We hope these tips will help you enjoy a better code editing experience and make you more confident when sharing your work. Sometimes inaccurate (see examples above) Invoked manually by pressing tab auto-invocation available via Jupyter plugins and extensions In addition to Python, Datalore also offers code completion and syntax highlighting for SQL, R, Scala, and Kotlin. SQL, R, Scala, and Kotlin code autocomplete Datalore will highlight the errors before the execution of the cell, giving you a heads up about any potential problems. Nobody likes to see a red error message in a notebook. Highlighting errors before you execute the code In JupyterLab, classic Find and Replace acts differently: it will replace all entries just like in a text file. It will rename only the variables or functions, leaving text inputs with the same name unchanged. Import optimization in Dataloreĭatalore lets you rename variables and functions using the context menu.

Contextual documentation in Jupyter vs Datalore Other code editing features in Dataloreĭatalore offers a wide variety of quick-fixes, such as import optimization, which helps your code look more professional and clean. Datalore gives you contextual help when you hover over any function/method, and it also suggests method parameters on the fly while you’re typing code. In JupyterLab you can get contextual help by selecting a function and using the context menu. Automatic Python indentation in Datalore Get contextual help In the example below, JupyterLab uses the wrong indentation, which leads to an error when executing the cell: Importance of indentation in Pythonĭatalore corrects the indentation automatically, ensuring your code will be executed without errors. Let’s take a look at how indenting works for a simple if clause. It will also take care of small but important things like putting your caret inside the parentheses, making your code less error-prone.Ī Notebook environment will already be preconfigured for you with the top data science packages preinstalled, so you can start writing code in Datalore right away. Code completion in Dataloreĭatalore will automatically invoke code completion options, and it will give you contextual help when specifying method parameters. To avoid this, you can consider trying Datalore – a collaborative data science platform, which is available online for free. Unfortunately, Jupyter doesn’t offer automatic invocation for code completion options, which means you will be pressing the Tab key all the time. Press the Tab key to enable code autocomplete in Jupyter Notebook
Navigate to the one you want with the arrow keys, and hit Enter to choose the suggestion. Jupyter will suggest a few completion options. To enable code autocomplete in Jupyter Notebook or JupyterLab, you just need to hit the Tab key while writing code.
In this blog post we’ll explain 2 ways to avoid this pitfall and access autocompletion and other coding assistance features for your Jupyter notebooks. Writing code in a “plain text”-looking Jupyter notebook, without any coding assistance, can be overwhelming and can definitely slow data scientists down.
