I have two dataframes, one with ITM JPM Puts from 2011, and another with interest rates, dividends etc. A small example of the two frames are;

I have the following DataFrame containing stock data from several finance institutions.

I have come across some trouble while trying to filter my dataset.

My dataset contains information regarding the Dow Jones Index data, there are 750 observations and 16 variables. (I will attach a screenshot as pasting the code makes it look messy and complex):Dataset

For more information, I have divided the Dow Jones Index data into subsets named Quarter_1 and Quarter_2. My goal was to use the Quarter_1 data and split the stocks into groups by their industries for my assignment. It has worked before but all of a sudden, the code does not recognize the variable "Stock".

I'm trying to list the codes and descriptions that are used in a "person" table. There are many codes in the "code_table" but I don't want to list unused codes.

I have a "person" table that has a record for each time a person is changed... in particular, I'm interested in the "person_code" field. Every person record has a date_revised value that indicates when the change was made. The person table has an identity primary key (person_id) and a person identifier (person_int) for each person.

I have a "code_table" which has records for each time it's changed, again containing a date_revised field. It has a "code_type" field that matches person_code in the person table and "code_data" which is the description of the code. Code_table also has a identity primary key and an identifier (code_group + code_type)

So, the data might look like: person:

I have a csv file / pandas dataframe which looks like this. It contains various portfolio compositions for a portfolio which is re-balanced everyday according to my own calculations.

I have a dataframe with a column for sentences (text). I would like to perform name entities replacement: I have a list whose elements are stocks information

I'm trying to write a function that builds an array where each value of the array is a value pulled from an API using a unique url, once the value is fetched from the API it is pushed into the existing array.

Basically when the function is called I want to populate an array with fetched API data for each stock ticker listed in the List, what i have so far doesnt seem to be working though

When writing to a file I use the following code. Here it's upper case, but I've also seen the encoding in lower case utf-8.

I'd like to output a table using "Premises" model in Django admin. In addition I'd like include the output in this table of an additional column, say "last utility payment". It is actually a column in a related table. There may be no payment in the database so admin should able to see either an empty cell or the date of payment.

I was able to write a DB query that displays the information I need. Its significant and worked part is given below:
