for key in students_1.keys(): print(key) 1. 2. 在遍历字典时,如果没有指明方法,会默认遍历所有的键,即下面这种: for key in students_1: print(key) 1. 2. 用方法values()遍历字典中的所有值: for value in students_1.values(): print(value) 1. 2. 如果存在重复值,而又想剔除它们,可以用s...

Data that is being represented in a region of the colormap that is at a plateau or kink will lead to a perception of banding of the data in those values in the colormap (see [mycarta-banding] for an excellent example of this). 代码语言:javascript 代码运行次数:0 运行 AI代码解释 plot...
Reading values Several representations are accessible: >>> c.hex '#00f' >>> c.hsl # doctest: +ELLIPSIS (0.66..., 1.0, 0.5) >>> c.rgb (0.0, 0.0, 1.0) And their different parts are also independently accessible, as the different amount of red, blue, green, in the RGB format: ...
