Hi Michal!

When you work with Python interactively, the interpreter prints out
the results of expressions automatically. This doesn't happen when you
write a script, but it's often helpful with simple tinkering. The
numbers getting printed out are the returned values from the .write()
method; they're a simple check saying how much stuff got written. You
can ignore them - your file has been created correctly.
