Try this:

from docx import Document
import re

document = Document(docx='existing.docx')
objective = "This is objective"

steps = ["step 1", "step 1.1", "step 1.2", "step 2", "step 2.1"]    

# read current document contents
for paragraph in document.paragraphs:

    if '[objective]' in paragraph.text:
        paragraph.text += objective

    for step in steps:
        indent = 1
        if re.search(r"{}\]".format(step), paragraph.text):
            print step, paragraph.text
            if '.' in step:
                indent += 1
            paragraph.text = '{}[{}]\t{}'.format('\t'*indent, step, step.title())
            steps.remove(step)

# add remaining steps not in existing document    
for step in steps:
    indent = 1
    if '.' in step:
        indent += 1
    document.add_paragraph('{}[{}]\t{}'.format('\t'*indent, step, step.title()))

document.save('output.docx')
