Python NameError: nome globale "NAME" non è definito! (Ma è definito)

Question

Questo è il mio codice Python:

import es, popuplib, cmdlib

def unload(): 
    cmdlib.unregisterSayCommand('!wpa') 

ottengo un errore:

NameError: global name 'bilbodogOther' is not not defined 

e l'errore sta succedendo proprio qui:

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

Ma Non lo capisco, cosa significa?

Answer 1

Quando si esegue:

global bilbodog 
print bilbodog 

avete questo errore:

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 

Invece quando si definiscono le variabili correttamente:

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

E funziona !!!

Ma se si vuole fare in modo divinatorio:

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

def test(): 
    print bilbodog 

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

Così, quando fate bilbodog.menuselect = bilbodogscript penso che si tenta di eseguire bilbodogscript() mentre bilbodog non è ancora definita. Il problema è che con questa linea si dovrebbe prima avere questo errore:

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

In Python, "globale" significa "livello di modulo", ed è solo l'uso è a funzione per i nomi di livello di modulo che devono essere rimbalzo all'interno della funzione. Non è inteso come una "dichiarazione diretta" a livello di modulo - qualcosa che non esiste, poiché quando un modulo viene caricato (eseguito o importato), tutto il codice al livello superiore viene eseguito in sequenza.

Answer 3

global variable 
variable = 100 #Any value required 

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

def function2(): 
    print variable # accessed
