I have a big html file named exercise.html, I need generate to one som stuff by Python CGI. I want to ask you what is the best way to print this HTML.
I know that it is possible by print method with using format methods %s, %i etc.:
print '''<html>
<head><title>My first Python CGI app</title></head>
<body>
<p>Hello, 'world'!</p>
.
.
<div>%s</div>
.
.
</body>
</html>''' % generated_text
But this HTML is really big,so is this only one solution?
You should consider using a templating language like Jinja2.
Here is a simple example straight from the link above:
>>> from jinja2 import Template
>>> template = Template('Hello {{ name }}!')
>>> template.render(name='John Doe')
Generally, though you save templates in a file, and then load / process them:
from jinja2 import Environment, PackageLoader
# The env object below finds templates that are lcated in the `templates`
# directory of your `yourapplication` package.
env = Environment(loader=PackageLoader('yourapplication', 'templates'))
template = env.get_template('mytemplate.html')
print template.render(the='variables', go='here')
As demonstrated above, templates let you put variables into the template. Placing text inside {{ }} makes it a template variable. When you render the template, pass in the variable value with a keyword argument. For instance, the template below has a name variable that we pass via template.render
This is my {{name}}.
template.render(name='Jaime')
Also consider Python Bottle (SimpleTemplate Engine). It is worth noting that bottle.py supports mako, jinja2 and cheetah templates.
The % indicates python code and the {{var}} are the substitution variables
HTML:
<ul>
% for item in basket:
<li>{{item}}</li>
% end
</ul>
Python:
with open('index.html', 'r') as htmlFile:
return bottle.template(htmlFile.read(), basket=['item1', 'item2'])
