有人能解释一下如何使用python 3在两个函数之间传递变量吗

Question

我试图在两个函数之间传递一个变量，但我不明白哪里错了，因为它不起作用。这是我的python3脚本：

from tkinter import *
w1=Tk()
w2=Tk()
def go(which):
print(which)
b=Button(w2,text='print',command=lambda:go(which.get()))
b.pack()
w2.withdraw()
def main(which):
w2.deiconify()
b1=Button(w1,text='button 1',command=lambda:main('button 1'))
b1.pack()
b2=Button(w1,text='button 2',command=lambda:main('button 2'))
b2.pack()
w1.mainloop()

感谢

好吧，我刚刚自己解决了：

from tkinter import *
w1=Tk()
w2=Tk()
w2.withdraw()
def main(which):
w2.deiconify()
def go(which):
print(which)
b=Button(w2,text='print',command=lambda:go(which))
b.pack()
b1=Button(w1,text='button 1',command=lambda:main('button 1'))
b1.pack()
b2=Button(w1,text='button 2',command=lambda:main('button 2'))
b2.pack()
w1.mainloop()
