Below is the code i'm using to make the claims for multiple accounts. It's by no means polished, but it's working right now, to claim and show some basic account stats. I adapted parts of the votebot code from felixxx (and winfrey) to do this as i'm hoping to join the two scripts together when I have time. Hope it helps.

PS the accounts have been imported (same as in piston) when running the script it asks for the wallet passphrase to make the transaction on each account. I haven't looked into setting the unlock variable yet

from steem import Steem

c = converter.Converter()


def claim():
    account = list_load('accounts.txt')
    posting_key = list_load('wif.txt')
    total_claimed = 0
    
    for (k,v) in enumerate(account):
            s = Steem(wif=posting_key[k])
            pre_account_info = s.get_account(v)
            rewards = float(pre_account_info['reward_vesting_steem'].split()[0])                        

            if rewards > 0:
                s.claim_reward_balance(account=v)
                status = 'Claimed Reward Balance of '
                total_claimed += rewards
            else:
                status = 'Nothing to claim '
                        
            post_account_info = s.get_account(v)
            follower_count = s.get_follow_count(v)
            vests = float(post_account_info['vesting_shares'].split()[0])
            steem_power = c.vests_to_sp(vests)
