我们从Python开源项目中，提取了以下4个代码示例，用于说明如何使用random.paretovariate()。
def sample(self): return random.paretovariate(self.alpha)
def _execute(self, sources, alignment_stream, interval): if alignment_stream is None: raise ToolExecutionError("Alignment stream expected") for ti, _ in alignment_stream.window(interval, force_calculation=True): yield StreamInstance(ti, random.paretovariate(alpha=self.alpha))
def _resource_pr(self, resource, x, y, distance, deposit): seed("{}.{}".format(x, y)) if resource == 'clay': v = paretovariate(2) / (distance + 1) return v if v > .2 else 0 if resource == 'elevation': return paretovariate(4) / (distance + 1) if resource == 'ore': dx, dy, dr = deposit angle = math.atan2(dy - y, dx - x) % math.pi diff = .5 / (angle - dr + .5) v = paretovariate(2) / (distance + 1) * diff return v if v > .4 else 0
