You just use the variable fname instead of the function name!  For example:

>>> def myfun(x):
...  print "x is", x
...
>>> yourfun = myfun
>>> yourfun('This is cool')
x is This is cool

The "def" statement simply binds the function name to its compiled code
body.  If you "assign" the functin to another variable, the same call
mechanism can be used on that binding too.
