python怎么解决cannot import name 'Die' form 'die' 问题

Question

我的程序有错吗？

Answer 1

同一文件不用import，去掉第7行就能运行了：

from random import randint
class Die():
    
    def __init__(self,num_sides=6):
        self.num_sides = num_sides
        
    def roll(self):
        return randint(1,self.num_sides)
    
die = Die()
results = []
for roll_num in range(100):
    result=die.roll()
    results.append(result)

print(results)
