Issue
In Flask there is the following code:
{% extends "base.html" %}
{% block content %}
<h1 class="title">
Welcome,{{ anyweirdname }}!
</h1>
{% endblock %}
You can render this HTML file using:
render_template('text.html', anyweirdname = "foo")
How can such syntatic sugar be implemented using Python? In other words, how can the computer know, that at {{ anyweirdname }} has to be replaced using anyweirdname = "foo"
Obviously this is not possible in languages like C, because C does not change its compilation by using another variable name. One would presume that the code used with other variable names – basically an isomorphism – would be indifferent, but it is obviously not.
Solution
If I understand you correctly, you are looking for a string where you can you can substitute variable names directly.
This can be done in Python 3.0+ using f-strings:
anyweirdname = 'foo'
print(f"Hello, {anyweirdname}")
Basically, you write f in front of the string where you want a variable substituted.
If this indeed is what you asked, you can find more information in this article.
