我目前正在学习Python,我不知道我的代码有什么问题,但是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))
任何帮助都将不胜感激!
最佳答案
您在Creating Instance Objects中有错误
在本节中,您没有创建实例,但尝试使用它。
因此,尝试将fish1 = Fish
更改为fish1.bubbles()
。fish1 = Fish
和fish1 = Fish(name, coords)
在构造函数中是必需的。
