Jinja in Python: How to make IF statements work?

I am trying to automate some document generation with Jinja in a Python environment. I customised the jinja environment in order not to get conflicts with default character meanings in my IDE. The line_statement_prefix is set to #.

    latex_jinja_env = jinja2.Environment(
    block_start_string = '\BLOCK{',
    block_end_string = '}',
    variable_start_string = '\VAR{',
    variable_end_string = '}',
    comment_start_string = '%',
    comment_end_string = '}',
    line_statement_prefix = '#',
    line_comment_prefix = '%#',
    trim_blocks = True,
    autoescape = False,
    loader = jinja2.FileSystemLoader(os.path.abspath('.')))

I am trying to conditionally activate rows of a table, if a particular cell content is not 'nan'.

{# if \VAR{row['Climate (where PUE is located)']} not 'nan'}
{{Climate & \VAR{row['Climate (where PUE is located)']}\\}}
{# endif}

So far, any possible variation of the if statement did not yield the desired outcome. I'd be very grateful for any suggestions. Thank you.

Figured out that the content of \VAR cannot be accessed for evaluation, it is just possible to "print" it statically to the document that's being generated.

I solved the issue by generating a .tex document containing all vallues (including nan), then let a little script run over said .tex file in order to remove all rows with nan-value.
