[英]groupby datetime year-month only
I need to groupby based on the year & month of the Date column so I have a clearer graph presentation and less sample-size.我需要根据 Date 列的年份和月份进行分组,这样我的图形表示更清晰,样本量更少。
df.groupby(df2['Date'])['¢/kWh'].mean()
This has helped me to have less sample size and a better presentation.这帮助我减少了样本量和更好的演示。 However I need to further groupby based on the month and year.但是我需要根据月份和年份进一步分组。
Try:尝试:
df.groupby(df2['Date'].astype(str).str[0:7])['¢/kWh'].mean()
