How to convert string to uppercase / lowercase in Jinja2?

I am trying to convert to upper case a string in a Jinja template I am working on. In the template documentation, I read: upper(s) Convert a value to uppercase. So I wrote this code: {% if student.department == "Academy" %} Academy {% elif upper(student.department) != "MATHS DEPARTMENT" %} Maths department {% endif %} But I am getting this error: UndefinedError: 'upper' is undefined So, how do you convert a string to uppercase in Jinja2?
Filters are used with the |filter syntax: {% elif student.department|upper != "MATHS DEPARTMENT" %} Maths department {% endif %} or you can use the str.upper() method: {% elif student.department.upper() != "MATHS DEPARTMENT" %} Maths department {% endif %} Jinja syntax is Python-like, not actual Python.
