Checking for random string in Python [duplicate]

• How do I compute the approximate entropy of a bit string? 6 answers

Is there a library that allows me to check for the randomness of an input string? Something like:

 >>> is_random_str("dfgjfgnsdfj9p5230948hfirif") -> returns True
 >>> is_random_str("Hello theree") -> returns False
