I am getting a conditions not defined message on my code.

name = input("Enter your name or 'q' to quit:")

while name != "q":

accountbalance = float(input("Enter an amount your account balance:S"))

amount = float(input("Enter amount to withdraw (-) or deposit (+):S"))

if condition:

(amount > 0)

newAccountBalance = accountBalance + abs(amount)

else:

newAccountBalance = accountBalance - abs(amount)

if newAccountBalance == 0:

print("Your account balance is zero")

elif newAccountBalance < 0:

print(

"Your Account is overdrawn. The overdrawn account is S"

+ str(round(newAccountBalance, 2))

)

name = input("Enter your name or 'q' to quit")

print(" Exiting Program")
