I would like to make a class that returns a pseudo random number generator. I want to save the result of the _rand function in _r but when I call the function _rand(int(time.time())) I get the error message "rand() missing 1 required positional argument: 'seed'". Could someone please explain me what I did wrong.
class PRNG:
import time
_m = 32768
_b = 9757
_c = 6925
def _rand(self, seed):
n = seed % self._m
while True:
n = (n * self._b + self._c) % self._m
yield n
_r = _rand(int(time.time()))
def rand(self) :
return self._r.__next__()
prng = PRNG()
print(prng.rand())
_rand()
takes two arguments; self
and seed
. Specifically you need to provide what instance the method is being called on. Instead of what you have, try defining _r
in a constructor
def __init__(self):
self._m = 32768
self._b = 9757
self._c = 6925
self._r = self._rand(int(time.time()))
