Indeed. The first Python hit for me with that query was the tutorial page on I/O in Python 2, and it does exactly that. <http://docs.python.org/2/tutorial/inputoutput.html> That page does refer to the spec of the print statement, where you can find the way to redirect the output to a file, but you need to be able to read formal syntax specifications like this: print_stmt ::= "print" ([expression ("," expression)* [","]] | ">>" expression [("," expression)+ [","]]) The relevant pattern is the second alternative, after the vertical bar, which can be instantiated this way: print >> f, e0, e1 There is one object f with a .write method, and one or more expressions whose values get written using f.write; the effect of an optional comma at end is also specified there. Not tutorial-level. <http://docs.python.org/2/reference/simple_stmts.html#print> But I use the newer print function even if I have to use 2.7, something like this: from __future__ import print_function f = open("test.txt", "w") print("hello?", "see me?", file=f) f.close() It does a modest amount of formatting: the value of the keyword argument sep is written between the values, and the value of end is written at end. -- https://mail.python.org/mailman/listinfo/python-list
