Answer 1

使用import random代替from random import random

Answer 2

In addition to @zero323's answer, if you don't need more than choice function, you can do this instead:

from random import choice

And use it straight away:

a = choice(list)

Also your program might not do what you wanted. Currently, if you find 5 in your list, you will add a new 5 to the list.

Tips: Never use list as a variable name! It will override the built-in function with the same name, list .
