I am new to Python. I am learning through this 100 days video tutorial from Udemy. However surprisingly same code worked for the tutor on video but not for me. After going through current posts with similar error I couldn't figure out the solution and decided to post my question. I have checked in Thonny debugger an code- bid_amnt = bidding_record[bidder] is where value comes with the coma at the end. I have tried converting it to integer by int(bidding_record[bidder]) also but it didn't work. Please tell me how to correct.

#Code snippet
def find_highest_bidder(bidding_record):
    #bidding_record = {Angela:123, James:321} examlpe of dictionary prepared
    highest_bid = 0
    winner = ""
    for bidder in bidding_record:   
        bid_amnt = bidding_record[bidder]
        if bid_amnt > highest_bid:
            highest_bid = bid_amnt
            winner = bidder
  print(f"Winner of this bid is {winner} with ${highest_bid}")

#Declaring variable for loop and empty dictionary
bid_on = True

while bid_on == True:
    #Taking user Inputs
    name = input("Please enter your name: \n")
    bid_value = int(input("please enter your bid amount: $"))
    other_users = input("are there other users who want to bid type yes/no:  \n").lower() 
    bid_dict[name] = bid_value,
  
    #Calling function by passing dictionary in argument  
    find_highest_bidder(bid_dict)
  
    #Calling clear function from replit if there are no more users  
    if other_users == "no":
        bid_on = False
    else:
    clear()

CodePudding user response：

I see what happened. In the line bid_dict[name] = bid_value, you are defining bid_dict[name] to be a tuple since bid_value has a , after it.

In python, whenever you put a comma after a variable like this, it expects it to be a tuple and converts it to that datatype.

Then in the line if bid_amnt > highest_bid: it is trying to compare bid_amnt which is the tuple you defined above with bid_value, to the int you defined as highest_bid = 0

Remove that comma and it should work.
