step 1) Install unofficial sdk:
You can get facebook-sdk from here! 
Python Facebook-sdk: https://facebook-sdk.readthedocs.io/
Installing from Git
For the newest features, you should install the SDK directly from Git.Run the following command:
pip install -e git+https://github.com/mobolic/facebook-sdk.git#egg=facebook-sdk
step 2) Concepts:
       Facebook uses something called as graph which is a data structure used to model facebook's data where every person, comment , Post , Share everything we see is an object having its unique id and multiple connections to loads of other objects.
          This helps to model social connections like friendlist , hobbies, likes and shares . We can use this sdk in python to communicate to the graph api and carry out tasks needed. 
step 4) Access token generation:
        Facebook account authentication is done using unique access tokens.
 goto https://developers.facebook.com/ and login to your account click on tools and support 

step 3) Code:
This is an simple example of automatic liker
import facebook
import requests
if __name__ == '__main__':
    token = '***Paste Your Access Token Here***'
    graph = facebook.GraphAPI(token)
    profile = graph.get_object("me")
    feed = graph.get_connections(id="me", connection_name="home")
    toberemoved=[]
    posts=feed
    for i in range(4):
        try:
            # Perform some action on each post in the collection we receive from
            # Facebook.
            # Attempt to make a request to the next page of data, if it exists.
            posts = requests.get(posts['paging']['next']).json()
            feed['data'].extend(posts['data'])
        except KeyError:
            # When there are no more pages (['paging']['next']), break from the
            # loop and end the script.
            break
    print 'aquired {}'.format(len(feed['data']))    
    #:::::::::::::::like all the posts::::::::::
    for post in feed['data'] :
        graph.put_like(post['id'])
