random strings - Python [duplicate]

• Random string generation with upper case letters and digits in Python 21 answers

I wanted to know how to print a random string in python. I want this to be a random string like "ayhbygb", and be a random amount of letters long. So like, one time it could print "a", the next time it could print "aiubfiub", or "aiuhiu", etc.

Could someone tell me how this would be done?
