Prompt a user to choose password character combination which could either be digits, letters, This just help to join (like it's name says) all list item returned from random.choices as a single string with no spaces.Īlright, now that we've gone through all code statement, lets' test the application. Join method was passed a result from random.choices (which returns a list as result) and called on an empty string ( ' ' ) that acts as a separator. When calling random.choices we passed printable as the first argument and length (a parameter on our function) as the last argument. The first argument( population ) accepts an iterable and the last argument ( k ) specifies the number of items that will be randomly choosen from the given iterable. Random.choices takes couple of arguments but we are more concerned about the first and last argument. ![]() # generate random password and convert to string TypeError: 'str' object does not support item assignment If printable is passed to random.shuffle() without converting it first to a list, it'll result to a TypeError random.shuffle() takes a list as it's argument and changes the list item position randomly. Shuffling the list makes it difficult to have same password generated twice. Printable variable which holds an alphanumerical value (string: character sequence) is converted to a list (this is compulsory). ![]() # convert printable from string to list and shuffle Those constants are concatenated using python's F string and saved in a variable named printable. We already have some global variables declared, which holds string constants (digits, punctuation, characters(lowercase and uppercase) respectively). ![]() We will now create a python application to create a random password that meets the following constraints: The password is 12 characters long and contains at least one uppercase letter. It should combine random characters, numbers, and symbols. # create alphanumerical from string constants A Python password generator is a simple program that can create random, strong, and secure passwords. The above function is defined with one parameter length which defaults to 8 (the recommended minimum length of a password is 8). Enter fullscreen mode Exit fullscreen mode ![]()
