python - 如何在 python 中定义全局列表并向其 append 本地列表

Question

我想定义一个全局列表并向其 append 一个列表。我通过一些点击事件获得了一个列表(i[0])并将其 append 到 mnum_list 中。现在我想创建一个全局列表并将 mnum_list append 到其中。知道如何做到这一点吗？

def OnClick(self, event):                                       
    name = event.GetEventObject().GetLabelText()
    cursor= self.conn.execute("SELECT * FROM ELEMENT where SYMBOL==?", (name,))
    elements = cursor.fetchall()
    print elements
    cursor= self.conn.execute("SELECT ATOMIC_NUMBER FROM ELEMENT where SYMBOL = ?", (name,))
    numbers = cursor.fetchone()[0]
    print numbers
    atomicnumber = numbers
    cursor= self.conn.execute("SELECT MOL_NUMBER FROM LINK where ELEMENT_NUMBER = ?", (atomicnumber,))
    mnumbers = cursor.fetchall()
    print mnumbers
    mnum_list = []
    for i in mnumbers:
         mnum_list.append(i[0])
    print mnum_list

如果没有赋值，则不需要 global 语句，只需:

def foo(x):
    sublist = range(x)
    glist.append(sublist)

如果延期:

def foo(x):
    sublist = range(x)
    glist.extend(sublist)
