使用random.randin时未定义“名称'random'”

Question

我正在编写一个Python脚本，它将从我编写的列表中打印出一个随机值

from random import randint
class_list=[0,1,2,3,4,5,5,6,7,8,9,10,11,12]
people_called=[]
randomized_number = random.randint(0,12)
print "debug number" + str(randomized_number)
print "The student is" + str(class_list[randomized_number])
class_list[randomized_number].append(people_called)

但是当我运行这个文件时

Traceback (most recent call last):
  File "./Code/class list.py", line 4, in <module>
    number = random.randint(0,12)
NameError: name 'random' is not defined

Answer 1

from random import randint从random模块导入randint。也就是说，您可以将其用作randint。如果要将其导入为import random，则必须使用random.randint。
