QUESTION
I am trying to reduce lines of code because I realized that I am repeating the same equations every time. I am programming a contour map and putting several sources of intensity into it. Until now I put 3 sources, but in the future I want to put more, and that will increase the lines a lot. So I want to see if it is possible to reduce the lines of "source positions" and "Intensity equations". As you can see the last equation is a logaritmic summation of z1, z2 and z3, is it possible to reduce that, any idea?

Answered 2021-Jun-15 at 15:45You could iterate over certain parts in a loop.
I tried to keep the same format overall and just rearranged the code to show how you might do it.

QUESTION
I'm experienced with Pandas but stumbled upon a problem that I can't seem to figure out.
I have a large dataset ((40,000, 16)) and I am trying to group it by a specific column ("group_name" for this matter) and then for each group apply the following rules so it'd merge into one row per group:
- x1, x2, x3 are the "important" columns, if one row has less nulls than the others, take it. (see example with row D)
- If there are conflicts in any column, it's arbitrary and we can pick whatever.
- Combine the nulls on the important fields (x1, x2, x3), see example with row A.
Here is an example with 6 rows that should turn into 4 groups (aka 4 rows).
So far I have
groups = df.groupby['group_name']
I tried many other solutions such as summing each group, applying a transformation, aggregating by each 'important' column, merging on each 'important' column and more. Each solution brought it's own problems so I'm offering this question here without limiting people to a certain way.
Also, I spent nearly two days combining different solutions from other questions but none has seem to work. Perhaps I've missed something.
- Please note that since this is a large dataset, I'd very much like to avoid using
for
loop on each group since efficiency is something to consider here.
I hope I explained everything properly, please let me know if something is unclear.

QUESTION
I'm trying to run a macro that does three things:
- Loops through a series of excel files
- Identifies a row containing the text "project attributes"
- Uses this row to set a range to perform a merge operation
I constructed this out of building blocks of code I found elsewhere, and I know that each works independently (i.e. I can run through all files without performing actions, and I can identify the row and perform the merge) but when I combine them, I get a run-time 91 error "Object variable or With Block variable not set" - associated with this line " FindRowNumber = FindRow.Row ".
Looking for guidance as to how I can avoid having this variable set to "Nothing" as it appears in the Watches window.
Thanks!

QUESTION
I have a function 'get_number(code, attribute)' that outputs a specific section of a code that is associated with a specific piece of information. But I'm not sure how I would use this function within 'print_description(code)' so I can get the specific section of the code when the function only has one return.
Under the 'print_description(code)' docstring, I want to replace those equations 'get_number(code, attribute)'

I have written the following assembly code.
It's displaying the output of writeint as +0
But When I put the debug point on the line before writeint and look at the registers
I see EAX=0000BFBE
. As per my understanding writeint should print the value of EAX
register. What could be the reason that it's showing +0?
