本篇实现的作用是利用<a href="http://jinja.pocoo.org/docs/" target="_blank" rel="noopener">Jinja2</a>模板根据需要生成html 页面。
ghtml.py内容如下:
<br />
# cat ghtml.py
#!/usr/bin/env python
# coding=utf-8
# code from www.361way.com
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 = ['https://www.361way.com/tag/python', 'https://www.361way.com/tag/linux', 'https://www.361way.com/tag/mysql']
context = {
'urls': urls
}
#
with open(fname, 'w') as f:
html = render_template('index.html', context)
f.write(html)
def main():
create_index_html()
########################################
if __name__ == "__main__":
main()
templates/index.html模板内容如下:
<br />
# cat templates/index.html
generating html
generating html
{{ urls|length }} links
{% for url in urls -%}
- {{ url }}
{% endfor -%}
执行后生成的内容如下:
<br />
# cat output.html
generating html
generating html
3 links
