Given a test data from this link:

I would like to groupby poi column and select 2 rows for each group, then find common address part (the colored part from table above) for each group starting from left, ie., ceng are common for poi is 1, but it has been ignored.

For filter rows which has at least 2 rows for poi and select 2 rows for each group.

I implemented a static array, how can I convert it to a dynamic array?

I have completed this task: Write a program for approximating the function f(x) on the interval [a, b] by a given method, m is the number of points at which the function is known (the size of the table). The function type is set to get the values of the table (xi, yi), i=1,2,..., m and check the quality of the approximation. I designed the solution to this problem in a separate function, but I can't rewrite this task using a dynamic array.

Please tell me how to solve this problem using a dynamic array?

I am trying to create an animation using matplotlib. I have written the following code, in which I have created a function called update_plot(). This functions runs a loop, in which data change and plot() function is called. The plot() function clears old plot and redraws it. If I try to run a loop inside update_plot() function (even if it doesn't affect the plot), the canvas shows nothing. Does anyone know why this happens? Thank you in advance!

I am struggling with improving the speed of interpolation of a large dataset which I am interpolating using gridfit. I have already posted a question on stackoverflow but havent got a response

So, I am thinking of trying something alternate. My idea is that if I have a huge dataset, as shown by the Python code snippet below

I need to make a python script that takes 2 pieces of info from each row of an excel sheet and pastes it into a specific line of a txt file(formatted as c file). I used a lot of online resources to create this but facing this error. I'm a complete beginner to Python so if you could help, I'd greatly appreciate it. Thanks!

I want to have some box annotations inside a plot with matplotlib. Is there a way to specify a fixed width for the textbox? I want to be able to have some random text inside my annotation that gets adjusted automatically, not to the sides, but top down.

Here is a minimal example:

I am currently doing a meta-analysis using the metafor package in R. My dataset looks like that :

for a project, I have to create a table with 51 attributes in SQLite via Python using ORM, so defining the tables as classes. Structure is like this table, but with y1-y50, which are similar.

I’m trying to do a function to detect intersections between two circles. If yes it scores true, otherwise it scores false, but I think I got lost so it does not display what I want. If anyone can help me please . Thank you Surely I have incorrectly coded in javascript if there is a person who knows the answer I am all ears
