Python Pandas - 格式化期间对象并以 24 小时格式显示时间
若要格式化期间对象,请使用 **period.strftime()** 方法,若要以 24 小时格式显示时间,请将参数设置为 %H.
首先,导入必需的库 −
import pandas as pd
pandas.Period 表示一段时间。创建期间对象
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)
显示期间对象
print("Period...\n", period)
显示结果。此处,时间以 24 小时格式显示,即 [00,23]
print("\nString representation (24-Hour format)...\n", period.strftime('%H'))
范例
以下是代码
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 = 17, minute = 20, second = 45) # display the Period object print("Period...\n", period) # display the result # Here, Time is displayed with 24-Hour format i.e. [00,23] print("\nString representation (24-Hour format)...\n", period.strftime('%H'))
输出
这将产生以下代码
Period... 2021-09-18 17:20:45 String representation (24-Hour format)... 17
