[Tutor] How to print to a file?

[denny]

I want to write something to a file like this:
print >>filehandle, "....%d...%s..."%(num,string)
but it raise error

Can someone tell me how can I print it above to a file just like
we print to the stdout(print "....%d...%s..."(num,string)).
Or is there some funtion as we use in C/C++( fprint etc)

thanks
