Set simple Markdown script in python

Question

I am trying to use Markdown with python, but I am having trouble:

import markdown

layers = [1,2,3]
lr = 2
dir = 'result'

with open('readme.md', 'a+') as f:
    f.write('## Layer sizes')
    for layer in layers:
        f.write('* {}'.format(layer))
    f.write('## Learning rate is {}'.format(lr))
    f.write('## Init')
    f.write('Add note about init')
    markdown.markdownFromFile(input=f, output=dir+'/out.html')

I get the error can't concat str to bytes which is a common question, for example here. I tried different arrangement of changing to bytes or back to string, but I still can't get it to work; instead I just get a slightly different error, but the whole theme is str and byte compatibility. I'd appreciate any help.

You should add which line exactly causes the problem

Well it seems like, markdown package works only on Binary files instead of Text files, so encode the individual strings that you're writing to the readme.md file and pass in file pointers as the input and output instead of just the name of the file.

import markdown as md

layers = [1,2,3]
lr = 2
dir = 'result'

with open('readme.md', 'ab+') as f:
    f.write('## Layer sizes\n'.encode())

    for layer in layers:
        f.write(f'* {layer}\n'.encode())

    f.write(f'## Learning rate is {lr}\n'.encode())
    f.write('## Init\n'.encode())
    f.write('Add note about init\n'.encode())

md.markdownFromFile(input=open("readme.md", "rb"), output=open("out.html", "wb"))
