Issue

Like Python, you can access list elements by specifying their position. Can I do something similar with Flask

Example
main.py

definition line ():
list = [1,2,3,4,5]
return render_template('list.html',list=list)


list.html

{% for item in list %}
  
{{item}}
{% end for %}
 

As you know, the above line prints the entire list.
But can I print only the item of the list in the second position

Something like:

{% for item in list %}
      
{{item[2]}}
 {% end for %}
 

Display only:

3

 

Any ideas?? How to do it in flask using Jinja templates



Solution

here is your answer
<li>{{list[2]}}</li>

No need to print the whole list if you don’t want to, just pass the index.
