python - 尝试并简化入门

有没有办法简化代码流，使busy = 0和print busy不必出现两次？

busy = 1
try:
    print 1/0
    busy = 0
    print busy
except:
    busy = 0
    print busy
    raise

最佳答案

您可以将其放入finally子句中：

try:
    print 1/0
except:
    raise
finally:
    busy = 0
    print busy

但是正如@Ryan在评论中提到的，现在except:子句中有一些无用的代码。所以你可以做：

try:
    print 1/0
finally:
    busy = 0
    print busy
