Creating a loop with dynamic variables instead of hardcoded values - FugaziRocks - Jul-27-2022
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.
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. 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...
followers_text = ['follower' for i in range(0,len(followers))]... I would code as...
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?
