  • When you start writing in a text cell, you will see another box on the right that shows the output.

  • Text cells do not have an arrow on the left for execution.

  • You do not need to memorize HTML code in this section; you can copy/paste it if needed.

    print(True)

Mathematical Equations#

  • A text cell can execute Latex code.

  • If you are not familiar with Latex, feel free to skip this part.

  • The output of $ \int_1^5x^5\,dx$ is \(\int_1^5x^5\,dx\)

Add an Image#

  1. To import an image from your computer to a Colab notebook:

    • Double-click on the text cell to edit it.

    • Click on the image icon in the text cell’s toolbar.

    • Select the image you want to upload.

    • You might see a lengthy and odd-looking text, but you can ignore it.

    • Click outside the text cell to exit the edit mode.

  2. To import an image from an URL use the following markdown syntax: ![](URL)

  • The output of ![](https://www.python.org/static/community_logos/python-logo-master-v3-TM.png) is

  1. If you remove the ! from the code above, it will create a link to the website of the image instead of displaying the image directly in the notebook.

  • The output of [python logo](https://www.python.org/static/community_logos/python-powered-h-100x130.png) is python logo
