Python 如何识别元组中相同的元素

我有一个具有以下结构的元组

#list of tuples
[('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))]
#[0] index position
('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))

现在，如何识别

datetime.datetime（2020,5,11,11,31,0160000）

和

datetime.datetime（2020,5,11,12,8,25320000）

是否相同（相等性测试）

我已经回答了这个问题

关于

日期时间

支持相等性测试

a = [('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))]
print(a[0][0] == a[0][1])  # False

---

Datetime

支持相等性测试

a = [('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))]
print(a[0][0] == a[0][1])  # False

下面的代码用于识别相同的元组索引项

       #list of tuples
        row = [('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))]   


        #converting list to a tuple
        listT = row[0]
        listT = ('Persons', datetime.datetime(2020, 5, 11, 11, 31, 0, 160000), datetime.datetime(2020, 5, 11, 12, 8, 25, 320000))

        #comparing tuple index positions
        if listT[1] == listT[2]:
            print('both are equal')
        else:
            print('they are not equal')

这回答了你的问题吗？这回答了你的问题吗？嗨@Will Derriman…即使是相等的元素也显示为false。例如，

[（'brand_approvals'，datetime.datetime（2020,5,6,18,5,9,600000），datetime.datetime（2020,5,6,18,5,9,600000））]显示为false

。谢谢你的回答：）嗨，克里斯特，很有趣

dt1=datetime.datetime（2020,5,11,11,31,0,160000）dt3=datetime.datetime（2020,5,11,11,31,0,160000）dt2=datetime.datetime（2020,5,11,12,8,25320000）print（dt1==dt2）#False print（dt1==dt3）#True
