法律研究Python Pandas - 从 Period 对象中获取一年中的某天
要从 Period 对象获取一年中的某天，请使用 period.dayofyear 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("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 7, day = 16, hour = 2, minute = 35)显示 Period 对象 -
print("Period1...\n", period1)
print("Period2...\n", period2)从两个 Period 对象获取一年中的某天 -
res1 = period1.dayofyear res2 = period2.dayofyear
示例
以下是代码 -
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 7, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the day of the year from two Period objects
res1 = period1.dayofyear
res2 = period2.dayofyear
# Return the day of the year from the two Period objects
# The return value ranges between 1 to 365 for regular years and 1 to 366 for leap years
print("\nDay of the year from the 1st Period object ...\n", res1)
print("\nDay of the year from the 2nd Period object...\n", res2)输出
这会生成以下代码 -
Period1... 2020-09-23 Period2... 2021-07-16 Day of the year from the 1st Period object ... 267 Day of the year from the 2nd Period object... 197
