docs: Initialize internal state of the random number generator.
  
          None or no argument seeds from current time or from an operating
          system specific randomness source if available.
  
          If a is not None or is an int or long, hash(a) is used instead.
          Hash values for some types are nondeterministic when the
          PYTHONHASHSEED environment variable is enabled.
