python快速入门第二版答案 python快速编程入门第二版

一、代码练习

第二章动手练习：

message = "2022.5.31 星期二 雨" \
          "\n请继续坦坦荡荡的微笑面对五颜六色的生活" \
          "\n是的，可以五颜六色" \
          "\n不是乱七糟八~"
print(message)

 

（运行成功！）

message = "今天天气不好，所以心情也不好"
print(message)
message = "没关系，我猜是因为今天值得被记住~"
print(message)

name = "Eric"
# name = input() 与用户简单的交互
sayhi = f"Hello {name},would you like to learn some Python today?"
print(sayhi)

name = "fuYoujing"
print(name)
print(name.title())
print(name.upper())
print(name.lower())

Myfavorite = '《牧羊少年奇幻之旅》中曾说过,' \
             '\n"当你真心想做一件事的时候，' \
             '全宇宙都会联合起来帮助你"' \
             '\n请大胆的去追寻你的热爱吧！！' \
             '\n我相信你所热爱的值得你去追寻♥'
print(Myfavorite)

book = "《牧羊少年奇幻之旅》"
pick = "当你真心想做一件事的时候，全宇宙都会联合起来帮助"
hope = "请大胆的去追寻你的热爱吧！！" \
       "\n我相信你所热爱的值得你去追寻♥"
message = f'{book}曾说过，\n"{pick}",\n{hope}'
print(message)

name = " \t  jing jing    \n"
print("未去除空白:",name)
print("去除开头空白:",name.lstrip())
print("去除末尾空白:",name.rstrip())  # 换行也被去除掉了
print("去除开头和末尾空格:",name.strip())
print("\n大功告成~")

print(2+6)
print(10-1+5-6)
print(24/3) #将任意两个数相除时，结果总是浮点数，即便这两个数都是整数且能整除
print(1*8)
print(5*8/5)
print(80%9) # 模运算，只显示余数

Ilike = int(4) # Ilike = 4  #设置我喜欢的数字
Myanswer = f"{Ilike} is my favourite number."
question = "Which number do I like? " \
           "Now you can have a guess!!" \
           "\nYour answer:"
print(question)
youranswer = input()  # 获取用户输入答案，
youranswer=int(youranswer) # 并转换为整数

# if-else判断答案是否正确 try1
if youranswer == Ilike:
    print("Oh，Congratulations！！you guessed it!")
else:
    print("It's a pity.")
    print(Myanswer)

# while判断答案是否正确以及是否继续猜 try2 （CTRL / 快速注释）（貌似不太会，有待完善,但成功啦）
# 当你的答案与我的答案不同时进入while循环，对你的答案进行提示
# while youranswer != Ilike:
#     if youranswer < Ilike:
#         print("It's a pity.Your number is below what I like. Let's guess again.")
#         youranswer = input()
#         youranswer = int(youranswer)
#     elif youranswer > Ilike:
#         print("It's a pity.Your number is beyond what I like. Let's guess again.")
#         youranswer = input()
#         youranswer = int(youranswer)
# 当我们答案相等时证明猜对了，也就退出了while循环，输出恭喜你猜对了
# print("Oh，Congratulations！！you guessed it!")

# 思考过程：
# 继续输入之后没办法进入下一个判断，难道是要写进一个循环？
# while循环好像是可以的！While循环不断运行直到指定条件不满足为止，而for循环用于针对集合中的每个元素都执行一个代码块。
