
    File "D:\Documents and Settings\My Documents\StackOverflow\test.py", line 3, in <module> 
    bilbodog.menuselect = bilbodogscript 
NameError: name 'bilbodogscript' is not defined 

Answer 2

अजगर में, "वैश्विक" का अर्थ है "मॉड्यूल स्तर", और यह केवल उपयोग मॉड्यूल स्तर ऐसे नाम हैं जो पलटाव हो रहे हैं के लिए समारोह के भीतर है समारोह के भीतर। यह मॉड्यूल स्तर "आगे की घोषणा" के रूप में नहीं है - ऐसा कुछ जो अस्तित्व में नहीं है, क्योंकि जब कोई मॉड्यूल लोड होता है (निष्पादित या आयात किया जाता है), शीर्ष स्तर पर सभी कोड अनुक्रमिक रूप से निष्पादित होते हैं।

Answer 3

global variable 
variable = 100 #Any value required 

def function1(): 
    global variable 
    variable = new_value # manipulation 

def function2(): 
    print variable # accessed
