Basically, if module foo.bar contains an `import baz` with relative imports
python will look for foo.baz before searching for baz in sys.path; with
absolute imports `from . import baz` will only look for baz in the current
package while `import baz` will only search sys.path.

1 directory, 4 files
$ cat baz.py
print("import is absolute")
$ cat foo/baz.py
print("import is relative")
$ cat foo/bar.py
$ python -c 'import foo.bar'
import is relative
$ python3 -c 'import foo.bar'
import is absolute
