Hello I am having trouble completing this python
assignment. I keep getting the error message list index out of
range. how do i fix it instruction and code
below.
code:
# Main function
def main():
# User input filename
fname = input("Enter text file name: ")
# Function call to get data from text file
data = ReadFile(fname)
# Loop
while True:
# Function call ro print menu
and get option
option = Menu()

# If user chose option 1 then
printing balance
if option == 1:

CheckBalance(data['Balance'])

# If user chose option 2 then
adding income
elif option == 2:
income =
AddIncome(data)

data['Balance'] += income

# If user chose option 3 then
adding expense
elif option == 3:
expense =
AddExpense(data)

data['Balance'] -= expense

# If user chose option 4 then
printing monthly total
elif option == 4:

MonthlyTotal(data)

# If user chose option 5 then
printing monthly statement
elif option == 5:

PrintStatement(data)

# If user choce option 6 the
writing monthly statement to
# a file
elif option == 6:

StatementToFile(data)

# If user chose option 7 then
changing name of customer, changing
# month, and clearing
expense/income data. Finally writing data to
# file and breaking the
loop
elif option == 7:

data['Name'] = ChangeName()
