python random string and number code example

Example 1: python random string

import secrets 
secrets.token_hex(nbytes=16)

# this will produce something like 
# aa82d48e5bff564f3221d02194611c13

Example 2: generate random string python

import string
import random

length=5
#python2
randomstr = ''.join(random.sample(string.ascii_letters+string.digits,length))


#python3
randomstr = ''.join(random.choices(string.ascii_letters+string.digits,k=length))

Example 3: how to make a module that generates a random letter in python

# -random letter generator-
import string
var1 = string.ascii_letters

import random
var2 = random.choice(string.ascii_letters)
print(var2)

Example 4: python generate random string with lenght

import random
import string

def randStr(chars = string.ascii_uppercase + string.digits, N=10):
	return ''.join(random.choice(chars) for _ in range(N))

# default length(=10) random string
print(randStr())
# random string of length 7
print(randStr(N=7)) 
# random string with characters picked from ascii_lowercase
print(randStr(chars=string.ascii_lowercase))
# random string with characters picked from 'abcdef123456'
print(randStr(chars='abcdef123456'))

Example 5: python generate random string

''.join(random.choice(string.ascii_uppercase + string.digits) for _ in range(N))
