Python Pandas - 返回前攝格里高利曆序數
若要返回前攝格里高利曆序數,請使用 timestamp.toordinal() 方法。首先,匯入所需的庫 −
import pandas as pd
在 Pandas 中建立時間戳物件
timestamp = pd.Timestamp(2021, 9, 18, 11, 50, 20, 33)
返回前攝格里高利曆序數。示例:年份 1 的 1 月 1 日是第 1 天
timestamp.toordinal()
示例
程式碼如下
import pandas as pd
# set the timestamp object in Pandas
timestamp = pd.Timestamp(2021, 9, 18, 11, 50, 20, 33)
# display the Timestamp
print("Timestamp...\n", timestamp)
# Return proleptic Gregorian ordinal.
# Example: January 1 of year 1 is day 1.
print("\nGregorian ordinal...\n", timestamp.toordinal())輸出
將會產生以下程式碼
Timestamp... 2021-09-18 11:50:20.000033 Gregorian ordinal... 738051
