I have a program that shows information about products and I wanted to present the date, but when the date appears, this is what it shows: PyQt5.QtCore.QDate(2018, 7, 7) .

For those who need this code here:

How to declare objective function in Python containing the same variable but for different intervals? Table with drag and drop event does not work on mobile

score 0 · Answer 1

Use toString() to display.

Ex :

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from PyQt5.QtCore import QDate

# Exibindo a data que foi passada para o QDate().
print(QDate(2018, 7, 7).toString())

The toString() also allows the formatting of the date, for this:

d : The days without zero (1 through 31).
dd : Days with zero (01 through 31).
ddd : Day name abbreviated (Ex: 'Seg', 'Dom').
dddd : Full day name (Ex: 'Monday' to 'Sunday').
M : The month without zero (1 through 12).
MM : The month with zero (01 through 12).
MMM : Abbreviated month name (Ex: 'Jan', 'Dec').
MMMM : Full month name (Ex: 'January', 'December').
yy : Year with 2 digits (00 through 99).
yyyy : Year with 4 digits.

Ex :

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from PyQt5.QtCore import QDate

# Formatando a exibição.
print(QDate(2018, 7, 7).toString('dd/MM/yyyy'))
print(QDate(2018, 7, 7).toString('ddd d MMMM yy'))
print('Hoje é:', QDate(2018, 7, 7).toString('dddd'))

Depending on the situation you can use:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from PyQt5.QtCore import QDate

# Formatadores prontos.
print('Dia:', QDate(2018, 7, 7).day())
print('Mês:', QDate(2018, 7, 7).month())
print('Ano:', QDate(2018, 7, 7).year())
