QUESTION
The goal is to replace the last line of a document. The last line always starts with a $. I am using a find here but don't have to, I couldn't get any other way to function.
I have used replace.text successfully within find but due to some conditions I can't use that without tons of if statements running different Finds.
Everything seems to be working I try except for going to the end of the page or expanding to delete/replace the entire line after the $.
Specifically the .Expand function doesn't work for me the 10 different ways I've tried. and .EndKeys never works for me. (I have tried every combination of WordDoc.Expand WordApp.Expand WordSelection.Expand setting activedocument etc.)
The code is a bit of a mess at this point. The For Each oRange
is the only part with issues and is my 10th iteration of trying to get it to work by now.
ANSWER
Answered 2021-Jun-11 at 20:55Your code isn't working because WordSelection
doesn't get moved after the Set
statement. You can accomplish what you need just using the Range. You should also check that Find actually found something.
QUESTION
I want to create and save a number of sequential plots so I can then make an mp4 movie out of those plots. I want the color of the plot to depend on z (the value of the third axis):
The code I am using:
...ANSWER
Answered 2021-Jun-07 at 07:53The poster wants two things
- lines with colors depending on z-values
- animation of the lines over time
In order to achieve(1) one needs to cut up each line in separate segments and assign a color to each segment; in order to obtain a colorbar, we need to create a scalarmappable object that knows about the outer limits of the colors.
For achieving 2, one needs to either (a) save each frame of the animation and combine it after storing all the frames, or (b) leverage the animation module in matplotlib. I have used the latter in the example below and achieved the following:

I am trying to understand a Mathematica code so that I can replicate it in python:
My function in Mathematica -
Deulab[c_, yh1_, a_, b_] := {c - (EULab[c, yh1, a, b] - 1) * 0.3, yh1, a, b}
where I have already defined EULab
above.
What does the curly bracket mean and how can I interpret this code and then replicate it in python?

QUESTION
I've got two png image sequences with 30 frames each i'm trying to blend together. The problem is that some of the images are in the rgb24 color space while some are in rgba. Blending the two 30-frame animations together causes it to loose frames - the output is only 26 frames long and the two individual strips out-of-synch.
Command used:
...ANSWER
Answered 2021-May-14 at 09:19The issue is that the pixel format within each input changes mid-way. This causes the filtergraph to reinitialize and buffered frames get dropped.
Suppress reinitialization and convert to a command pixel format before blending.

...ANSWER
Answered 2021-May-13 at 13:59The logic is inefficient, and it has nothing to do with the use of streams.
Your outer loop should be on "groups", and then check against the set of values of mapping, which is O(1) complexity. Something like:

My python code starts in a specific directory. From this directory, I would like my script to automatically create a new directory by today's date and then change to that directory.
...ANSWER
Answered 2021-Apr-22 at 11:22- You didn't close the string correctly. You forgot the ending '
- You did not use f-strings correctly. To use a variable in a f-string, surround it with curly braces.
