自定义异常求助
class WeightError(Exception):def __init__(self, high, athigh, cehigh):
self.high == high
self.athigh == athigh
self.cehigh == cehigh
try:
weight = int(input('请输入体重 单位（斤）:'))
height = int(input('请输入身高 单位（CM）：'))
if height<30 or height>250:
# 引发异常
raise WeightError (height , 30, 250)
except WeightError as result:
print('你输入的身高为%s，身高请输入在%s到%s范围。'%(self.high, self.athigh ,self.cehigh))
else:
bz_weight = height - 100
cz = ((weight-bz_weight*2)/weight)
if-0.05 <=cz<= 0.05:
print('恭喜您，体重正常达标！')
elif cz>0.05:
print('很遗憾，你的体重超标，请及时锻炼！')
elif cz<-0.05:
print('抱歉,你的体重不达标！')
变量名有点乱
出现的问题是 AttributeError: 'WeightError' object has no attribute 'high'
不知道如何解决 不太理解希望有帮忙解释下报错原因
谢谢拉
self.high == high 不应该是 = 吗？
其它的我看不懂你要干嘛 class WeightError(Exception):
def __init__(self, high, athigh, cehigh):
self.high = high
self.athigh =athigh
self.cehigh =cehigh
if __name__=='__main__':
try:
weight = int(input('请输入体重 单位（斤）:'))
height = int(input('请输入身高 单位（CM）：'))
if height<30 or height>250:
# 引发异常
raise WeightError (height , 30, 250)
except WeightError as result:
print('你输入的身高为%s，身高请输入在%s到%s范围。'%(result.high, result.athigh ,result.cehigh))
else:
bz_weight = height - 100
cz = ((weight-bz_weight*2)/weight)
if-0.05 <=cz<= 0.05:
print('恭喜您，体重正常达标！')
elif cz>0.05:
print('很遗憾，你的体重超标，请及时锻炼！')
elif cz<-0.05:
print('抱歉,你的体重不达标！')
错误：
1、类定义，赋值
2、错误引用，已经对象化的错误对象WeightError，不能用self
