Python循环添加随机日期到列表

Question

我有一份3份清单，按日期逐日打印， 例如： xlist 叶利斯特 xlist xlist 叶利斯特等

以下是我当前的脚本：

import datetime as dt
import pandas as pd

start_date = dt.datetime(2019, 4,12)
end_date = dt.datetime(2019, 4,21)
daterange = pd.date_range(start_date, end_date)

XLIST = ['401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
YLIST = ['201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
ZLIST = ['301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']

i = 0
for date in daterange:
    if i % 3 == 0:
        print(XLIST)
    elif i % 3 == 1:
        print(YLIST)
    else:
        print(ZLIST)
    i+=1

以上脚本输出为：

['401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
['201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
['301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
['401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
['201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
['301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
['401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
['201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
['301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
['401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']

我对输出不满意：

我需要日期也应该在列表中：

以下是我的预期输出：

[12/04/2019, '401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
[13/04/2019, '201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
[14/04/2019, '301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
[15,04/2019,'401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
[16/04/2019, '201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
[17/04/2019, '301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
[18/04/2019, '401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']
[19/04/2019, '201', 'Donald Ted', '202', 'Einastain', '203', 'Hillary Cloud']
[20/04/2019, '301', 'Theresa March', '302', 'Jullian Ass Bad', '303', 'Messi Bro']
[21/04/2019, '401', 'Pabolo Picasso', '402', 'Justin TED', '303', 'Ariana Great']

Guide：如果您看到脚本和预期的输出，那么您将不会看到我正在查看的内容和我停止的位置。 非常感谢

在循环中创建新列表，以便不修改原始列表：

for date in daterange:
    if i % 3 == 0:
        print([str(date)] + XLIST)
    elif i % 3 == 1:
        print([str(date)] + YLIST)
    else:
        print([str(date)] + ZLIST)
    i+=1

您可能希望格式化日期，而不是只调用str。 不管怎样，这里有live example
