This is a Python GUI program, used for creating and storing online account information in a separate .json file. Let’s see first the UI setup using Tkinter.
💡
UI Setup
The setup is pretty simple and straightforward. At first, we create a canvas with specific dimensions that hold an image. Then, we create ‘Labels’, ‘Entries’, and ‘Buttons’ in order to make the structure of our program. Notice, here that we use the grid component in order to keep things simple.
# ---------------------------- UI SETUP ------------------------------- #
root = Tk()
root.title("Password Manager")
root.config(padx=50, pady=50)
root.iconphoto(False,PhotoImage(file="logo.png"))
# Canvas
canvas = Canvas(width=200, height=200, highlightthickness=0)
img = PhotoImage(file="logo.png")
canvas.create_image(100, 100, image=img)
canvas.grid(column=1, row=0)
# Label
website_label = Label(text="Website:")
website_label.grid(column=0, row=1)
username_label = Label(text="Email/Username:")
username_label.grid(column=0, row=2)
password_label = Label(text="Password:")
password_label.grid(column=0, row=3)
# Entry
website_input = Entry(root, width=23)
website_input.grid(column=1, row=1)
website_input.focus()
username_input = Entry(root, width=37)
username_input.grid(column=1, row=2, columnspan=2)
password_input = Entry(root, width=23)
password_input.grid(column=1, row=3)
# Buttons
btn_search = Button(text="Search", width=10, command=search)
btn_search.grid(column=2, row=1)
btn_password = Button(text="Generate", width=10, command=generate_password)
btn_password.grid(column=2, row=3)
btn_add = Button(text="Add", width=36, command=save)
btn_add.grid(column=1, row=4, columnspan=2)
root.mainloop()
💡
Save Password
Next, we will see the function that is responsible for implementing saving the information the user has entered into the .json file. At first, we store these values in variables and pass them in a dictionary.
With the help of messagebox, we ask the user for confirmation if he is happy with his entry. After that, we open and read that .json file and dump the data there.
# ---------------------------- SAVE PASSWORD ------------------------------- #
def save():
# Fetch values
website_get = website_input.get()
username_get = username_input.get()
password_get = password_input.get()
new_data = {
website_get: {
"email": username_get,
"password": password_get,
}
}
all_get = f"{website_get} | {username_get} | {password_get} \n"
print(all_get)
if len(website_get) == 0 or len(password_get) == 0:
messagebox.showinfo(title="Warning", message=f"Do not leave any fields empty.")
else:
is_ok = messagebox.askokcancel(title=website_get,
message=f"These are the details entered: \nEmail: {username_get}\n Password: {password_get}\n It is ok to save?")
if is_ok:
try:
f = open("data.json", "r")
# Reading old data
data = json.load(f)
except (FileNotFoundError, json.decoder.JSONDecodeError):
f = open("data.json", "w")
json.dump(new_data, f, indent=4)
else:
# Updating old data with new data
data.update(new_data)
f = open("data.json", "w")
# Saving updated data
json.dump(data, f, indent=4)
finally:
website_input.delete(0, END)
username_input.delete(0, END)
password_input.delete(0, END)
💡
Search
Now, it is the turn of the search function. With the help of try and except we can see if there is a data.json file. If it is not a message is displayed to the user and a new file is created.
After that, there is a check if the user has entered a website that exists inside .json. If it is, then the username and the password is being shown as a displayed box. If it is not, an error is shown, informing the user that ‘No details have been found’.
def search():
print(f"Search executed.")
# Fetch values
website_get = website_input.get()
try:
f = open("data.json", "r")
data = json.load(f)
except FileNotFoundError:
messagebox.showinfo(title=f"Not Found", message=f"No Data File Found. Creating it now...")
f = open("data.json", "w")
else:
if website_get in data:
mail = (data[f"{website_get}"][f"email"])
password = (data[f"{website_get}"][f"password"])
messagebox.showinfo(title=f"{website_get}", message=f"Email: {mail}\n Password: {password}")
else:
messagebox.showinfo(title="Error", message=f"No details for {website_get} found.")
```💡
Generate Password
The final function generates a password. A creation of a bunch of lists, each holding different characters, numbers, and symbols. This will help us later with the generation of a random password. We pick a random series of a specific length from these lists and store them in a separate variable.
Then, we append these values to an empty list []. Just a random.shuffle and our password is ready.
def 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 = ['!', '#', '$', '%', '&', '(', ')', '*', '+']
nr_letters = random.randint(8, 10)
nr_symbols = random.randint(2, 4)
nr_numbers = random.randint(2, 4)
password_list = []
for char in range(nr_letters):
password_list.append(random.choice(letters))
for char in range(nr_symbols):
password_list += random.choice(symbols)
for char in range(nr_numbers):
password_list += random.choice(numbers)
random.shuffle(password_list)
password = ""
for char in password_list:
password += char
# print(f"Your password is: {password}")
password_input.insert(0, f"{password}")
