我目前正在学习
Python,我不明白我的代码有什么问题,但PyCharm一直给我以下错误:
Traceback (most recent call last): File "C:/Users/Sam/PycharmProjects/untitled1/app.py",line 5,in <module> fish1.bubbles() TypeError: bubbles() missing 1 required positional argument: 'self'
这是我的代码:
import random from Fish import Fish fish1 = Fish fish1.bubbles() fish1.name = input("enter the name of your fish: ") fish1.coords = ("({0},{1})".format(random.randint(1,100),random.randint(1,100))) print("The fish's name is {0},and it is swimming at co-ordinates{1}".format(fish1.name,fish1.coords))
这是我的Fish.py文件:
class Fish: def __init__(self,name,coords): self.name = name self.coords = coords def bubbles(self): print("{0} blew some bubbles".format(self))
任何帮助,将不胜感激!
解决方法
您在
Creating Instance Objects中有错误
在本节中,fish1 = Fish您没有创建实例,但尝试使用fish1.bubbles().
所以尝试改变fish1 = Fish to fish1 = Fish(name,coords).
