python做一个登录注册界面的方法:
一、登录界面
1、首先初始化一个window界面
window = tk.Tk() window.title('Welcome to Mofan Python') window.geometry('450x300') . . . window.mainloop()
2、界面需要一个欢迎的logo,主要使用画布实现
#welcome image #创建一个200X500的画布 canvas = tk.Canvas(window,height = 200,width = 500) #logo的路径 image_file = tk.PhotoImage(file = 'E:\\\\welcome.gif') #什么位置插入logo图片 image = canvas.create_image(0,0,anchor = 'nw',image = image_file) canvas.pack(side = 'top')
3、接下来主要是登录界面的代码实现
tk.Label(window,text = 'Username:').place(x = 50,y = 150) tk.Label(window,text = 'Password:').place(x = 50,y = 190) var_usr_name = tk.StringVar() #默认值为MrZhangxd@python.com var_usr_name.set('MrZhangxd@python.com') var_usr_pwd = tk.StringVar() entry_usr_name = tk.Entry(window,textvariable = var_usr_name) entry_usr_name.place(x = 160,y = 150) entry_usr_pwd = tk.Entry(window,textvariable = var_usr_pwd,show ='*') entry_usr_pwd.place(x = 160,y = 190)
4、登录和注册按钮的实现代码
#Login and Sign up button # command = usr_login 调用usr_login函数 btn_login = tk.Button(window,text = 'Login',command = usr_login) btn_login.place(x = 170,y = 230) btn_sign_up = tk.Button(window,text = 'Sign up',command = usr_sign_up) btn_sign_up.place(x = 270,y = 230)
5、进行登录判断代码:主要用函数判断
声明usr_login函数
def usr_login(): usr_name = var_usr_name.get() usr_pwd = var_usr_pwd.get() try: with open('usrs_info,pickle','rb') as usr_file: usrs_info = pickle.load(usr_file) except FileNotFoundError: with open('usrs_info','wb') as usr_file: usrs_info = {'admin':'admin'} pickle.dump(usrs_info,usr_file) if usr_name in usrs_info: if usr_pwd == usrs_info[usr_name]: tk.messagebox.showinfo(title = 'Welcome',message = 'How are you?' + usr_name) else: tk.messagebox.showinfo(message = 'Error,your password is wrong,try again.') else: is_sign_up = tk.messagebox.askyesno('Welcome','You hava not sign up yet.Sign up today?') if is_sign_up: usr_sign_up()
登录用户不存在需要注册
二、注册界面
差不多和登录界面一样,然后不进行细细的说明了,有不懂地方的可以给下文邮件地址发邮箱。
def usr_sign_up(): def sign_to_Mofan_Python(): np = new_pwd.get() npf = new_pwd_confirm.get() nn = new_name.get() with open('usrs_info','rb') as usr_file: exist_usr_info = pickle.load(usr_file) if np!= npf: tk.messagebox.showerror('Error','Password and confirm password must be the same!') elif nn in exist_usr_info: tk.messagebox.showerror('Error','The user has already signed up!') else: exist_usr_info[nn] = np with open('usrs_info.pickle','wb') as usr_file: pickle.dump(exist_usr_info,usr_file) tk.messagebox.showinfo('Welcome','You have successfully signed up!') window_sign_up.destroy() window_sign_up = tk.Toplevel(window) window_sign_up.geometry('350x200') window_sign_up.title('Sign up window') new_name = tk.StringVar() new_name.set('MrZhangxd@python.com') tk.Label(window_sign_up,text = 'Username:').place(x = 10,y = 10) entry_new_name = tk.Entry(window_sign_up,textvariable = new_name) entry_new_name.place(x = 150,y = 10) new_pwd = tk.StringVar() tk.Label(window_sign_up,text = 'Password:').place(x = 10,y = 50) entry_new_pwd = tk.Entry(window_sign_up,textvariable = new_pwd,show = '*') entry_new_pwd.place(x = 150,y = 50) new_pwd_confirm = tk.StringVar() tk.Label(window_sign_up,text = 'Confirm password:').place(x = 10,y = 90) entry_comfirm_sign_up = tk.Entry(window_sign_up,textvariable = new_pwd_confirm,show = '*') entry_comfirm_sign_up.place(x = 150,y = 90) btn_comfirm_sign_up = tk.Button(window_sign_up,text = 'Sign up',command = sign_to_Mofan_Python) btn_comfirm_sign_up.place(x = 150,y = 130)
