Python Pandas - 获取周期所在的星期几
pythonpandasserver side programmingprogramming
要获取周期所在的星期几，请使用 period.dayofweek 属性
首先，导入所需的库 −
import pandas as pd
pandas.Period 表示一段时间。创建两个 Period 对象 −
period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4,minute = 55)
显示 Period 对象 −
print("Period1...\n", period1)
print("Period2...\n", period2)
从两个 Period 对象中获取星期几 −
res1 = period1.dayofweek res2 = period2.dayofweek
示例
以下是代码 −
import pandas as pd
# pandas.Period 表示一段时间
# 创建两个 Period 对象
period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4,minute = 55)
# 显示 Period 对象
print("Period1...\n", period1)
print("Period2...\n", period2)
# 获取从两个 Period 对象中返回星期几
res1 = period1.dayofweek
res2 = period2.dayofweek
# 从两个 Period 对象中返回星期几
# 结果显示星期一=0，星期二=1，...，星期日=6
print("\nDay of the week from the 1st Period object ...\n", res1)
print("\nDay of the week from the 2nd Period object...\n", res2)
输出
这将产生以下代码 −
Period1... 2021-09-18 Period2... 2021-09-22
