evaluate a string as method in a python for loop

Question

Eventually I will be using python datetime methods such as day, month and year.

I can easily assign them manually:

import datetime as dt

year = dt.datetime.today().year
month = dt.datetime.today().month
day = dt.datetime.today().day

But as I need to further manipulate them (e.g. transform to str, I guess it is better to do variable assignment inside a loop)

What I have tried so far, and the error messages are displayed below (I have tried one x variable assignment at the time i.e. when I tried one variable assignment, the other attempts were commented)

import datetime as dt

today = dt.datetime.today()
for i in 'year month day'.split():
    x = today.i # AttributeError: 'datetime.datetime' object has no attribute 'i'
    x = f"{today}.{i}" # does not return an error, but returns '2023-01-04 12:06:45.614862.day'
    x = today.eval(i) # AttributeError: 'datetime.datetime' object has no attribute 'eval'
    x = eval(today.i) # AttributeError: 'datetime.datetime' object has no attribute 'i'

So in a nutshell, what I want in my loop is that python transforms the i strings (year, month and day) and use that as a method for today()
