Split a string into a list in Jinja

I have some variables in a Jinja 2 template which are strings separated by a ';'. I need to use these strings separately in the code. I.e., the variable is variable1 = "green;blue" {% list1 = {{ variable1 }}.split(';') %} The grass is {{ list1[0] }} and the boat is {{ list1[1] }} I can split them up before rendering the template, but since it is sometimes up to 10 strings inside the string, this gets messy. I had a JSP part before where I did: <% String[] list1 = val.get("variable1").split(";");%> The grass is <%= list1[0] %> and the boat is <%= list1[1] %> It works with: {% set list1 = variable1.split(';') %} The grass is {{ list1[0] }} and the boat is {{ list1[1] }}
A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment). I haven't found this function in the official documentation, but it works similar to normal Python. The items can be called via an index, used in a loop or, like Dave suggested, if you know the values, it can set variables like a tuple. {% set list1 = variable1.split(';') %} The grass is {{ list1[0] }} and the boat is {{ list1[1] }} or {% set list1 = variable1.split(';') %} {% for item in list1 %} <p>{{ item }}<p/> {% endfor %} or {% set item1, item2 = variable1.split(';') %} The grass is {{ item1 }} and the boat is {{ item2 }} (This is after coming back to my own question after 5 years and seeing so many people found this useful, a little update.)
