函数调用问题

wuyoujiao

各位大神，我在程序中定义了七个函数，想实现用随机函数来随机调用其中任意一个函数，如何实现？我采用的办法是把函数名保存在列表中，利用随机索引来调用函数，但是不行。

形参都一致吗 返回类型也是一致的吗

1. def fun1():
   
2.     pass
   
3. 
   
4. def fun2():
   
5.     pass
   
6. 
   
7. def fun3():
   
8.     pass
   
9. 
   
10. lst = [fun1, fun2, fun3]
    
11. import random
    
12. random.choice(lst)()

list=['image_I','image_L','image_J','image_O','image_S','image_T','image_Z']
list[random.randint(0,6)]+'()'
这种方式也是可以的啦？

看了各位的回复，查找了资料，才知道还有evel和exec 这样的好东西。谢谢

阿巴阿巴，其实我觉得设置一个随机数然后不同数字为条件设分支语句也可以？我真的是大新手
