python中设计一个在全局作用域、嵌套作用域、局部作用域存在部分相同变量名的函数；在最内部函数(myfun3)中，打印myfun3中的变量值；并修改对myfun3函数而言的嵌套作用域和全局作用域中同名变量的值，并在相应的作用域中打印出修改后的变量的值。

此问题属于技术问题，我可以回答。以下是实现代码：

var_global = "I am in the global scope"

def myfun1():
    var_nonlocal = "I am in the nested scope"
    print(var_global, var_nonlocal)  # prints "I am in the global scope I am in the nested scope"
    
    def myfun2():
        var_local = "I am in the local scope"
        print(var_global, var_nonlocal, var_local)  # prints "I am in the global scope I am in the nested scope I am in the local scope"
        
        def myfun3():
            var_local = "I am in the inner local scope"
            nonlocal var_nonlocal
            global var_global
            var_nonlocal = "I am modified in inner function"
            var_global = "I am modified in inner function too"
            print(var_local)
            print(var_nonlocal)
            print(var_global)
            
        myfun3()
    myfun2()
    
myfun1()

输出结果：

I am in the global scope I am in the nested scope
I am in the global scope I am in the nested scope I am in the local scope
I am in the inner local scope
I am modified in inner function
I am modified in inner function too
