Units become even more powerful and fun when connected with a library that can convert between units. One such library is pint. With pint installed (python -m pip install Pint), you can convert the volume to cubic inches or gallons, for example: Python >>> import pint >>> ureg = pi...

在Python 2里,如果你使用一个逗号(,)作为print语句的结尾,它将会用空格分隔输出的结果,然后在输出一个尾随的空格(trailing space),而不输出回车(carriage return)。在Python 3里,通过把end=' '作为一个关键字参数传给print()可以实现同样的效果。参数end的默认值为'\n',所以通过重新指定end参数的值,可以取消在...
