Just a side note for similar problem  If we don t want to loop through       How to lookup a dictionary using a variable key within Jinja template    Here is an example      set key   target db Schema upper        target db TableName upper         dict containing df get key  to html     safe      It might be obvious  But we don t need curly braces within curly braces  Straight python syntax works   I am posting because I was confusing to me      Alternatively  you can simply do    dict target db Schema upper        target db TableName upper     to html     safe      But it will spit an error when no key is found  So better to use get in Jinja
