Writing string representation of class instance to file

Question

I have defined the __str__ and __repr__ in my class foo
When I print foo(), it works just fine.
Of course, redefining stdout as a file object and calling print foo() would write the string representation to the file, but is that the most pythonic way to do it?

Answer 1

Simply call str or repr on the object, like this:

with open('somefile.txt', 'w') as f:
    f.write(repr(foo()))
