法律研究Python Pandas - 從 Period 物件中獲取一年中的某天
要從 Period 物件獲取一年中的某天，請使用 period.dayofyear 屬性。
首先，匯入所需的庫 -
import pandas as pd
pandas.Period 表示一段時間。建立兩個 Period 物件 -
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 7, day = 16, hour = 2, minute = 35)顯示 Period 物件 -
print("Period1...\n", period1)
print("Period2...\n", period2)從兩個 Period 物件獲取一年中的某天 -
res1 = period1.dayofyear res2 = period2.dayofyear
示例
以下是程式碼 -
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)輸出
這會生成以下程式碼 -
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
