Python 熊猫数据框:填充缺少的月份
我已经在Panda Timeseries上看到了这一点,但希望在数据帧方面得到一些帮助。我有一份1966-2009年的月度价值档案。我没有1985年的数据,也希望添加2010/2011年的数据。这些附加项只需附加NAN即可 使用下面的代码,我尝试剪切我的数据集,使其从1980年开始,然后添加缺少的年份,并附加NaN值。但是,没有任何内容被删除,也没有任何内容被添加。有什么我遗漏的吗Python 熊猫数据框:填充缺少的月份,python,datetime,pandas,time-series,Python,Datetime,Pandas,Time Series,我已经在Panda Timeseries上看到了这一点,但希望在数据帧方面得到一些帮助。我有一份1966-2009年的月度价值档案。我没有1985年的数据,也希望添加2010/2011年的数据。这些附加项只需附加NAN即可 使用下面的代码,我尝试剪切我的数据集,使其从1980年开始,然后添加缺少的年份,并附加NaN值。但是,没有任何内容被删除,也没有任何内容被添加。有什么我遗漏的吗 idx = pd.date_range('01-01-1980','12-31-2011',freq='M') y
idx = pd.date_range('01-01-1980','12-31-2011',freq='M')
years = np.arange(1980,2012,1)
obdata = pd.read_table('H:/Dissertation/Data/Observations/'+str(int(statid[e]))+'.txt',index_col='datetime',parse_dates={'datetime':[3,4]},date_parser=lambda x: pd.datetime.strptime(x, '%Y %m'),keep_date_col='True')
o_d = obdata.loc[obdata['Year'].isin(years)]
o_d['sd'] = np.nan_to_num(o_d['sd'])
o_d.reindex(idx,fill_value='NaN')
grouped_same.append(o_d['sd'])
现在提供了一些示例数据。如你所见,1985年缺失,数据在2009年停止。我将把所有的NaN转换为0,我想用'sd'作为NaN来填充丢失的月度数据

我认为更好的方法是使用
periodindex
将datetimeindex
转换为
您可以在列sd
中选择0
并与填充np.nan
一起使用
import pandas as pd
import numpy as np
obdata = pd.read_csv('H:/Dissertation/Data/Observations/'+str(int(statid[e]))+'.txt', index_col='datetime', parse_dates={'datetime':[3,4]},date_parser=lambda x: pd.datetime.strptime(x, '%Y %m'),keep_date_col='True')
#print obdata.head(100)
#convert string column Year to int (maybe you can omit it)
obdata['Year'] = obdata['Year'].astype(int)
#change datetimeindex to periodindex
idx = pd.date_range('01-01-1980','12-01-2011',freq='M').to_period('m')
years = np.arange(1980,2012,1)
#change datetimeindex to periodindex
obdata.index = obdata.index.to_period('m')
#fill NaN to 0 in column sd
obdata['sd'] = obdata['sd'].fillna(0)
o_d = obdata.loc[obdata['Year'].isin(years)]
#reindex and add NaN
o_d = o_d.reindex(idx,fill_value=np.nan)
请注意,pandas reindex没有在适当的位置运行,它返回一个新的数据帧,您没有保留它。您好,您是如何获得所有这些数据的?是否可以按照您创建数据时所说的方法进行修复?例如,如果数据是从一个程序生成的,那么是否可以更改该程序,以便您可以进行所有修复?此解决方案有效,但我的所有sd值都变为0,而不仅仅是我添加的新行。嗯,IIUC您需要转换为
0
仅从索引2009-02-28
到结尾的行?@jezreal还有一年(1985年)需要解决这一问题。我希望这些年是“NaN”或-999,最好是0可以是实际测量值。嗯,我不明白。重新索引后,您可以在数据样本前后得到NaN
。需要NaN
之前和样本0
之后?还是别的什么?或者在你的数据之间?在我有数据的地方,我有数字,有测量值,而NaN的测量值实际上为零。这就是为什么我使用行o_d=o_d.reindex(idx,fill_value=0)
将原始的nan转换为0
值。然后,对于我希望在数据集中插入缺失月份的位置(即1985年和2010/2011年),我希望['sd']
列中填入NaN
。
