I have visited these answers too Running Flask environment using HTML:receiving error message of expected else statement and How to fix jinja2 exceptions Template SyntaxError: but could not solve the problem.
I am a beginner at Flask and tried using jinja2 template inheritance. Here are my files.
index.html
{% extends "layout.html" %}
{% block body %}

I want to inheritent the template from layout.html to index.html. But I am getting this error:
jinja2.exceptions.TemplateSyntaxError: Unexpected end of template. Jinja was looking for the following tags: 'endblock'. The innermost block that needs to be closed is 'block'.
I have surfed a lot of websites to solve it but could not. Any help would be highly appreciated.
Finally! I just got the reason for the error. The error was generated at this line:
{% block body %} { % endblock % }
After figuring it out, I came to know that there should be no space between the braces and the %
sign. And the code should look like this.
{% block body %} {% endblock %}
