区别:remove()和discard()都是对set集合中的元素进行删除,不同的是,remove()方法删除不存在的元素时会报错,但是discard()方法不会报错 Symmetric_difference() 返回两个集合中不重复的元素集合(对称差集) 注意:会产生新的集合 symmetric_difference_update() 移除两个集合的相同元素,增加不同的元素(对称差集) 注...

C {"15"} D {"12", "18"} 问题解析 1.symmetric_difference()方法的功能是:用于返回所给的两个集合中不重复的元素,即两个集合中都存在的元素不会返回。 2.本题考查symmetric_difference()方法,集合a包含12、15、18三个元素,集合b包含16、15、22三个元素,两个集合都包含15,所以结果为:{"12", "18"...

Address process speed and overhead In the output, you might notice that the PyBind11 extension isn't as fast as the CPython extension, although it should be faster than the pure Python implementation. The major reason for the difference is because of the use of theMETH_O flag. This flag...
