rbc | R boot-camp | Code Analyzer library

In the code below, i'm trying to replace mean instead of missing values but i can't get a result for my attempts because this data includes special characters which is "?". When there is no question marks in the data this code works data.fillna(data.mean()). When i tried to impute method, i got the following error:

ValueError: Cannot use mean strategy with non-numeric data: could not convert string to float:

Also this data includes string columns with missing values, how can i fix missing values in the string columns (column rbc for example)?

here is my data: https://easyupload.io/te2mbc

I'm trying to extract the main article text from some pages on newswire website using beautiful soup. But instead of the text output. I get an output that says "Searching for your content..."

I would highly appreciate any help. I seem to be doing something fundamentally wrong here. (I'm sorry about that, if I'm doing it the wrong way as I'm a beginner in coding)

I am going to extract text from a picture using OpenCV in Python and OCR by pytesseract. I have an image like this:

Then I have written some code to extract the text from that picture, nut it does not have enough accuracy to extract the text properly.

That is my code:

I have a Dataframe consisting of medical records which looks like this

My plan is to convert it to a list of dictionary(s) which would look something like this

Hi I have this sting in a Dataframe (column is named value)

This ANTLR4 parser grammar errors a 'no viable alternative' error when I try to parse an input. The only rules I know of that matches the part of the input with the error are the rules 'retblock_expr' and 'block_expr'. I have put 'retblock_expr' infront of 'block_expr' and put 'non_assign_expr' infront of 'retblock_expr' but it still throws the error.

input:

print(do { return a[3] })

full error:

line 1:11 no viable alternative at input '(do { return'

parser grammar:

When I run my grammar (lexer and parser) in powershell, it produces these errors:

I have the Columns that have a corresponding Subject ID, measurements, RPT, Status, and FLAG. I want to update the "FLAG" column "To be removed" or "Do not Remove" for the rows that have the Maximum RPT value of that particular measurement and subject ID.

Constraints: The flag "to be removed" should be set for the value that has max RPT and the status should be "Current" of that particular subject ID.

How can I do it in Excel?

I have two jsonb value. I would like to merge it however I stuck to combine it together. This is my code
