Conditional Logic in ASP.net page

September 1, 2022 by Magenaut

I have some code that prints out databse values into a repeater control on an asp.net page. However, some of the values returned are null/blank – and this makes the result look ugly when there are blank spaces.

Check if something is (not) in a list in Python

August 20, 2022 by Magenaut

I have a list of tuples in Python, and I have a conditional where I want to take the branch ONLY if the tuple is not in the list (if it is in the list, then I don’t want to take the if branch)

August 18, 2022 by Magenaut

I have a large numpy array that I need to manipulate so that each element is changed to either a 1 or 0 if a condition is met (will be used as a pixel mask later). There are about 8 million elements in the array and my current method takes too long for the reduction pipeline:

Pandas select rows and columns based on boolean condition

August 16, 2022 by Magenaut

I have a pandas dataframe with about 50 columns and >100 rows. I want to select columns 'col_x', 'col_y' where 'col_z' < m. Is there a simple way to do this, similar to df[df['col3'] < m] and df[['colx','coly']] but combined?

How do you set a conditional in python based on datatypes?

August 12, 2022 by Magenaut

This question seems mind-boggling simple, yet I can’t figure it out. I know you can check datatypes in python, but how can you set a conditional based on the datatype? For instance, if I have to write a code that sorts through a dictionary/list and adds up all the integers, how do I isolate the search to look for only integers?
