很抱歉,我之前提供的Dice类定义存在问题。以下是修正后的Dice类设计:
```python
import random
class Dice:
def __init__(self, sides=6):
self.sides = sides
self.roll_count = 0
self.side_counts = {i: 0 for i in range(1, sides+1)}
def roll(self):
self.roll_count += 1
result = random.randint(1, self.sides)
self.side_counts[result] += 1
return result
def side_count(self, side):
return self.side_counts[side]
def roll_count(self):
return self.roll_count
```
在上面的代码中,我们修复了Dice类的问题。新增了两个实例变量 `roll_count` 和 `side_counts`,用于跟踪骰子的投掷次数和每个面出现的次数。修改了 `roll` 方法,使其在投掷骰子时更新投掷次数和每个面的计数。
您可以使用上述代码来测试Dice类。例如,您可以按如下方式打印出100次投掷结果并统计每个面的出现次数:
```python
random.seed(0) # 设置随机数种子,以固定结果
d = Dice()
print("-----Roll dice for 100 times-----")
for x in range(100):
r = d.roll()
if x < 10:
print(r, end=",")
print("...")
print("-----Statistics of rolling the dice-----")
for i in range(1, d.sides+1):
side_count = d.side_count(i)
roll_count = d.roll_count()
print(f"Side {i}: {side_count}/{roll_count} = {side_count*100/roll_count:.1f}%")
```
希望这次的设计能满足您的需求!如果还有其他问题,请随时提问。
