Python. How read gdoc like I read docx on synchronized gdrive ?

[CommeUnChat]

Hello.

I'm able to read any docx synchronized with my google drive.
But not gdoc.

I tried : 

pip install gdoc
import gdoc
text_ori = gdoc.Document(FILE_PATH)

It return me :

AttributeError: module 'gdoc' has no attribute 'Document'

I'm really bad dev.
I need your help.
