PANDAS dataframe concat and pivot data

Asked 2021-May-24 at 21:16

I'm leaning python pandas and playing with some example data. I have a CSV file of a dataset with net worth by percentile of US population by quarter of year. I've successfully subseted the data by percentile to create three scatter plots of net worth by year, one plot for each of three population sections. However, I'm trying to combine those three plots to one data frame so I can combine the lines on a single plot figure.

Data here: https://www.federalreserve.gov/releases/z1/dataviz/download/dfa-income-levels.csv

Code thus far:

I don't see the categories mentioned in your code in the csv file you shared. In order to concat dataframes along columns, you could use pd.concat along axis=1. It concats the columns of same index number. So first set the Date column as index and then concat them, and then again bring back Date as a dataframe column.

To set Date column as index of dataframe, df1 = df1.set_index('Date') and df2 = df2.set_index('Date')
Concat the dataframes df1 and df2 using df_merge = pd.concat([df1,df2],axis=1) or df_merge = pd.merge(df1,df2,on='Date')
bringing back Date into column by df_merge = df_merge.reset_index()

QUESTION

Select x records after the minimum and max value within factor group(s)

Asked 2020-Jul-21 at 13:30

I have a dataset of daily temperature from different locations and different years. I would like to select the minimum value and then the records 90 days after this value for each location within each year. I would also like to selected the maximum value and the the records 90 days after this. I apologise, but I am not really sure how to easily provide a reproducible example given the cyclical nature of the data.

As an example, with the following data if I want to extract the rows from 3 days after the lowest and highest temp from each year:

Here's a tidyverse solution. In the absence of reproducible data, I have made some up that follow a cyclical pattern over a 3-year period:

Filtering a dataframe column for rows that contain certain text

Asked 2019-May-09 at 15:46

The str.contains method is a vectorized string operation ( see here). This means that it is a method for for pandas Series and not string types. When you use df.apply, pandas tries to use str.contains for each element of the column you selected instead of doing it at the Series level.

I would suggest the following approach:

Spring Integration TCP - What is a good way to close listening socket completely

Asked 2018-Aug-13 at 15:17

Is it a good option to use

AbstractServerConnectionFactory.closeCOnnection(ClientConnId). I am using this but what happens is that after a few days of processing server starts giving "too many open files" error. I investigated that Issue by running the commands "lsof" AND "/proc/pid/fd" that showed me around 280 file descriptors for the sockets and pipes

Closing the socket using it's ID should close it completely.

However, simply set the soTimeout property and the operating system will notify the framework, which will close the socket if no data is received in that time.

throw new SoftEndOfStreamException

I am not sure where you are doing that, but I can't think of a scenario where it would close the server socket.

That exception should only be thrown from a deserializer (when it detects the socket closed between messages).
