Error debug, please help

class Account():

    def __init__(self,owner,balance):
        self.owner = owner
        self.balance = balance

    def deposit(self,amt):

        self.balance = self.balance + amt
        print(f"Your deposit of {amt} has been accepted! Your new account balance is: ${self.balance:1.2f}")

    def withdraw(self,amt):

        if self.balance:
            try:
                self.balance - amt

                if amt > self.balance:
                    print(f"You have insufficient funds for this request, please choose an amount of {self.balance:1.2f} or less")
                else:
                    print(f"Your request has been accepted. Your new account balance is {self.balance:1.2f - amt}")

        else:
            print("The account has a zero balance.")

For some reason, that last line "else: print("The account has a zero balance")" is giving me an error of: unexpected unindent. Although I think it is correct, I've still tried to align it differently, but to no avail. What are my tired eyes just not seeing?

You have a try block without an except block. You need both when you're using try/except for error handling.

Replace the last else with except, then indent it so it aligns with try.

@Wendy Leung, thanks to your comment, I was able to see that I was using "try" incorrectly-thank you also for the link so that I could refresh myself. Ultimately, I ended up rewriting & simplifying, which fixed the issue.

class Account():

    def __init__(self,owner,balance):
        self.owner = owner
        self.balance = balance

    def deposit(self,damt):

        self.balance = self.balance + damt
        print(f"Your deposit of {damt} has been accepted! Your new account balance is: ${self.balance:1.2f}")

    def withdraw(self,wamt):

        if self.balance >= wamt:
            self.balance -= wamt

            print(f"Your withdrawal of ${wamt} has been accepted. Your current balance is ${self.balance:1.2f}")

        else:
            print(f"You have insf funds to process this request. Please select an amount of ${self.balance:1.2f} or less.")

    def __str__(self):
        return f"This account belongs to {self.owner} and has an account balance of {self.balance}"

Try aligning the 2nd else statement with the first if statement, to me they don't look aligned
