Relative imports

[Chris]

After reading that link I tried to change my imports like this:
" from .myPythonFileInTheSameFolder import MyClass"

Well, this caused an error in PyLint:
Encountered "." at line 1, column 6. Was expecting one of:     "or" ...
    "and" ...     "not" ...     "is" ...     "in" ...     "lambda" ...
   "if" ...     "else" ...     "elif" ...     "while" ...     "for" ...
    "try" ...     "except" ...     "def" ...     "class" ...
"finally" ...     "print" ...     "pass" ...     "break" ...
"continue" ...     "return" ...     "yield" ...     "import" ...
"from" ...     "del" ...     "raise" ...     "global" ...     "exec"
...     "assert" ...     "as" ...     <NAME> ...
ID:E0001  invalid syntax

I'm getting more and more confused...
How can I correctly do a relative import ?
