简单罗列一下知识点:
一、基本写法
try:
html = _respose.read().decode('utf-8')
except Exception as e:
pass
捕获多个异常
@H_404_12@try:
x = int(input('input x:'))
y = int(input(input y:))
print(x/y = ',x/y)
except ZeroDivisionError: #捕捉除0异常
"ZeroDivision")
except (TypeError,ValueError) as e: 捕捉多个异常,并将异常对象输出
print(e)
except: 捕捉其余类型异常
it's still wrong")
else:#没有异常时运行
print("no exeception")
finally:#不管有没有异常都要运行
print("end")
else:#没有异常时运行
print("no exeception")
finally:#不管有没有异常都要运行
print("end")
注意是except而不是catch,写顺手容易写成catch
