I didn't know that printing to a file with print() was possible, so I tried
>>> print("Hello, world!", file="C:\test\test.txt")
Traceback (most recent call last):
File "<string>", line 1, in <fragment>
builtins.AttributeError: 'str' object has no attribute 'write'
>>>
And the docs at
<http://docs.python.org/py3k/library/functions.html#print> tell me
"The file argument must be an object with a write(string) method; if
it is not present or None, sys.stdout will be used."
What do I do to test.txt to make it "an object with a write(string) method"?
Thanks,
