trying to build a random password generator (without library random)

Question

How do I convert the returned remainder into characters from my list? (trying to build a random password generator)

Here’s what I have so far:

import time

seconds = time.time() 
print(seconds)

x = float(7) 
y = seconds 
print(y % x)

savage = (y % x) 
print(str(savage), type(savage))

list = ['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','!','@','#','$','0','1','2','3','4','5','6','7','8','9']
new = str(list).join(str(savage))

I’m trying to figure out a way to use the returned remainder from (x % y) to print different characters from my list. I’m thinking that a way to convert the returned remainder to characters in my list would be to print a new set of characters each time the program is run since the seconds is always changing with time.

Without using the library random, here’s one way to do it. I’ve used the number itself to generate an index between 0 and 65, to determine the character in lis. However the password length varies between 15 and 18.

import time

lis = ['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','!','@','#','$','0','1','2','3','4','5','6','7','8','9']

#try to generate 10 random passwords:
for _ in range(10):
    y = time.time() 
    # print(y)
    savage = y % 7
    savage = str(savage).replace('.', '')
    # print(savage)

    pw = ''
    n = len(savage)
    for i in range(n):
        if int(savage[i]) <= 5 and i <= 15:    #max idx is 50+15
            idx = int(savage[i])*10 + i
            pw += lis[idx]
        else:
            idx = (int(savage[i])-5)*10 + i
            pw += lis[idx]
    print(n, pw)

Output:
