collections 模块中的高级数据结构 Python 的 collections 模块提供了标准内建数据类型(如 dict, list, set, tuple)之外的替代容器数据类型。这些特殊化的容器在特定场景下可以提供更优的性能、更简洁的代码或更方便的功能。 2.5 collections.defaultdict:带默认值的字典
Example:if kids had 3 doughnuts, they would set number_of_doughnuts equal to 3, like so: number_of_doughnuts = 3 Assigning this value of “3” to the variable is called initializing. Printing Variables For kids to be able to see the value of their variable when they run their program,...
Virtual environments prevent the issue of running into dependency issues later on. For example, in older projects you might have worked with older versions of thenumpylibrary. Some old code, that once worked beautifully, might stop working once you update its version. Perhaps parts ofnumpyare no...
