Okay so most of us do not know how to generate random strings which include letters and digits. This can be really useful for generating a password or something else just use your evil mind. Okay so how do we generate a random string. Have you ever heard of the string module available in python ? The chances are that you have not heard about it. So what does this module provide us ? Okay here you go lets understand this module by example:
# first we have to import random module as this # provides the backbone for our random string # generator and then we have to import the string # module. >>> import random >>> import string # now lets see what this string module provide us. # I wont be going into depth because the python # documentation provides ample information. # so lets generate a random string with 32 characters. >>> random = ''.join([random.choice(string.ascii_letters + string.digits) for n in xrange(32)]) >>> print random '9fAgMmc9hl6VXIsFu3ddb5MJ2U86qEad' >>> print len(random) 32
Another example with a function:
>>> import string >>> import random >>> def random_generator(size=6, chars=string.ascii_uppercase + string.digits): ... return ''.join(random.choice(chars) for x in range(size)) ... >>> random_generator() 'G5G74W' >>> random_generator(3, "6793YUIO") 'Y3U'
So thats it for now. If you want to further explore the string module then go to the official documentation
