Pandas Python - 格式化和返回周期对象的字符串表示形式


要格式化和返回周期对象的字符串表示形式,请使用 period.strftime() 方法。然后,将格式说明符设置为参数,如 strftime('%d-%b-%Y')。

首先,导入所需的库 −

import pandas as pd

pandas.Period 表示一个时间段。创建 Period 对象

period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 8, minute = 20, second = 45)

显示 Period 对象

print("Period...\n", period)

显示格式化的字符串表示形式

print("\nString representation (format)...\n", period.strftime('%d-%b-%Y'))

示例

以下为代码

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 = 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'))

输出

这将产生以下代码

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
