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
try:
x = int(input('input x:'))
y = int(input('input y:'))
print('x/y = ',x/y)
except ZeroDivisionError: #捕捉除0异常
print("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
print("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")
注意是except而不是catch,写顺手容易写成catch
