Here I want to show you how to generate an HTML file (a local file) using a template with theJinja2 template engine.
Python source (proba.py) #!/usr/bin/env python import os from jinja2 import Environment, FileSystemLoader PATH = os.path.dirname(os.path.abspath(__file__)) TEMPLATE_ENVIRONMENT = Environment( autoescape=False, loader=FileSystemLoader(os.path.join(PATH, 'templates')), trim_blocks=False) def render_template(template_filename, context): return TEMPLATE_ENVIRONMENT.get_template(template_filename).render(context) def create_index_html(): fname = "output.html" urls = ['http://example.com/1', 'http://example.com/2', 'http://example.com/3'] context = { 'urls': urls } # with open(fname, 'w') as f: html = render_template('index.html', context) f.write(html) def main(): create_index_html() ########################################
Jinja2 template (templates/index.html)
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>Proba</title> </head> <body> <center> <h1>Proba</h1> <p>{{ urls|length }} links</p> </center> <ol align="left"> {% set counter = 0 -%} {% for url in urls -%} <li><a href="{{ url }}">{{ url }}</a></li> {% set counter = counter + 1 -%} {% endfor -%} </ol> </body> </html>
Resulting output
If you execute proba.py, you will get this output:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>Proba</title> </head> <body> <center> <h1>Proba</h1> <p>3 links</p> </center> <ol align="left"> <li><a href="http://example.com/1">http://example.com/1</a></li> <li><a href="http://example.com/2">http://example.com/2</a></li> <li><a href="http://example.com/3">http://example.com/3</a></li> </ol> </body> </html>
