Question

By using the following:

-Python(you can use the filter function)

-Data class

-Functional Programming(don't use while & for loops but you can use if statement)

Write a program that reads table with given columns from input stream. Columns are name, amount, debt.(ONLY 3 columns, the person's first name and surname is under the column 'name'). Then filter the table (condition: debt is equal to 0). After that increase debt by 14% then output the results.

-----------------------------------------

Example.

User's Input:

3 - No. of People

Sam Hill 411889 36881

Angela Smith 121877 0

Nicholas Ander 783887 591951

Expected Output:

Sam Hill  411889 52371.02
Nicholas Ander 783887 840570.42

-----------------------------------------------------

NOTE: Don't use dataframes(panda,etc) and the code should enable user to input their details.

HI,

Code is attached with Code Anippet.

Screenshot of the program to see the indentation and  output images are attached.

from dataclasses import dataclass

#program is developed with using for loop or while loop
#program is developed with using Python dataclass class Person


n = int(input("How many ppl data you want to enter?"))
i=0

personList = []

@dataclass
class Person:
    name: str
    amount: float
    debt: float

# this function taking multiple input from user based on number n and storing it in dataclass class Person class object
def iterate(num, start, end):
  person = []
  
  if start < 0  or start > end:
    
    return 
  print("Please enter "+str(start)+" record of person out of "+str(end))
  print("Please person name?")
  pn = input()
  print("Please amount?")
  pa = float(input())
  print("Please debt?")
  pd = float(input())
  
  pr = Person(pn,pa,pd)
  
  personList.append(pr)
  
  iterate(num, start + 1, end)

#iterate function to iterate list of Person dataclass and to display output which is required by you
def iterateDS(lst, start, end):
  personlst = []
  #print(end)
  if start < 0  or start > end:
      return 
    
  person = lst[start-1]
 
  if(person.debt!=0):
     
     per = (14/100)*person.debt
     
     person.debt = person.debt+per
     print(str(person.name)+"     "+str(person.amount)+"     "+str(person.debt)+"\n")
     
  iterateDS(lst, start + 1, end) 

# iterate to get input value from users with using for or while loop  
iterate(n, 1,n)
print("\nProgram Updated Output\n")
print("Name     Amount     Debt")
#iterate to list of dataset Personby without using for loop or while loop
iterateDS(personList, 1, len(personList))

#print(personList)
