这是一个模拟便签的作品，主要核心代码是写入和读取

代码献上

# 导包
import easygui
import sys
import time
import json

# 开头
print('---------便签本----------')
print('选择数字1写便签 选择数字2查询便签')
print('输入数字3查看所有便签 选择Q退出程序')
# 时间
time_now = time.strftime("%Y-%m-%d", time.localtime())

# 选择方式
mode = ['1', '2', '3', 'Q']
while True:
	answer = easygui.choicebox('请选择', '选择', mode)
	if answer is None:
		sys.exit()
	else:
		if answer == '1':
			content = easygui.enterbox('请输入你想写的便签', '写入')
			info = {'content': str(content), 'time': str(time_now)}
			if content is None:
				sys.exit()
			elif content == '':
				easygui.msgbox('不可以是空字符')
			else:
				with open('content.txt', 'a', encoding='utf-8') as f:
					new_info = json.dumps(info)
					f.write(new_info + '\n')
		elif answer == 'Q':
			sys.exit()
		elif answer == '2':
			with open('content.txt', 'r', encoding='utf-8') as f:
				data = f.readlines()
			if not data:
				easygui.msgbox('便签为空')
			else:
				new_data_list = []
				for c in data:
					new_data = c.strip()
					new_data_list.append(json.loads(new_data))
				num = ['']
				for i in range(0, len(new_data_list)):
					num.append(i + 1)
				choice_num = easygui.choicebox('请选择你要查询的便签', '选择', num)
				if choice_num is None:
					sys.exit()
				elif choice_num == '':
					easygui.msgbox('你还真选空字符啊')
				else:
					easygui.msgbox('时间: ' + str(new_data_list[int(choice_num) - 1]['time']) + '  内容: ' + str(new_data_list[int(choice_num) - 1]['content']))
		elif answer == '3':
			with open('content.txt', 'r', encoding='utf-8') as f:
				data = f.readlines()
			if not data:
				easygui.msgbox('便签为空')
			else:
				new_data_list = []
				for c in data:
					new_data = c.strip()
					new_data_list.append(json.loads(new_data))

一个需要注意的地方需要创建一个和这个代码项目文件同目录的content.txt文件
