print adds a single space after every argument, including `\n'. You might want to combine the three strings into a single argument yourself.
print(my_var1 + '\n' + my_var2)
or
print('\n'.join([my_var1, my_var2]))
Better than either of these would be to use the format string method:
print('{}\n{}'.format(my_var1, my_var2))
which both handles conversion to str if necessary and eliminates any temporary objects.
