python 的err輸出BaseException

try:
print('try...')
r = 10 / 0
print('result:', r)
except BaseException as e:
print('except:',e)
finally: ##能夠添加，或者刪除，都會執行。

print('finally...')

print('END')

此外，若是沒有錯誤發生，能夠在except語句塊後面加一個else，當沒有錯誤發生時，會自動執行else語句：

try:
    print('try...')
    r = 10 / int('2')
    print('result:', r)
except ValueError as e:
    print('ValueError:', e)
except ZeroDivisionError as e:
    print('ZeroDivisionError:', e)
else:
    print('no error!')
finally:
    print('finally...')
print('END')
