How to use the common interface to parse different file types

using_common_interface.py

import parse_file as dp

#define paths to test files
txt_path = 'test_txt.txt'
docx_path = 'test_docx.docx'
pdf_path = 'test_pdf.pdf'
html_path = 'test_html.html'
pptx_path = 'test_pptx.pptx'

file_paths = [txt_path,docx_path,pdf_path,html_path,pptx_path]

#instantiate a DocParser object
parser = dp.DocParser()

for path in file_paths:
    #call the parse method on each file path and print the result
    string = parser.parse(path)
    print(f'Parsing {path}:\n{string}\n')
