Input of 0 not working when converting to float?

I'm having a problem in the betting part of a blackjack game i am making, i would like the player to be able to bet $0 if they want to, however when you input 0 it simply repeats the input. Please help as this is the last step to a successful game that i have been working on for a while.

money=250
validbet=False
while validbet==False:
    bet = None
    while not bet:
        unchecked_bet = input("How much would you like to bet? $")
        try:
            bet = float(unchecked_bet)
        except ValueError:
            print("Sorry, that is not a valid bet. Please enter a valid bet.".format(unchecked_bet))

    bet=float(unchecked_bet)

    if bet>=0 and bet<=money:
        validbet=True
    else:
        print("Sorry, that is not a valid bet. Please enter a valid bet.")
        validbet=False


print("You have bet: $"+str(bet))

Thanks in advance

while not bet

evaluates to False if bet == 0. You probably want to check for

while bet is None

to handle None more explicitly.

Note that bet == None would work as well. But bet is None is more precise and the recommended way to check for None. (See this question for more details.)
