本文将用tkinter模块来写一个图书管理系统将用户分为管理员和普通用户用户都有首页首页展示天气预报并有公告栏。管理员有权限对用户、图书进行添加、修改、删除等操作。普通用户只有搜索图书的功能。本文几乎涉tkinter的所有组件适合新手练习tkinter欢迎大家的订阅。
运行环境
编译器:PyCharm 2021.2.1 解释器:Anaconda 3.8 pip install opencv-python4.5.5.64 温馨提示最好是在本文所要求环境运行避免程序可能出现报错。
功能图 数据操作
数据操作是对数据进行操作如增删改查用户在界面上的操作实际就是对数据的操作只不过用户看到的是界面只需点点就行了操作更方便更容易因为我们都把功能写好了。
图书数据管理
Book类有7个方法分别为query_book()、add_book()、del_book()、 mod_book()、write_book()、read_book()first_add_book()。 query_book()为查询图书我们只需要把书的id、书名或者作者作为搜索条件将返回列表如果没有数据则返回空列表。 首先我们先获取所有列表的索引然后根据字典取值判断他们是否相等如果相等则添加到列表中否则就不添加。 add_book()添加图书首先调用query_book()函数传入id判断图书是否在书库里如果存在返回False不存在返回True表示可以添加。 del_book()根据传入的书名查找图书找到了就删除没有则不作为。 mod_book()修改图书和add_book()类似也是先查找找到图书根据传入的参数对图书进行修改。 write_book()写入文件将self.books写入文件并保存到本地。 read_book()读取所有的图书。 first_add_book()第一次运行没有图书将自动添加图书并创建文件夹保存数据格式为json。
import json
import os

用户数据管理
用户数据管理和图书数据管理类似这里就不作过多的讲解。看代码。
import json
import os
[{user:, password:, state:},{},][[], []] 学生用户 管理员用户
全部默认字符串
{user:[{}], admin:[{}]}
1 普通用户
2 管理员用户名唯一

借书记录管理
Record类主要函数是estimate_upper_limit()用于判断用户的借书数量当借书数量大于或者等于2时就返回True不允许用户再借书了。其余方法与上文相似看代码。
import os
import jsondef first_run():name record.jsonif not (name in os.listdir()):print(开始初次写入用户信息)with open(rrecord.json, modew, encodingutf-8) as f:f.write(json.dumps([]))class Record:def __init__(self):first_run()self.read_record()def read_record(self):with open(rrecord.json, moder, encodingutf-8) as f:self.record_books json.loads(f.read())def write_record(self):with open(rrecord.json, modew, encodingutf-8) as f:f.write(json.dumps(self.record_books))print(写入记录成功, self.record_books)# 借书上限为2def estimate_upper_limit(self, user):borrow_books []for book in self.record_books:if book[user] user:if int(book[book_num]) 1:return Trueelse:borrow_books.append(book)if len(borrow_books) 2:return Truereturn False# 还书def drop_book(self, book_id, user):all_books []for book in self.record_books:if book[id] book_id and book[user] user:all_books.append(book)if all_books:return all_booksreturn False# 查询用户def query_user(self, user):dance []for o in self.record_books:if o[user] user:dance.append(o)print(dance)return danceif __name__ __main__:record Record()record.write_record()
功能界面
登录界面核心功能check_login()函数用于检查登录是否成功检查是否存在此用户密码错误超过了三次账号就会被封禁需要联系管理员解封。管理员登录则宽松许多可以一直登录直到登录成功。

首页的天气预报需要爬取数据我们选择爬2345的分为两部分第一部分将天气图片爬下来用类名存储图片。第二部分爬取城市天气数据用列表存储且支持搜索城市天气。这爬虫比较简单而且网站也没有什么反爬正常流程走就行了。下面展示部分代码。

普通用户界面
首页、搜索、消息、更改密码这四个界面其实和管理员界面大同小异这里就不过多的讲述了。
其他功能
数字时间显示
我们将用tkinter中的canvas模块来写一个类似数字闹钟的时间显示效果首先我们知道绘制一个数字最多需要七笔比如零假设我们从某一个笔开始如果这个数字有这个一笔那我们就绘制没有就跳过那我们就可以完美的将每一个数字绘制下来。draw_num()绘制单个数字将以上规律复现出来了。
import tkinter
from datetime import datetime
采用24进制 格式12:15
可以采用12小时进制 格式12:15
class Clock:def __init__(self, root, height15, width3, mode24):# 以左上角坐标为准# 画布的宽高self.width widthself.height height# 画布的粗细self.line_distance 5self.root rootself.canvas tkinter.Canvas(root, width150, height60)self.draw_clock()def draw_clock(self):# 删除之前绘制的self.canvas.delete(all)now datetime.now()# 获取时间string now.strftime(%H%M)# 小时self.draw_num(20, 10, int(string[0]))self.draw_num(20 self.height * 2, 10, int(string[1]))# 两个点self.draw_interval(20 self.height * 3.7, 20)self.draw_interval(20 self.height * 3.7, 35)# 分钟self.draw_num(20 self.height * 4.7, 10, int(string[2]))self.draw_num(20 self.height * 6.7, 10, int(string[3]))def draw_num(self, x, y, num0):# 总共分为7笔 每一笔if num in [2, 3, 4, 5, 6, 8, 9]:self.canvas.create_line(x self.height, y self.height, x, y self.height,widthself.width)if num in [0, 4, 5, 6, 8, 9]:self.canvas.create_line(x - self.line_distance, y self.height - self.line_distance,x - self.line_distance, y, widthself.width)if num in [0, 2, 3, 5, 6, 7, 8, 9]:self.canvas.create_line(x, y, x self.height, y, widthself.width)if num in [0, 1, 2, 3, 4, 7, 8, 9]:self.canvas.create_line(x self.line_distance self.height, y,x self.height self.line_distance,y self.height - self.line_distance,widthself.width)if num in [0, 1, 3, 4, 5, 6, 7, 8, 9]:self.canvas.create_line(x self.line_distance self.height,y self.height,x self.line_distance self.height, y self.height * 2,widthself.width)if num in [0, 2, 3, 5, 6, 8, 9]:self.canvas.create_line(x self.height, y self.height * 2,x, y self.height * 2,widthself.width)if num in [0, 2, 6, 8]:self.canvas.create_line(x - self.line_distance, y self.height * 2,x - self.line_distance, y self.height,widthself.width)def draw_interval(self, x, y):self.canvas.create_rectangle(x, y, x 5, y 5, fillblack)if __name__ __main__:root tkinter.Tk()root.geometry(500x500350150)n Clock(root)n.canvas.pack()root.mainloop()
加载画面显示
登录成功后会出现一个加载界面这个效果实现比较简单要用到Progressbar()创建进度条show()函数用for循环不断改变Progressbar()里面的值同时需要更新界面以达到动态显示的效果。当进度条加满时画面结束。
from tkinter_book.other_fun.center_gui import gui_center
import tkinter.ttk
import tkinter
import random
import timeclass Loading(tkinter.Tk):def __init__(self):super(Loading, self).__init__()# 居中显示gui_center(self, 100, 14)# 窗口透明self.attributes(-alpha, 0.8)# 无边框self.overrideredirect(True)self.loading_gui()self.mainloop()# 创建进度条def loading_gui(self):self.pro tkinter.ttk.Progressbar(self, value0, max100, length100)self.pro.pack()self.show()# 动态加载进度条def show(self):v random.randint(1, 5)for i in range(100):v random.randint(1, 16)self.pro.config(valuev)# 更新self.update()time.sleep(0.09)if v 100:print(结束了)self.destroy()returnif __name__ __main__:Loading()
输入框提示词
输入框提示词效果比较简单把Entry重写当光标不在的输入框的时候显示提示词光标在的时候就不显示最后我们还可以获取到输入框的值。
from tkinter import *class NewEntry(Entry):def __init__(self, masterNone, placeholder提示词, colorgrey):super().__init__(master)# 提示输入self.placeholder placeholderself.placeholder_color color# 输入框背景self.default_fg_color self[fg]# 光标聚集self.bind(FocusIn, self.foc_in)# 光标离开self.bind(FocusOut, self.foc_out)self.put_placeholder()# 重写插入提示词def put_placeholder(self):self.insert(0, self.placeholder)self[fg] self.placeholder_color# 光标在的时候 删除提示词def foc_in(self, *args):if self[fg] self.placeholder_color:self.delete(0, END)self[fg] self.default_fg_color# 光标离开插入提示词def foc_out(self, *args):if not self.get():self.put_placeholder()# 获取输入框的值def get_input_box(self):print(self.get())return self.get()
界面居中显示
首先获取屏幕的宽高那我们就有了界面宽高和屏幕的宽高那就很容易就能计算出界面居中的位置。
# 窗口居中
def gui_center(win, width300, height450):# 获取屏幕的宽高screen_width win.winfo_screenwidth()screen_height win.winfo_screenheight()x int(screen_width / 2 - width / 2)y int(screen_height / 2 - height / 2)win.geometry(f{width}x{height}{x}{y})借书时间和还书时间记录
这里用到了time模块用于记录时间根据时间戳来计算还书和借书的时间。
import timeclass ComputingTime:def __init__(self):pass# 返回当前时间def current_time(self):return time.time()# 还书时间def return_book_time(self, days):# 根据天数计算归还时间# print(time.localtime(self.current_time()self.count_second(30)))borrow self.current_time()return borrow self.count_second(days)# 计算十位时间戳def count_second(self, days):return int(days) * 24 * 60 * 60# 判断是否到了还书时间def compare(self, back):current self.current_time()if current back:return Trueelse:return Falseif __name__ __main__:clock ComputingTime()print(clock.return_book_time(20))
公告栏数据操作
公告栏比较简单当第一次运行时会写入数据并保存为json格式。当我们需要对数据进行操作时可以读取或写入以达到重新发布公告栏的效果。
import osdef first_write(txt关注天天501):name 公告栏.txtif not (name in os.listdir()):print(开始初次写入用户信息)with open(name, modew, encodingutf-8) as f:f.write(txt)return# 写入数据
def announcement_write(txt):with open(公告栏.txt, modew, encodingutf-8) as f:f.write(txt)# 读取数据
def announcement_read():with open(公告栏.txt, moder, encodingutf-8) as f:return f.read()
