在上个假期，我做了一个非常非常妙的Flask项目，名曰Notes，是一个~普普通通的~记事本程序，有登录、注册、添加笔记、删除笔记、编辑笔记等~成千上万~的功能，甚至还有分享这个~高级~功能！该项目是开源的，欢迎大家Fork、Pull Request。对了，走过路过记得给我Star一下哦！

差点忘了，如果自己不想部署的话，可以在这里进行在线体验哦！

这是本项目在Github的项目链接:

等待下载完成后就OK了！！

这个就不多说了，开箱即用。没有函数。

2022 Update：警示后人：不查自带函数的后果很严重！ 额...发现可以把文字转码后+1/-1来实现

最近我才学定义函数，写了一个替换式密码小程序。

1.替换式密码.py

这个程序是可以被调用的，一共有两个函数，分别是jiami"(加密）jiemi（解密）。jiami调用时传入两个参数，第一个是明文，第二个是移位值，传回密文。jiemi调用时也传入两个参数，第一个是密文，第二个是移位值，传回明文。

# 文件名：替换式密码.py
# 包括两个函数
def jiami(ming, yi):
mi = ""
ming\_old\_list = list(ming)
ming = ""
for y in range(0, yi):
for i in ming\_old\_list:

mi += "b"
elif i == "A":
mi += "B"

2.文本替换式加解密.py

这个Python程序可以引导你加/解密

代码来喽！

# 依赖替换式密码
# 文件名：文本替换式加解密.py
import 替换式密码
while True:
print("欢迎使用文本加解密APP！")
print("(1)加密 （2）解密 输入其他内容退出")
m = input("请输入：")
if m == "1":
ming = input("请输入明文：")
while True:
try:
yi = int(input("请输入移位值："))
except ValueError:
print("请输入数字！")
else:
break
print("密文为：%s\\n" % (替换式密码.jiami(ming, yi)))
elif m == "2":
mi = input("请输入密文：")
while True:
try:
yi = int(input("请输入移位值："))
except ValueError:
print("请输入数字！")
else:
break
print("明文为：%s\\n" % (替换式密码.jiemi(mi, yi)))
else:
break

今天天气格外好，于是我们一家打算去莫愁湖公园玩

下午一到莫愁湖公园，我们就买了票进去。首先我们来到了儿童游乐区，然后我们到了河边，这里的景色可真美：远处有一座仿古的房子，旁边有一个喷泉，湖面上有一些仿古游船悠闲地散步，杨柳在眼前摇来摇去，好像在向大家炫耀着它的新芽，偶尔还有几只鸟儿飞过，叽叽喳喳叫几声，我赶紧用相机把这美景记录下来。

再往前走，我们到了游船码头。今天我们租个游船开开？妈妈提议。好！我开得一蹦三尺高，现在的这样游船不好看，要不我们换个码头？反正价格都一样。妈妈同意了。于是我们来到另一个码头租了一艘黄色的四人仿古船。工作人员先教了我们一个操作方法，然后我们使穿上救身衣，开始开船着先由爸爸开船，我乘机看了一下河底哇！真是太美了！每一片水草的叶子上都有一个红点，好像是人为点的一样！然后我又开了一会儿船，这时爸爸告诉我：还有5分钟超时！于是我向码头开去。

过了一会儿，我们还好了船，又参观了莫愁女像，就回家了。莫愁湖太！美！了！
