I have a function that looks for the largest number in a dictionary nested in a list. However, I need help understanding it. Th

highest_bid = 0 ##  assuming bids are greater than 0, this is a good initialization value
winner = None   ## another sensible initialization value
for bidder in bid_log: ## this is a loop over the items of the list, every item is a dictionary, e.g. { "Name" : "Bob", "bid" : 100 }

  bid_amount = bidder["bid"]  ## retrieve the bid from the current dictionary

  if bid_amount > highest_bid: ## if the bid is greater than the (current) maximum then...
    highest_bid = bid_amount  ## update the current maximum bid value
    winner = bidder ## keep track of the relative bidder

print(f"The winner is {winner['name']}") ## eventually output the result
