How to get autocomplete in jupyter notebook without using tab?
提问by physicsnoob1000
I would like to get an autocompletion feature in notebooks i.e. when I type something, a dropdown menu appears, with all the possible things I might type, without having to press the tab button. Is there such a thing?
我想在笔记本中获得自动完成功能，即当我输入内容时，会出现一个下拉菜单，其中包含我可能输入的所有可能内容，而无需按下选项卡按钮。有这样的事情吗？
I tried :
我试过 ：
%config IPCompleter.greedy=True
%config IPCompleter.greedy=True
but this requires the tab button to be pressed
但这需要按下选项卡按钮

There is an extension called Hinterlandfor jupyter, which automatically displays the drop down menu when typing. There are also some other useful extensions.
jupyter有一个名为Hinterland的扩展，它在输入时自动显示下拉菜单。还有一些其他有用的扩展。
In order to install extensions, you can follow the guide on this github repo. To easily activate extensions, you may want to use the extensions configurator.
为了安装扩展，您可以按照此github repo上的指南进行操作。要轻松激活扩展，您可能需要使用扩展配置器。

The auto-completion with Jupyter Notebook is so weak, even with hinterland extension. Thanks for the idea of deep-learning-based code auto-completion. I developed a Jupyter Notebook Extension based on TabNine which provides code auto-completion based on Deep Learning. Here's the Github link of my work: jupyter-tabnine.
Jupyter Notebook 的自动完成非常弱，即使有腹地扩展也是如此。感谢基于深度学习的代码自动完成的想法。我开发了一个基于 TabNine 的 Jupyter Notebook 扩展，它提供基于深度学习的代码自动完成。这是我工作的 Github 链接：jupyter-tabnine。
It's available on pypi indexnow. Simply issue following commands, then enjoy it:)
它现在可以在pypi 索引上使用。只需发出以下命令，然后享受它:)
pip3 install jupyter-tabnine
jupyter nbextension install --py jupyter_tabnine
jupyter nbextension enable --py jupyter_tabnine
jupyter serverextension enable --py jupyter_tabnine

As mentioned by @physicsGuy above, You can use the hinterland extension. Simple steps to do it.
正如上面@physicsGuy 所提到的，您可以使用腹地扩展。简单的步骤来做到这一点。
Installing nbextension using conda forge channel. Simply run the below command in conda terminal:
使用 conda forge 通道安装 nbextension。只需在 conda 终端中运行以下命令：
conda install -c conda-forge jupyter_nbextensions_configurator
Next Step enabling the hinterland extension. Run the below command in conda terminal:
下一步启用腹地扩展。在 conda 终端中运行以下命令：
jupyter nbextension enable hinterland/hinterland
That's it, done.
就这样，大功告成。

Without doing this %config IPCompleter.greedy=Trueafter you import a package like numpy or pandas in this way;
import numpy as npimport pandas as pd.
%config IPCompleter.greedy=True在以这种方式导入 numpy 或 pandas 之类的包后，无需执行此操作；
import numpy as npimport pandas as pd.
Then you type in pd.then tap the tab button it brings out all the possible methods to use very easy and straight forward.
然后你输入pd.然后点击标签按钮，它会显示所有可能的方法，使用起来非常简单和直接。

I am using Jupiter Notebook 5.6.0. Here, to get autosuggestion I am just hitting Tab key after entering at least one character.
我正在使用 Jupiter Notebook 5.6.0。在这里，为了获得自动建议，我只是在输入至少一个字符后按 Tab 键。
**Example:** Enter character `p` and hit Tab.
To get the methods and properties inside the imported library use same Tab key with Alice
要获取导入库中的方法和属性，请使用与 Alice 相同的 Tab 键
import numpy as np
np. --> Hit Tab key
