Python 3.5:

Consider the Account class that we developed previously.

Task 1:

Review the code in the constructor in the Account class. What happens if we attempt to make a new account with a negative balance? Use exception handling to raise an exception if a balance less that 0 is given. Add a message to the constructor saying "Warning! Your balance is equal to or less than 0!".

Task 2:

Next, in the Account class's withdraw() method, add code to check if the amount given exceeds the account's balance. If it does, then raise a ValueError. Add a message to the withdraw() method saying "ERROR: Insufficient funds!". The balance in the account should remain unchanged.

Also, add code to check if the amount of withdrawal is zero. You should raise a ValueError if the amount is less than or equal to zero.

Note: you must submit the entire class definition.

For example:

Test	Output
try: account1 = Account(1122, 0, 3.35) except ValueError as x: print (x)	Warning! Your balance is equal to or less than 0.
try: account2 = Account(1122, 100, 3.35) account2.withdraw(200) except ValueError as x: print (x) print(account2.get_balance())	ERROR: Insufficient funds! 100
try: account2 = Account(1122, 100, 3.35) account2.withdraw(0) except ValueError as x: print (x) print(account2.get_balance())	ERROR: Invalid amount! 100

Account Code:
