如何将此局部变量更改/设置为全局变量

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)

当我从函数中打印VarSC时，它给了我想要的值

VarSC = StringVar()

print(VarSC)

但是当我在函数外，在代码中打印它时，它会打印“PY\u VAR9”

Answer 1

您应该从函数返回VarSC的值并在外部打印它

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())
