How to print specific output based on condition from variable [closed]

I have a database which looks like this:

And I would like to know how to do a loop to print an output based on some condition.

Here's the output I would like to have (in a txt file for example):

• Name 1

  • Mission 1

    • Sentence1
    • Sentence2

  • Mission 2

    • Sentence3

• Name2

  • Mission3

    • Sentence4

  • Mission4

    • Sentence5

I would like to know how to have an output based on condition on df['Name'] and df['Mission'] in order to have categories but I'm stuck because I never did this kind of condition in a loop.

How can I do that?
