[Python知识库]用python模拟千分位函数和弹珠游戏

弹珠游戏?

import random
# method1
light = ''
for i in range(12):
    light = light + str(random.randint(0,1))
else:
# 1表示亮灯，0表示没亮
    print("亮灯情况",light)
location = random.randint(1,12)
print("你打到了第%s个灯"%location)
if  light[location-1] == '1':
    print("恭喜你打中了！")
else:
    print("很遗憾你没有打中")

模拟千分位

number = input("请输入一串数字：")
count = 0       # 标注这串数字的第几位
result = ''     # 用来存储分割好的字符串
if number.isdigit():
    for i in number[::-1]:
        count += 1
        result = i + result
        if count % 3 == 0 and count != len(number):
            result = ',' + result
    else:
        print('千分位格式为：', result)
else:
    print("亲，您的输入不合法，请输入数字哦")

# method2:数字正向
str_number = input("请输入一串数字")


# method3
num = input("请输入一串数字")
turn_num = ""
length = len(num)
i = length -3
