    "sudo -H -u edxapp bash"
    "source /edx/app/edxapp/edxapp_env"
    "python"
    ">>> import openpyxl"
    • If this runs successfully: you already have openpyxl installed. You can proceed to the actual product installation in the next subsection.

      Quit python shell by typing

      "quit()"

      Run the following command to return to the user edx

      "exit"
    • If not: run the command

      "quit()"

      and proceed with installing openpyxl.

  2. Installing openpyxl

    You should still be logged in to user edxapp. Run the following command

    "sudo pip install openpyxl"

      text appears at various places such as the title of the tab or browser, or in the navigation pane. Recommended max length is 140 characters.

      • Question text: This text is the actual question. This can be elaborate, and there is no limit on the maximum length.

      Recommended max length is 500 characters. If the required question statement exceeds this limit, it is recommended that the question statement is included in the question file that is to be uploaded, and a shorter question text be put in this field.

      • Maximum score: This field requres you to enter the score you want students to be graded out of. This need not be the

      maximum attainable score. The students will be assigned grade for this problem as a percentage out of this value. For example, if the maximum attainable score is 25 but you want any score above 20 to be given full credit (100% credit) for this problem, you enter the value 20 in this field. This value has to be an integer.

      • Problem Weight: This is the weightage of this problem in this assessment type. The sum of weightages of all

      problems in a particular assessment must be equal to 1. If you are unsure, we recommend you have this value as 1.0. This field accepts decimal values.

      • Maximum attempts permitted: This value corresponds to the maximum number of submission a student is allowed to make

      for this problem. Leave this value blank if you don't want to limit the number of submissions. Enter positive values only.
