list2=['PewDiePie', 'jacksepticeye', 'iDubbbzTV', 'Markiplier','MarkiplierGAME',  'EminemMusic','EdSheeran', 'TaylorSwift', 'CNN', 'FoxNews', 'CBCNews', 'ABCNews', 'NBCNews', 'SkyNews', 'ESPN', 'UFC', 'BellatorMMA', 'NBA', 'KhanAcademy', 'Sentdex', 'CrashCourse', 'BigThink', 'DoctorMike']

from googleapiclient.discovery import build
import pandas as pd
df=pd.DataFrame()
for i in range(len(list2)):
   request= youtube.channels().list(part='snippet',forUsername=list2[i])
   response= request.execute()
   print(response['items'][0]['snippet']['description'])#channel description
   channel_description= response['items'][0]['snippet']['description']
   request= youtube.channels().list(part='contentDetails',forUsername=list2[i])
   response= request.execute()
   print(response['items'][0]['contentDetails']['relatedPlaylists']['uploads'])#upload_code
   upload_code = response['items'][0]['contentDetails']['relatedPlaylists']['uploads']
   request= youtube.playlistItems().list(part ='snippet',playlistId=upload_code ,maxResults=5) #retrieving videos
   response= request.execute()
   print(response['items'][0]['snippet']['description'])
   print(response['items'][0]['snippet']['title'])
   dfdict={
    "channel_title": list2[i],
    "channel_description": channel_description,
    "vid1_title":response['items'][0]['snippet']['title'],
    "vid1_description":response['items'][0]['snippet']['description'],

}
   df = df.assign(**dfdict)

print('/////////////////////////////////////')

df

I am trying to populate the dataframe "df" with the channel name, channel description, title and description of the first video pulled. so far with this method i have had no luck as it simply returns an empty dataframe. in the code i store the data in the dictionary "dfdict" then attempt to use the assign command to store it in the df.
