Python Pandas – 获取Period所在月份的总天数

要获取Period所在月份的总天数，请使用 period.daysinmonth 属性。

首先，导入所需的库−

import pandas as pd

pandas.Period表示一段时间。创建两个Period对象−

period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 2, day = 14, hour = 2, minute = 35)

显示Period对象−

print("Period1...\n", period1)
print("Period2...\n", period2)

获取两个Period对象所在月份的天数−

res1 = period1.daysinmonth
res2 = period2.daysinmonth

示例

以下是代码−

import pandas as pd

# pandas.Period表示一段时间
# 创建两个Period对象
period1 = pd.Period("2020-09-23")
period2 = pd.Period(freq="D", year = 2021, month = 2, day = 14, hour = 2, minute = 35)

# 显示Period对象
print("Period1...\n", period1)
print("Period2...\n", period2)

# 获取两个Period对象所在月份的天数
res1 = period1.daysinmonth
res2 = period2.daysinmonth

# 返回两个Period对象所在月份的天数
print("\nReturn Days in the month from the 1st Period object ...\n", res1)
print("\nReturn Days in the month from the 2nd Period object ...\n", res2)

输出

代码将输出以下结果−

Period1...
2020-09-23
Period2...
2021-02-14

Return Days in the month from the 1st Period object ...
30

Return Days in the month from the 2nd Period object ...
28
