零基础入门python 报错问错
这段代码报错：输入>>> pool=Pool(1,19)
>>> pool.print_num()
Traceback (most recent call last):
File "<pyshell#7>", line 1, in <module>
pool.print_num()
File "E:/python/test1.py", line 15, in print_num
print("水池里总共有乌龟%d只，小鱼%d条！"%(self.trutle.num,self.fish.num))
AttributeError: 'Pool' object has no attribute 'trutle'
>>>
源码如下：
class Trutle:
def __init__(self,x):
self.num=x
class Fish:
def __init__(self,x):
self.num=x
class Pool:
def __init__(self,x,y):
self.trurle=Trutle(x)
self.fish=Fish(y)
def print_num(self):
print("水池里总共有乌龟%d只，小鱼%d条！"%(self.trutle.num,self.fish.num))
class Trutle:
def __init__(self,x):
self.num=x
class Fish:
def __init__(self,x):
self.num=x
class Pool:
def __init__(self,x,y):
self.trurle=Trutle(x)
self.fish=Fish(y)
def print_num(self):
print("水池里总共有乌龟%d只，小鱼%d条！"%(self.trutle.num,self.fish.num))
我标红的地方应该改为 trutle emm，你应该知道乌龟的英文单词是turtle不是trutle的吧……
