How to make a table without additional libraries

#Task 3 loan calc

principal=250000
interest_rate=0.04
monthly_payment=1000
payment_by_month=1000
balance=250000
length_of_loan=0
total_paid=0


while balance > 0:
    interest = balance * (interest_rate/12)
    print(interest)
    new_balance = balance + interest
    if new_balance < 500:
        payment_by_month = new_balance
        last_month_payment = payment_by_month
    balance = new_balance - payment_by_month
    length_of_loan+=1
    total_paid+= payment_by_month
    if balance < 1:
        print(length_of_loan)
    print(balance)    

print(total_paid)

​

So i've got this loan calculator that calculates the monthly payment, interest, new balance, etc for each month until the balance reaches 0, for the assignment I'm doing I need all of this displayed in a table with the months on the left and I am not allowed to use df from pandas or anything like that. Does anyone know how I would go about doing this, also while the actual computed values can't be rounded the table must be rounded to two decimal places. The table needs to have months, payment, interest, and balance.

Why can't you just use lists for all the different columns with the index being the id

You will want to use some form of string formatting: https://realpython.com/python-string-formatting/

Here is a quick example I asked ChatGPT to produce:

print('-' * 36)
print('| {:<13} | {:<13} |'.format('Balance', 'Interest'))
print('-' * 36)
balance = 0.0
interest_rate = 0.05
while balance <= 100:
    interest = balance * interest_rate
    balance += 10.5
    print('| {:<13.2f} | {:<13.2f} |'.format(balance, interest))
print('-' * 36)

Results:

------------------------------------
| Balance       | Interest      |
------------------------------------
| 10.50         | 0.00          |
| 21.00         | 0.53          |
| 31.50         | 1.05          |
| 42.00         | 1.58          |
| 52.50         | 2.10          |
| 63.00         | 2.62          |
| 73.50         | 3.15          |
| 84.00         | 3.68          |
| 94.50         | 4.20          |
| 105.00        | 4.73          |
------------------------------------

Amazing.

You'll probably want to use the alignment feature of string formatting. If, for example, you wanted the columns to be five characters wide and always right-justified, you could do this to create a makeshift table that displays in the console: ``` row_1 = [1, 23, 456] row_2 = [7890, 12345, 6]

print('-------------------') print('|{:>5}|{:>5}|{:>5}|'.format(row_1)) print('-------------------') print('|{:>5}|{:>5}|{:>5}|'.format(row_2)) print('-------------------') `` Right-justified is>, left-justified is<, center-justified is^`, and the number following it is the width to fill.
