Hello everyone

I want to slice a string on a flask template in python. Actually what I want to do is by using an if statement to make a link to something like "Read More" or just "..."

I tried the following in html and flask files respectively but it didn't work; any suggestions?

What I have tried:

{{ text|slice:":35" }} {% if text|length > 35 %}...{% endif %}

@app.route("/")
def index():
text= hhhhhhhhhjjjjjuuggghhjhhhhhhjjjjkkhhggdfffsashsjhdjjdk
return render_template("template.html", text=text)
