python - How to check instanceof in mako template? -

i have variable myvariable want use in mako template. want able somehow check type before doing it. syntax check sort of information? know python has typeof , instanceof, there equivalent in mako or how it?

pseudocode below:

% if myvariable == 'list': // iterate throuh list    %for item in myvariable:          ${myvariable[item]}    %endfor %elif variabletype == 'int': // ${myvariable}  %elif myvariable == 'dict': // here 

you can use isinstance():

>>> mako.template import template >>> print template("${isinstance(a, int)}").render(a=1) true >>> print template("${isinstance(a, list)}").render(a=[1,2,3,4]) true 

upd. here's usage inside if/else/endif:

from mako.template import template t = template(""" % if isinstance(a, int):     i'm int % else:     i'm list % endif """)   print t.render(a=1)  # prints "i'm int" print t.render(a=[1,2,3,4])  # prints "i'm list"
