for-in-if in jinja2 throws exception
Question: I am new to both Python and Jinja2. I'd like to read a value in a dictionary
of a list. I think there is an answer for such operation
[here](http://stackoverflow.com/a/8653568/124050). Unfortunately this does not
seem to work in Jinja2. I get this:

> jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'item'.

From what I know Jinja2 does not comprehend full Python, which I think is at
the heart of the problem here. Can anyone please confirm?


Answer: Example using Flask:

main.py

    
    
    from flask import Flask, render_template
    
    app = Flask(__name__)
    
    @app.route('/')
    def hello_world():
        dicts = [
            { "name": "Tom", "age": 10 },
            { "name": "Mark", "age": 5 },
            { "name": "Pam", "age": 7 },
            { "name": "Dick", "age": 12 }
        ]
        return render_template("test.html", dicts = dicts)
    
    if __name__ == '__main__':
        app.run(debug = True)
    

In folder templates

test.html

    
    
    <html>
    <head>
    <table>
       <tr>
        <th>Name</th>
        <th>Age</th>
       </tr>
    {% for dic in dicts %}
        {%if dic['name'] == 'Pam'%}
            <tr><td><b>{{dic['name']}}</b></td><td><b>{{dic['age']}}</b></td></tr>
        {%else%}
            <tr><td>{{dic['name']}}</td><td>{{dic['age']}}</td></tr>
        {%endif%}
    {% endfor %}
    </table>
    </body>
    </html>
    

Output:
