Python零基础7：解题思路-time、random模块、格式化字符串

解题思路

1.明确项目目标
2.分析过程，拆解项目
3.逐步执行，代码实现

明确项目目标

# 你想制作一个人机PK小游戏，最后想达到这样的效果

分析项目，拆解过程

# 对于新手来说，层层递进，难度不断增加是个不错的选择
# 拆解项目，从最简单过程开始，不断突破

逐步执行，代码实现

版本1.0：自定属性，人工PK

# 用最基础的思路将项目搭起来
# 新知识：time模块
import time
print('【玩家】\n血量：100\n攻击：50')  
print('------------------------') 
time.sleep(1.5) 

print('【敌人】\n血量：100\n攻击：30')
print('------------------------')
time.sleep(1.5) 

print('你发起了攻击，【敌人】剩余血量50')  
print('敌人向你发起了攻击，【玩家】剩余血量70') 
print('------------------------')
time.sleep(1.5) 

print('你发起了攻击，【敌人】剩余血量0')  
print('敌人向你发起了攻击，【玩家】剩余血量40')
print('-----------------------')
time.sleep(1.5) 

print('敌人死翘翘了，你赢了！') 

版本2.0：随机属性，自动PK

# 为达到版本2.0需要的知识通过网络搜索来完成
# time、random模块
import time
import random
enemy_lelf = random.randint(100,150)
player_lelf = random.randint(100,150)
enemy_attack = random.randint(30,50)
player_attack = random.randint(30,50)

print('【玩家】\n血量：'+str(enemy_lelf)+'\n攻击：'+str(enemy_attack))  
print('------------------------') 
time.sleep(1.5) 

print('【玩家】\n血量：'+str(player_lelf)+'\n攻击：'+str(player_attack))
print('------------------------')
time.sleep(1.5) 

while enemy_lelf >= 0 and player_lelf >= 0:
    enemy_lelf = enemy_lelf - player_attack
    player_lelf = player_lelf - enemy_attack

    print('你发起了攻击，【敌人】剩余血量'+str(enemy_lelf)) 
    print('敌人向你发起了攻击，【玩家】剩余血量'+str(player_lelf)) 
    print('------------------------')
    time.sleep(1.5) 

if enemy_lelf <= 0 and player_lelf > 0:
    print('玩家赢得胜利')
elif enemy_lelf > 0 and player_lelf <= 0:
    print('敌人赢得胜利')
else:
    print('打成平局')

版本3：打印成果，三局两胜

# 知识点：time模块、random模块、for循环、while循环、格式化字符串、if……ellf……else
# 最重要的是对于工作的拆解，从易到难进行
# 新知识点：格式化字符串，%可以被看成图书馆占位置的书，%s %f %d
