Python programming example of a method to generate random usernames and passwords

This article demonstrates an example of how Python can be programmed to generate random usernames and passwords. I will share it with you for your reference as follows:

Plan 1:

import random
global userName,userPassword # For ease of use, it is defined as a global variable 
userName = ''
userPassword = ''
def get_userNameAndPassword():
  global userName, userPassword
  usableName_char = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/" # A character that can be used as a user name 
  usablePassword_char ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890" # The characters that can be used as passwords can be added or subtracted as needed 
  e_userName = [] # define 1 A temporary List variable , use list.append Add character 
  e_userPassword = []
  for i in range(8):
    e_userName.append(random.choice(usableName_char))
  for j in range(6):
    e_userPassword.append(random.choice(usablePassword_char))
  print"e_userName = ", e_userName # Output the username character list
  print"e_userPassword = ", e_userPassword # Output password character list
  userName = ''.join(e_userName)
  userPassword = ''.join(e_userPassword)
try:
  get_userNameAndPassword()
  print " The user name :", userName
  print " password :", userPassword
except Exception, e:
  print e.reason

Program output:

e_userName = ['q', 'M', '2', 'R', 'B', '}', '6', '=']
e_userPassword = ['T', 'O', '4', 'C', 'H', '.']
 The user name : qM2RB}6=
 password : TO4CH.

Option 2 (no intermediate variables) :

#coding=utf-8
import random
global userName,userPassword # It is defined as a global variable for later use 
userName = ''
userPassword = ''
def get_userNameAndPassword():
  global userName, userPassword
  #8 User name and 6 A password 
  userName = ''.join(random.sample("1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/",8))
  userPassword = ''.join(random.sample("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890",6))
try:
  get_userNameAndPassword()
  print " The user name :", userName
  print " password :", userPassword
except Exception, e:
  print e.reason

Program output:

 The user name : GweV?2um
 password : fwiOZL

The second method is often used, which is intuitive and simple.

Note: this example runs normally under python2.7.
