如果我执行基本的 concat 函数,多索引会变成一堆元组,例如;
Food Clothes Bills Social
(2020-09-27 00:00:00, 2020-09-21 00:00:00) 25 25 25 25
etc.
有什么想法吗??对 pandas 还很陌生,而且编码一般,因此非常感谢任何帮助。
我更改了列标题以使其更易于使用。
周末 = Week_End
今天的日期 = Todays_Date
Daily_Total
您可以只附加行
df2 包含您的每周总计
#set an index to match your recorded spending df
df2['Week_End'] = '2020-09-27'
df2['Todays_Date'] = '0'
df2.set_index(['Week_End', 'Todays_Date'], inplace=True)
#append df2 to df
df = df.append(df2)
结果:
