从python中的日期中提取月份
问题描述：
我有一列日期格式为 2010-01-31.我可以使用
I have a column of dates in the format 2010-01-31. I can extract the year using
#extracting year
year = df["date"].values
year = [my_str.split("-")[0] for my_str in year]
df["year"] = year
我正在尝试获取月份，但我不明白如何在第二次拆分时获取它.
I'm trying to get the month, but I don't understand how to get it on the second split.
答
import datetime
a = '2010-01-31'
datee = datetime.datetime.strptime(a, "%Y-%m-%d")
datee.month
Out[9]: 1
datee.year
Out[10]: 2010
datee.day
Out[11]: 31
