Python中如何将字符串转换为函数（方法）

使用eval返回值 简单案例代码如下：

def text():
    print("+++++++++++++++++++++++++++++++")

if __name__ == '__main__':

    name = "text"
    s = eval(name)
    s()

使用字符串转化为函数传递道类中使用代码如下：

def text():
    print("+++++++++++++++++++++++++++++++")

class Demo():
    def __init__(self,app):
        self.app = app
    def b(self):
        self.app()

if __name__ == '__main__':

    name = "text"
    s = eval(name)
    t = Demo(s)
    t.b()
