法學研究Python Pandas——從 Period 物件中獲取年份
若要從 Period 物件獲取年份，請使用 period.year 屬性。首先，匯入所需的庫 −
import pandas as pd
pandas.Period 表示一個時間段。建立兩個 Period 物件
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)顯示 Period 物件
print("Period1...\n", period1)
print("Period2...\n", period2)從兩個 Period 物件獲取年份
res1 = period1.year res2 = period2.year
示例
以下為該程式碼
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 = 4, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the year from two Period objects
res1 = period1.year
res2 = period2.year
# Return the year from the two Period objects
print("\nDisplay the Year from the 1st Period object ...\n", res1)
print("\nDisplay 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... 2021-04-16 Display the Year from the 1st Period object ... 2020 Display the Year from the 2nd Period object... 2021
