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...
在最简单的形式下,因为exec()现在是一个函数,而不是语句,2to3会把这个字符串形式的代码用括号围起来。 Python 2里的exec语句可以指定名字空间,代码将在这个由全局对象组成的私有空间里执行。Python 3也有这样的功能;你只需要把这个名字空间作为第二个参数传递给exec()函数。
