Python appending list -

trying change list can generate password

passwordlength=int(input('enter how long password')) # user input   x in range(0,passwordlength):                 password=''.join(characters)                        print(password) 

that working now. characters using list. giving me input list repeated input number.

every time try , use append list end going backwards

any appreciated

i think random.sample may want:

from random import sample  passwordlength = int(input('enter how long password')) # user input    password = ''.join(sample(characters,passwordlength)) 

or else take slice passwordlength:

password = ''.join(characters[:passwordlength])  

to validate user input can use try/except , while loop:

from random import sample  while true:     try:         password_length = int(input('enter password length between 1-{}'.format(len(characters)))) # user input         if password_length > len(characters):             print("password long")             continue         password = ' '.join(sample(characters,password_length))         break     except valueerror:          print("please enter digits only") 

if have ints in character list need map str before joining.

password = ' '.join(map(str,sample(characters,password_length)))
