How to generate password using python?

random: 
Python has a built-in module that you can use to make random numbers.
The random module has a set of methods:

  • random(): Returns a random float number between 0 and 1
  • sample(): Returns a given sample of a sequence
  • shuffle(): Takes a sequence and returns the sequence in a random order
  • choice(): Returns a random element from the given sequence
  • choices(): Returns a list with a random selection from the given sequence
  • randint(): Returns a random number between the given range
  • uniform(): Returns a random float number between two given parameters

array:
An array is a collection of items stored at contiguous memory locations. 
This module defines an object type which can compactly represent an array of basic values: characters, integers, floating point numbers.

import random
import array

#  password length
MAX_LEN = 12


DIGITS = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
LOCASE_CHARACTERS = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h',
'i', 'j', 'k', 'm', 'n', 'o', 'p', 'q',
'r', 's', 't', 'u', 'v', 'w', 'x', 'y',
'z']

UPCASE_CHARACTERS = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
'I', 'J', 'K', 'M', 'N', 'O', 'P', 'Q',
'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y',
'Z']

SYMBOLS = ['@', '#', '$', '%', '=', ':', '?', '.', '/', '|', '~', '>',
'*', '(', ')', '<']

# combines all the character arrays above to form one array
COMBINED_LIST = DIGITS + UPCASE_CHARACTERS + LOCASE_CHARACTERS + SYMBOLS

# randomly select at least one character from each character set above
rand_digit = random.choice(DIGITS)
rand_upper = random.choice(UPCASE_CHARACTERS)
rand_lower = random.choice(LOCASE_CHARACTERS)
rand_symbol = random.choice(SYMBOLS)

# combine the character randomly selected above

temp_pass = rand_digit + rand_upper + rand_lower + rand_symbol



# the password length by selecting randomly from the combined

for x in range(MAX_LEN - 4):
temp_pass = temp_pass + random.choice(COMBINED_LIST)

# changing the position of the elements of the sequence.

temp_pass_list = array.array('u', temp_pass)
random.shuffle(temp_pass_list)

# traverse the temporary password array and append the charsto form the password
password = ""
for x in temp_pass_list:
password = password + x
# print out password
print(password)
