Day 29 - Intermediate - Building a Password Manager

# UI SETUP
window = Tk()
window.title("Password Manager")
window.config(padx=50, pady=50)canvas = Canvas(width=200, height=200)
logo_img = PhotoImage(file="logo.png")
canvas.create_image(100, 100, image=logo_img)
canvas.grid(column=1, row=0)# Labels
website_label = Label(text="Website:")
website_label.grid(column=0, row=1)
email_label = Label(text="Email/Username:")
email_label.grid(column=0, row=2)
password_label = Label(text="Password:")
password_label.grid(column=0, row=3)# Entries
website_entry = Entry(width=35)
website_entry.grid(column=1, row=1, columnspan=2)
website_entry.focus()
email_entry = Entry(width=35)
email_entry.grid(column=1, row=2, columnspan=2)
email_entry.insert(0, "angela@gmail.com")
password_entry = Entry(width=21)
password_entry.grid(column=1, row=3)# Buttons
generate_button = Button(text="Generate Password", command=generate_password)
generate_button.grid(column=2, row=3)
add_button = Button(text="Add", width=36, command=save)
add_button.grid(column=1, row=4, columnspan=2)

224. Save Data to File

def save():  website = website_entry.get()  email = email_entry.get()  password = password_entry.get()  with open("data.txt", "a") as file:  file.write(f"{website} | {email} | {password}\n")  website_entry.delete(0, END)  password_entry.delete(0, END)

225. Tkinter Messagebox

tkinter.messagebox

信息消息框

提示框（返回 ok）：showinfo(title, message)
警告框（返回 ok）：showwarning(title, message)
错误框（返回 ok）：showerror(title, message)

疑问消息框

是/否（返回 yes/no）：askquestion(title, message)
是/否（返回 True/False）：askyesno(title, message)
确定/取消（返回 True/False）：askokcancel(title, message)
重试/取消（返回 True/False）：askretrycancel(title, message)
是/否/取消（返回 True/False/None）：askyesnocancel(title, message)

from tkinter import messageboxdef save():  website = website_entry.get()  email = email_entry.get()  password = password_entry.get()  if len(website) == 0 or len(email) == 0 or len(password) == 0:  messagebox.showinfo(title="Oops", message="Please make sure you haven't left any fields empty.")  else:  is_ok = messagebox.askokcancel(title=website,message=f"These are the details entered: \n"f"Email: {email} \n"   f"Password: {password} \n"f"Is it ok to save?") if is_ok:  with open("data.txt", "a") as file:  file.write(f"{website} | {email} | {password}\n")  website_entry.delete(0, END)  password_entry.delete(0, END)

226. Generate and Copy Password

pyperclip

from random import choice, randint, shuffle
import pyperclipdef generate_password():  letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']  numbers = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']  symbols = ['!', '#', '$', '%', '&', '(', ')', '*', '+']  password_letters = [choice(letters) for _ in range(randint(8, 10))]  password_symbols = [choice(symbols) for _ in range(randint(2, 4))]  password_numbers = [choice(numbers) for _ in range(randint(2, 4))]  password_list = password_letters + password_symbols + password_numbers  shuffle(password_list)  password = "".join(password_list)  password_entry.delete(0, END)password_entry.insert(0, password)  pyperclip.copy(password)

227. Complete Password Manager Project
