Question on Loading a Jinja Template

  • 1.  Question on Loading a Jinja Template

    Posted 01-30-2022 07:24



    I have the following very basic Python script that uses a Jinja template file "scrap.j2" and instead of using a YAML file, I feed variables in the python script directly using a string.


    I am unable to successfully load the Jinja template. I get no error, but the result is an empty string.


    Here is my Python script

    #! /usr/bin/python3

    from jinja2 import Environment, FileSystemLoader


    #load Jinja Template


    my_template = env.get_template("scrap.j2")


    #feed variables to the template

    result = my_template.render({"user": "lab"})





    Here is my Jinja file scrap.j2

    hello {{ user }}




    I expect the script to print "hello lab", but instead it's printing an empty string.



    Kindly let me know what I'm doing wrong here.



    Many thanks,

    Hi Deepak,

    A quick copy/paste of your code with the associated jinja2 template works just fine for me.

    Maybe check versions of libraries, I was using Jinja2 3.0.1 and I also tested with 3.0.3 

    pip3 freeze | grep Jinja2

    hello lab
