如何更改/設置這個局部變量變成一個全球性

Question

def SelectedCarFunction(event=None): 
    a = Var2.get() 
    b = Var3.get() 
    c = Var4.get() 
    if Model == "a" and Colour == "b" and Wheels == "c": 
     VarSC = (Three_Series[0]) 
     print(VarSC) 

當我從功能打印VarSC它給了我的價值我想

VarSC = StringVar() 

print(VarSC) 

但是，當我打印功能外，內我的代碼，它打印「PY_VAR9」

Answer 1

您應該從函數中返回VarSC的值並將其打印到外部。

def SelectedCarFunction(event=None): 
    a = Var2.get() 
    b = Var3.get() 
    c = Var4.get() 
    if Model == "a" and Colour == "b" and Wheels == "c": 
     VarSC = (Three_Series[0]) 
     return VarSC 

print(SelectedCarFunction())
