Pandas Python - 格式化和返回週期物件的字串表示形式
要格式化和返回週期物件的字串表示形式,請使用 period.strftime() 方法。然後,將格式說明符設定為引數,如 strftime('%d-%b-%Y')。
首先,匯入所需的庫 −
import pandas as pd
pandas.Period 表示一個時間段。建立 Period 物件
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 8, minute = 20, second = 45)
顯示 Period 物件
print("Period...\n", period)顯示格式化的字串表示形式
print("\nString representation (format)...\n", period.strftime('%d-%b-%Y'))
示例
以下為程式碼
import pandas as pd
# The pandas.Period represents a period of time
# Creating a Period object
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 8, minute = 20, second = 45)
# display the Period object
print("Period...\n", period)
# display the result
print("\nString representation (format)...\n", period.strftime('%d-%b-%Y'))
# display the result
print("\nString representation (format with different directives)...\n",
period.strftime('%b. %d, %Y was a %A'))輸出
這將產生以下程式碼
Period... 2021-09-18 08:20:45 String representation (format)... 18-Sep-2021 String representation (format with different directives)... Sep. 18, 2021 was a Saturday
