I am trying to create a password generator and i keep getting this error: "TypeError: can only-CodePudding

I am a beginner and I am trying to create a random password generator. I get a entry box and a button, but after entering a number(the password length) I get an error, it is supposed to return a password.

Full error:

Exception in Tkinter callback

CodePudding user response：

random_password = () is defining an empty tuple, you probably intend to use random_password ='' if you're wanting to append characters to it.

However, better yet would be to use random.choices and str.join:

random_password = ''.join(random.choices(character_list, k=password_length))

CodePudding user response：

Read your error , it says you are trying to add string to a tuple which is causing the exception. If u review your code you can see the problem in the following lines:

    random_password = () # initialized an empty tuple 
    .....
    random_password  = character_list[random.randint(0, 91)] # adding string to the tuple

initialize your "random_password" variable to empty string ("") and you should be good
