How to make a code in python ursina engine that makes the player jump higher?

I tried to write:
class level_1_class(Entity):
def init(self,**kwargs):
self.player = FirstPersonController()
super().init(parent = self.player)
self.blocks = []
self.player.position.z = 10
self.player.speed = 300
self.player.scale = 90
self.jump = 1000

I was expecting that in my map the player that I made will jump high but it didn’t work(line number 10)
