问题是这样的：
看了小甲鱼老师第37讲的课后作业（乌龟吃鱼），我想自己修改一下。
修改后如下：

import random as r
import easygui as g
legal_x = [0,10]
legal_y = [0,10]
class Turtle:
def __init__(self):
self.power = 100
self.x = r.randint(legal_x[0],legal_x[1])
self.y = r.randint(legal_y[0],legal_y[1])
def move(self,direction):
if direction == '向前':
new_y = self.y + 1
if new_y > legal_y[1]:
self.y = legal_y[1] - (new_y - legal_y[1])
else:
self.y = new_y
if direction == '向后':
new_y = self.y - 1
if new_y < legal_y[0]:
self.y = legal_y[0] - (new_y - legal_y[0])
else:
self.y = new_y
if direction == '向左':
new_x = self.x + 1
if new_x > legal_x[1]:
self.x = legal_x[1] - (new_x - legal_x[1])
else:
self.x = new_x
if direction == '向右':
new_x = self.x - 1
if new_x < legal_x[0]:
self.x = legal_x[0] - (new_x - legal_x[0])
else:
self.x = new_x
self.power -= 1
return (self.x,self.y)
def eat(self):
self.power += 20
if self.power > 100:
self.power = 100
class Fish:
def __init__(self):
self.x = r.randint(legal_x[0],legal_x[1])
self.y = r.randint(legal_y[0],legal_y[1])
def move(self):
new_x = self.x + r.choice([-1,0,1])
new_y = self.y + r.choice([-1,0,1])
if new_x < legal_x[0]:
self.x = legal_x[0] - (new_x - legal_x[0])
elif new_x > legal_x[1]:
self.x = legal_x[1] - (new_x - legal_x[1])
else:
self.x = new_x
if new_y < legal_y[0]:
self.y = legal_y[0] - (new_y - legal_y[0])
elif new_y > legal_y[1]:
self.y = legal_y[1] - (new_y - legal_y[1])
else:
self.y = new_y
return (self.x,self.y)
turtle = Turtle()
fish = []
for i in range(10):
newfish = Fish()
fish.append(newfish)
a = '嗯~哼~哼哼哼~~~'
b = '小乌龟，爬呀爬~~~'
c = '小鱼小鱼快出来~~~'
d = '好无聊啊~~~'
e = '妈妈在哪里呢~~~'
f = '龟生的意义是什么。。。'
g = '有点饿~~~'
h = '谁来陪我玩。。。'
say = r.choice([a,b,c,d,e,f,g,h])
while True:
if not len(fish):
g.msgbox('鱼儿被吃完了，游戏结束。')
break
if not turtle.power:
g.msgbox('乌龟体力耗尽，游戏结束。')
break
direction = g.buttonbox(say+'乌龟还有%d点体力\n\n要怎么游呢？'%turtle.power,choices = ('向前','向后','向左','向右','不玩了'))
if direction == '不玩了':
break
pos = turtle.move(direction)
for each_fish in fish[:]:
if each_fish.move() == pos:
fish.remove(each_fish)
turtle.eat()
g.msgbox('乌龟发现了一条鱼儿\n乌龟吃掉了鱼儿\n还有%d条鱼'%(len(fish)))

复制代码

运行以后出现这个问题：（不会插入图片）
Traceback (most recent call last):
File "C:\Users\Administrator\Desktop\测试.py", line 112, in <module>
direction = g.buttonbox(say+'乌龟还有%d点体力\n\n要怎么游呢？'%turtle.power,choices = ('向前','向后','向左','向右','不玩了'))
AttributeError: 'str' object has no attribute 'buttonbox'

请问改怎样解决？

python提示字符串没有buttonbox方法

是这样的，你向import easygui as g
但是又g = '有点饿~~~'覆盖了g
是变量名相同引起的~
