自己在编译器上写的时候没注意,self.score返回了函数而不是属性,于是出现recursionerror
class Student():
@property
def score(self):
return self.score
@score.setter
def score(self,value):
if not isinstance(value,int):
raise ValueError('Bad Value')
if value < 0 or value > 100:
raise ValueError('Bad Value')
self.score = value
if __name__ == '__main__':
s = Student()
s.score = 88
print(s.score)
RecursionError: maximum recursion depth exceed
搜到一个处理方法:http://blog.csdn.net/gatieme/article/details/50443905
测试代码:
import sys
def func(depth):
depth += 1
print('Now the depth is %s' % depth)
func(depth) # func递归的调用自己,永不退出,死循环
if __name__ == '__main__':
func(0)
运行结果:
Now the depth is 997 # 好吧比代码作者的少2次
Traceback (most recent call last):
............................
修改Recursion Depth:
import sys
sys.setrecursionlimit(10**5)
再次运行studentproperty.py, RecursionError, Again!
只好检查代码,发现错误,bad brain >*<
self.score ———> self._score
Done!
