硬币的投掷概率

硬币投掷的次数越多，正反面的概率越趋向于二分之一。

import random
countback = 0
countfront = 0
a = int(input('输入次数：'))
for i in range(0,a):
    result = random.randint(0,1)
    if result == 0:
        countfront += 1
        print(result)
    else:
        countback += 1
        print(result)
print('结果是')
print('正面：',countfront)
print('反面：',countback)
