I'm trying to make a pension tax calculator and have created a class "Client" that will accept inputs from two separate users and calculate their taxes based on these inputs.
Is there a cleaner way for me iterate through each client than to repeat this code?
client1 = Client.from_input()
print(client1.name, 'Maximum pension contribution you can make this tax year: ', client1.get_maximum_contribution())
print(client1.name, 'Maximum pension contribution your employer can make this year: ', client1.get_carryforward() + client1.get_remaining_aa())
print(client1.name, 'Remaining annual allowance: ', client1.get_remaining_aa())
print(client1.name, 'Carryforward available: ', client1.get_carryforward())
client2 = Client.from_input()
print(client2.name, 'Maximum pension contribution you can make this tax year: ', client2.get_maximum_contribution())
print(client2.name, 'Maximum pension contribution your employer can make this year: ', client2.get_carryforward() + client1.get_remaining_aa())
print(client2.name, 'Remaining annual allowance: ', client2.get_remaining_aa())
print(client2.name, 'Carryforward available: ', client2.get_carryforward())
If anybody wants the full code or if it's relevant:
```# import datetime
# currentyear = datetime.date.today().year
# year3 = (datetime.date.today().year - 3)
# year2 = datetime.date.today().year - 2
# year1 = datetime.date.today().year - 1

Yes, you can add a __str__ method to your Client-class to define how the string-representation of your objects should look like. E.g.:
import os
...
class Client:
...
def __str__(self):
line1 = f"{self.name} Maximum pension contribution you can make this tax year: {self.get_maximum_contribution()}"
line2 = f"{self.name} Maximum pension contribution your employer can make this year: {self.get_carryforward() + self.get_remaining_aa()}"
line3 = f"{self.name} Remaining annual allowance: {self.get_remaining_aa()}"
line4 = f"{self.name} Carryforward available: {self.get_carryforward()}"
return os.linesep.join([line1,line2,line3,line4])
If you do that you can just do print(client1) in your code.
Alternatively, you can just name this method getstring and do it like this print(client1.getstring()).
If you want to iterate though your clients you can do it like this:
client_list = [Client.from_input() for _ in range(num_clients)]
for client in client_list:
print(client)
To create a list of num_clients with your from_input method and print them all out.
