"Why does printing the newly created list (word4) gives [None, None] as output?" The remove() method you used inside the comprehension construction returns nothing (None). That is why you get `None` inside <word4>, for when a method returns nothing, a `None` will be there as you ...
Python解释器是负责运行Python脚本的应用程序。 Python解释器可在Read-Eval-Print-Loop(REPL)环境中工作。 读取命令。 评估命令。 打印结果。 循环返回,过程重复进行。 当我们使用exit()或quit()命令时,解释器终止,否则执行将继续进行。 Python解释器以两种方式运行代码: 以脚本或模块的形式。 以在交互式会话中编写的...

Thus, Python does not have the end keyword, since you can omit stop to achieve the same behavior. Try out the following examples of the slice syntax in NumPy: Python In [1]: import numpy as np In [2]: arr_1 = np.arange(1, 7, 2) In [3]: arr_1[1:] Out[3]: array([3...
