Python-try異常捕獲

 

 

python中的捕獲異常的用法與c#基本相同，raise就是throw，下面2個例子函數一個系統異常，一個自定義異常。

 

def div(aa,bb):
    try:
        cc=aa/bb
        return cc
    except Exception as e:
        raise
    finally:
        print('finally')

def div1(aa,bb):
    try:
        cc=aa/bb
        return cc
        
    except ZeroDivisionError:
        return '除數不能為0'
    except Exception:
        return '其他類型異常' 
    finally:
        print('finally')
   


try:
    kk=div1(8,0)
    print('try begin')
    print(kk)
    print('try end')

except Exception as e:
    print('ex begin')
    print(e)
    print('ex end')
