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
