Generating random Id’s in Python
  • Last Updated : 27 Jan, 2018

In python there are different ways to generate id’s. Let’s see how different types of Id’s can be generated using python without using inbuilt Python libraries.

1. Generating Random Integer as Ids’

Code #1 : Print 10 random values of numbers between 1 and 100.




# Python3 code to demonstrate the
# random generation of Integer id's
  
import random
  
# determines how many values
# will be printed
for x in range(10):
      
    # print 10 random values
    # between 1 and 100
    print (random.randint(1, 101))

Output :

76
72
7
78
77
19
24
23
77
96

 
Code #2 : Print random numbers between 1 and 100 which are multiple of 5.




# Python3 code to demonstrate
# the random generation of id's
# which are multilpe of 5
  
import random
  
# determines how many
# values will be printed
for x in range(10):
          
    # print 10 random values between
    # 1 and 100 which are multiple of 5
    print (random.randint(1, 20) * 5)

Output :



60
30
35
100
85
25
100
20
90
85

 

Drawbacks :

  • Generating Random numbers is not unique, Same number can repeat itself.
  • It generates only Integer values.
  • 2. Generating Random String as Ids’

    Generating Random string id’s consists of letters and digits. This can be useful in generating passwords as its provide the encryption and decryption technique.

    Code #1 : Show how to generate random string id’s.




    # Python3 code to demonstrate the
    # random generation of string id's
      
    import random
    import string
      
    # Generate a random string
    # with 32 characters.
    random = ''.join([random.choice(string.ascii_letters
                + string.digits) for n in range(32)])
      
    # print the random
    # string of length 32
    print (random)

    Output :

    Rf2IdqUNkURNN6mw82kSpyxQe9ib3usX
    

     
    Code #2 : Using Function call




    # Python3 code to demonstrate
    # the random generation of string id's
      
    import random
    import string
      
    # defining function for random
    # string id with parameter
    def ran_gen(size, chars=string.ascii_uppercase + string.digits):
        return ''.join(random.choice(chars) for x in range(size))
      
    # function call for random string
    # generation with size 8 and string 
    print (ran_gen(8, "AEIOSUMA23"))

    Output :

    S2M2IEAO
