How to select and add entry to a markdown file in Python?

I have a data.md file as follows:

## intent:greet
- hey
- hello
- hi
- good morning
- good evening
- hey there

## intent:goodbye
- bye
- goodbye
- see you around
- see you later

## intent:affirm
- yes
- indeed
- of course
- that sounds good
- correct

## intent:deny
- no
- never
- I don't think so
- don't like that
- no way
- not really

Now I want to add a new example yes, I affirm to ## intent:affirm so that it becomes as follows:

## intent:affirm
- yes
- indeed
- of course
- that sounds good
- correct
- yes, I affirm

How to achieve this in Python?

Currently, I have no idea on what to start with as I am new to Python, so haven't done anything concrete before seeking help here other than search online for related articles.

You will have to rewrite the file, if you can still access, use copy/paste and in the new file insert the copied file and the parts you want to add. You can't change it because it is a os thing, not python. You may be able to replace the file using the terminal or command line in your OS.

Windows:

REPLACE [Drive:][path]SourceFiles [Drive:][path2] [/A] [/P] [/R] [/W] where:

/A is any missing files

/P is prompt for confirmation

/R is replace even read-only file

/W is wait/pause (originally used for floppy disks)

Linux:

Create and save the new file in the tmp folder, then in the terminal:

cat /tmp/new-file | sudo tee /home/user/(insert more folders and file if needed)

OS X/Mac:

I am unsure how to do this as I have never had a mac, but Google or maybe some communities in StackExchange.

It's a bit more difficult than it seems since you can't just edit a file in python (unless it's at the end). So you can first read the file into an array, and then re-write it. For example:

# Load the file into file_content
file_content = [ line for line in open('data.md') ]

# Overwrite it
writer = open('data.md','w')

for line in file_content:
    # We search for the correct section
    if line.startswith("##"):
        section = line.strip()

    # Re-write the file at each iteration
    writer.write(line)

    # Once we arrive at the correct position, write the new entry
    if section == "## intent:affirm" and line.strip() == "- correct":
        writer.write("- yes, I affirm\n")

writer.close()
