Creating a loop with dynamic variables instead of hardcoded values

[FugaziRocks]

The first step is creating a dataframe of usernames and their corresponding User IDs. You also need to login to an Instagram account for authentication purposes.

1 2 3 4 5 6 7 8 9 10 11 12 13

from instagram_private_api import Client, ClientCompatPatch   from operator import itemgetter   import pandas as pd   import json   import requests     user_name = ''   password = ''   api = Client(user_name, password)     influencers = [['dcfoodcravings', '5577994064'], ['dcfoodlovers', '1902259438'], ['excellence.beauty.lounge', '2213626850'], ['foodzie', '1486757'], ['fiolamaredc', '1109579078']]     influencers_df = pd.DataFrame(influencers, columns=['username', 'userId'])

Once that's complete, we then move on to getting a list of their followers. This is where the issue is. You can see for the variables following_username, following_userid, and get_followers I am using **hard coded values.** But what I'm trying to do is run all the userId's (along with their corresponding username's in the influencers_df dataframe in a loop with dynamic variables.

So the end product would be list of all the followers from those username/userid combinations in the influencers_df dataframe.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

def followers_users(userid_instagram):        followers = []        combined = []        results = api.user_followers(userid_instagram, rank_token=api.generate_uuid())        followers.extend(results.get('users', []))        next_max_id = results.get('next_max_id')        while next_max_id:            results = api.user_followers(userid_instagram, rank_token=api.generate_uuid(), max_id=next_max_id)            followers.extend(results.get('users', []))            next_max_id = results.get('next_max_id')        userid = [followers[i]['pk'] for i in range(0,len(followers))]        full_names = [followers[i]['full_name'] for i in range(0,len(followers))]        usernames = [followers[i]['username'] for i in range(0,len(followers))]        profile_pic_url = [followers[i]['profile_pic_url'] for i in range(0,len(followers))]        followers_text = ['follower' for i in range(0,len(followers))]        following_username = ['dcfoodcravings' for i in range(0,len(followers))]        following_userid = ['5577994064' for i in range(0,len(followers))]        combined.extend([list(i) for i in zip(userid, full_names,                                                usernames, profile_pic_url, followers_text,                                                following_username, following_userid)])        combined = sorted(combined, key=itemgetter(2), reverse=False)        return(combined)    get_followers = followers_users('5577994064')    followers = pd.DataFrame(get_followers, columns = ['userID' , 'Full Name', 'username', 'Profile Picture', 'Type', 'following_username', 'following_userid'])    followers

If you don't know how to iterate over values in a dataframe series you should write a small program that focuses on doing that. Toe in, not jump in. Jump in is ok if you have a strong programming background with another language and all you are learning is syntax and libraries, but from your code example above I don't think you have that.

Okay, so how would you write the code I posted? I learn best by seeing what a final product would look like and then working backwards.

It is a style of Python coding that I've not come across before and must be a real mear to debug.

As an example, your code line...

1	followers_text = ['follower' for i in range(0,len(followers))]

... I would code as...

1 2	for i in range(len(followers)):     followers_text.append('follower')

... that said, I don't see that it's doing anything other than add the string 'follower' to the list object followers_text[] for as many times as there are item in the list object followers[].

Where did you learn this style?
