Question

python问题求助大神,急急急!!!

class Water:
def ini(self):
self.temperator=15
self.level="凉水"
def hotup(self):
self.temperator+=10
self.setlevel

def setlevel(self):
if str(self.temperator<=10)and str(self.temperator>=0) :
self.level ="冰水"
elif (self.temperator<=20) and (self.temperator>10) :
self.level ="凉水"
else:
self.level ="好水"
def printl(self):
print(self.level,str(self.temperator))

w=Water
w.hotup
w.printl

为什么运行后什么都没有打印出来？
