program asking for the name and date (year, month and day) of a person’s birth in Python

Question

Hello, I am having difficulties in the following code in Python:.

The idea is to create a program that asks for the name and date (year, month and day) of birth of a person.

The program must also request the current date (year, month and day).

On the basis of these dates, it shall determine the age of the person.

Example of a result:

What’s your name? joaquin

What year were you born? 2001

What month were you born in? 2

What day were you born? 23

What year is it? 2018

What month is it? 4

What day is it? 9

Joaquim is 16 years old

The problem is that if a person turns his or her birthday on April 5, 1974 and the current date is January 2, 2018, that person should be 43 years old!

And this is where you’re always giving me 44 years! I don’t know if I made myself clear!??!

Here is my code

Answer 1

Right, you can create two date objects (dataNasc and dataAtual) and subtract to get the timedelta(difference between both) and after that consider the average of days of a year, getting more or less like this.

import datetime

#Entrada de valores
print('='*18)
print('Exercício 2: idade')
print('='*18)
nome = input ("Como se chama? ")
ano = eval (input ("Nasceu em que ano? "))
mes = eval (input ("Nasceu em que mês? "))
dia = eval (input ("Nasceu em que dia? "))
ano_atual = eval (input ("Ano atual? "))
mes_atual = eval (input ("Mês atual? "))
dia_atual = eval (input ("Dia atual? "))
dataNasc = datetime.date(ano, mes, dia)
dataAtual = datetime.date(ano_atual, mes_atual, dia_atual)

#diferença retorna em timedelta
diferenca = (dataAtual - dataNasc)
#Cálculos e Resultados
rslt = (diferenca.days / 365.25)
#ano_atual-ano

if (dia == dia_atual and mes == mes_atual):
    print ("O %s tem %d anos!" %(nome, rslt))
else:
    ((dia > dia_atual and mes == mes_atual) or mes < mes_atual)
    print ("O %s tem %d anos!" %(nome, rslt))
