法律研究Python Pandas - 获取周期所在月份的天数
要获取周期所在的月份中的天数，请使用 period.day 属性。
首先，导入所需的库 -
import pandas as pd
pandas.Period 表示一段时间。创建两个周期对象 -
period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4, minute = 55)从两个周期对象获取当月的天数 -
res1 = period1.day res2 = period2.day
示例
以下为代码 -
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2021-09-18")
period2 = pd.Period(freq ='D', year = 2021, month = 9, day = 22, hour = 4, minute = 55)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the day of the month from two Period objects
res1 = period1.day
res2 = period2.day
# Return the day of the month from the two Period objects
print("\nDay of the month from the 1st Period object ...\n", res1)
print("\nDay of the month from the 2nd Period object...\n", res2)输出
将生成以下代码 -
Period1... 2021-09-18 Period2... 2021-09-22 Day of the month from the 1st Period object ... 18 Day of the month from the 2nd Period object... 22
