1、 打分实现
#-*- codeing =utf-8 -*-
#@Author:致远
#@File:test.py
#@Software:PyCharm
scores = [] #定义列表存储分数
#n = int(input("评委人数:"))
for i in range(10):
score = float(input(f"请输入第{i+1}名评委的打分:"))#输入分数
while score < 0 or score > 100:
score = float(input("打分错误,请重新打分:"))
scores.append(score)#将打分存入列表中
max_score = max(scores)#取最大值
min_score = min(scores)#取最小值
print(f"去掉一个最低分: {min_score}")
scores.remove(min_score)#去最小值
print(f"去掉一个最高分: {max_score}")
scores.remove(max_score)#去最大值
print("该歌手的得分为: %.2f" % (sum(scores) / len(scores)))#总分
2、猜拳实现:
import random
player =int(input('玩家出拳:0-石头,1-剪刀,2-布:'))
computer = random.randint(0,2) //随机生成0~2的整数
print('电脑出拳:%d' % computer)
if ( (player==0)and(computer==1) or (player==1)and(computer==2) or (player==2)and(computer==0) ):
print('玩家获胜:')
elif player == computer:
print('平局')
3、1-100偶数累加实现:
法一:
i = 1
sum = 0
while i <= 100:
if i%2==0: #判断是否为偶数
sum = sum + i
i += 1
print(sum)
法二:
i = 0 # 初值为0
sum = 0
while i <= 100:
if i%2==0:
sum = sum + i
i += 2 #增量每次加2
print(sum)
4、退出循环:break(终止整个循环)、continue(跳过循环,执行下一条)
continue:
i = 1
while i <= 5:
if i == 4:
print('跳过该次')
i+=1 #不加此语句,会进入死循环
continue
print(i)
i+=1
break:
#break
i = 1
while i <= 5:
if i == 4:
print('退出循环')
break
print(i)
i+=1
5、嵌套循环:
j=0
while j<5:
i = 0
while i<3:
print('我错了')
i+=1
print('写作业')
print('惩罚结束***************************')
j+=1
i变量控制每天做某事做多少次,j变量相当于控制这件事做多少天
