JupyterLab - Interface

若要启动一个新的笔记本，请单击所需的内核。在以上屏幕截图中，可以看到一个内核，即 Python3 内核。单击它以启动一个 Python 笔记本。请注意，它的功能类似于我们本教程中所研究的功能。

To start a new notebook, click the desired kernel. In above screenshot, one kernel is seen that is Python3 kernel. Click it to start a Python notebook. Observe that its functionality is similar to the one we have studied in this tutorial.

左边的侧边栏显示按钮用于启动新启动器、添加文件夹、上传文件和刷新文件列表。右侧窗格是主要工作区域，其中笔记本、控制台和终端以标签视图显示。

The left sidebar shows buttons for starting a new launcher, adding a folder, uploading file and refresh file list. The right pane is the main working area where notebook, console and terminals are shown in tabbed view.

若要启动新控制台，请单击左侧边栏中的 + 符号以打开新启动器，然后单击控制台选项。控制台将在右侧窗格的新标签中打开。

To start a new console, click + symbol in the left side bar to open a new launcher and then click the console option. The console will open in new tab on the right pane.

请注意，输入单元格位于底部，但运行后，单元格及其相应的输出单元格将显示在控制台标签的上部。

Note that the input cell is at the bottom, but when it is run, the cell and its corresponding output cell appears in upper part of console tab.

启动器还允许您打开一个文本编辑器和一个可以调用 IPython shell 的终端。

The launcher also allows you open a text editor and a terminal in which IPython shell can be invoked.
