Markup language is used to describe the visual appearance of a document to be displayed.
Browsers who deal with HTML do contain something similar to a interpreter(called parser).
Parser will identify various tags and display them accordingly - it depends on the way tags are rendered in browser.
One of the component in web browser is called rendering engine that performs this task.
Jinja2 is a template engine that generate HTML.
This mean that we can have Python code like eg a list and can make a loop in HTML that will render vaild HTML.
Server:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def index():
list_example = ['Python', 'HTML', 'CSS']
return render_template('index.html', list_example=list_example)
if __name__ == '__main__':
app.run(debug=True)Client in Browser:<!DOCTYPE html>
<html>
<head>
<title>Conditions</title>
</head>
<body>
<ul>
{% for name in list_example %}
<li>{{ name }}</li>
{% endfor %}
</ul>
</body>
</html>
