今日のPlaylist:

あれ？書いたつもりだったけど、消えてる😨。

import json



# ---------------------------- SAVE PASSWORD ------------------------------- #
def save():

    website = website_entry.get()
    email = email_entry.get()
    password = password_entry.get()
    new_data = {
        website: {
            "email": email,
            "password": password,
        }
    }

    if len(website) == 0 or len(password) == 0:
        messagebox.showinfo(title="Oops", message="Please make sure you haven't left any fields empty.")
    else:
        try:
            with open("data.json", "r") as data_file:
                #Reading  old data
                data = json.load(data_file)
        except FileNotFoundError:
            with open("data.json", "w") as data_file:
                json.dump(new_data, data_file, indent=4)
        else:
            #Updating  old data with new data
            data.update(new_data)

            with open("data.json", "w") as data_file:
                #Saving  updated data
                json.dump(data, data_file, indent=4)
        finally:
            website_entry.delete(0, END)
            password_entry.delete(0, END)


# ---------------------------- FIND PASSWORD ------------------------------- #
def find_password():
    website = website_entry.get()
    try:
        with open("data.json") as data_file:
            data = json.load(data_file)
    except FileNotFoundError:
        messagebox.showinfo(title="Error", message="No Data File Found.")
    else:
        if website in data:
            email = data[website]["email"]
            password = data[website]["password"]
            messagebox.showinfo(title=website, message=f"Email: {email}\nPassword: {password}")
        else:
            messagebox.showinfo(title="Error", message=f"No details for {website} exists.")

# Buttons
search_button = Button(text="Search", width=13, command=find_password)
search_button.grid(row=1, column=2)
generate_password_button = Button(text="Generate Password", command=generate_password)
generate_password_button.grid(row=3, column=2)
add_button = Button(text="Add", width=36, command=save)
add_button.grid(row=4, column=1, columnspan=2)

window.mainloop()

まずは
else:
　　try:
　　　with open("data.json", "r") as data_file:
　　 #Reading old data
　　　data = json.load(data_file)

これでJsonファイルを作り、その中にあるdataを読む。

except FileNotFoundError:
            with open("data.json", "w") as data_file:
                json.dump(new_data, data_file, indent=4)

でもファイルがなかったらdata.jsonを作って書き込む。

else:
            #Updating  old data with new data
            data.update(new_data)

そのほかの場合は、Updateだね。

with open("data.json", "w") as data_file:
                #Saving  updated data
                json.dump(data, data_file, indent=4)

ファイルを開き、Save。

そしてSearchボタンを作って終了。
