python - Variable set to call a function -

i hope question doesn't seem naive or silly, definite answer confirmation.

is possible set variable call function?

i.e

def func():     print "test"  var = [something magical + func] 

then if had typed/used var output test?

in other words, there alternate way calling function without use of parenthesis if never requires (or accepts) arguments [in python]?

i assuming isn't possible required use"()" call function, curious if there might exceptions?

in general, no. exception of properties mentioned in comments, need apply parameter list (even if it's empty ()) call function. otherwise, you're not calling function, referencing function value.

you can reproduce on python's command line interpreter:

>>> def func(): ...     return "foo" ...  >>> func() # call function; statement returns function's return value 'foo' >>> func # reference function value; statement returns *the function itself* <function func @ 0x7f2c7a65b938>  >>> var = func # assign function value variable >>> var # "var" references same function "func"... <function func @ 0x7f2c7a65b938> >>> var() # ...and can called function 'foo' >>>
