Function to get Spotify access token

access_token_spotify.py

def accesstoken(client_id, client_secret):
    header_string= base64_encode(client_id,client_secret)
    headers = {
        'Authorization': 'Basic '+header_string,
    }
    
    data = {
        'grant_type': 'client_credentials'
    }
    
    response = requests.post('https://accounts.spotify.com/api/token', headers=headers, data=data)
    access_token = json.loads(response.text)
    access_token = access_token['access_token']
    return(access_token)

access_token = accesstoken('your Client ID','your Client Secret')
access_token

"""

Sample response is

{'access_token': 'BQA5Zu1uNhJbKpr3tBcWRseAy-qfwwPXMjJQEvXyqKdy0Y1XaQvsC8HTE7qYuI1e_fMUVuwLltADeA-QuNc', 'token_type': 'Bearer', 'expires_in': 3600, 'scope': ''}

And using this function you don't need to worry about extracting the access_token from the JSON response.
The accesstoken function will return a string like this

'BQA5Zu1uNhJbKpr3tBcWRseAy-qfwwPXMjJQEvXyqKdy0Y1XaQvsC8HTE7qYuI1e_fMUVuwLltADeA-QuNc'
