python: In this assignment, you will use a dictionary called balances to track money balances for people (think of it as a very insecure banking interface). This dictionary will be a global variable in your script. You will create two functions, depositMoney() and withdrawMoney(), that will be used to manipulate this dictionary to add or subtract money from a person's account. These functions will return a tuple of information. The functions you need to create are described in the function specifications below.

In this assignment, you will use a dictionary called balances to track money balances for people (think of it as a very insecure banking interface). This dictionary will be a global variable in your script.
You will create two functions, depositMoney() and withdrawMoney(), that will be used to manipulate this dictionary to add or subtract money from a person's account. These functions will return a tuple of information. The functions you need to create are described in the function specifications below.
Function 1: depositMoney(name, amount)
"""
Given a person's name and amount of money, adds amount to their account.
If person does not have an account, one is created for them.
Parameters:
name - string
amount - float, amount >= 0
Returns:
bool - True if account existed, False if account had to be created
float - new balance for person
"""
Function 2: withdrawMoney(name, amount)
"""
Given a person's name and amount of money, withdraws amount from their account.
If person does not have enough balance, function indicates overdraft
If person does not have an account, function indicates error
Parameters:
name - string
amount - float, amount >= 0
Returns:
bool - True if account existed, False if not
bool - False if existing account had enough balance for withdrawal, True if account went in to overdraft or didn't exist
float - New balance for person (or 0 if account did not exist)
"""
Before beginning your implementation, consider
- dict.keys()
- dict.get()
- dict.update()
- dict[keyValue]
Define the global dictionary balances and these functions in a file.
