I am trying to develop an app in Flutter/Dart and I'm stuck on this.

PROBLEM:

I'm getting this data from the db :

The script below takes one string input as a polyline and returns a data frame with the corresponding latitude/longitude pairs.

I would like to input to be a data set as follows:

and the output to be (keeping the ActivityID)

I was thinking along the lines of iterating over the input dataset to do this but I've read here that's not a great idea performance wise.

Please can someone advice how to do this in Python?

What I want: to create a function to insert a line break between every letter of a character variable in R.

What I tried: but it didn't work

I am new to shiny and just built this shiny app using the ToothGrowth data available in R. A summary of the data is as follows:

I have the following pandas dataframe that has thousands of rows:

I'm unable to read gzip encoded response in a Symfony projet. Here is my service :

I have 2 lists, it is matching by order. List 1 contained 4 datasets, List 2 contained 4 datasets.

The output returns 2 new lists, one for list 1, and one for list 2.

Condition:

If any dataset from list 1 have the same titles, I create sublist

I am currently trying to read a large compressed CSV file which I uploaded to Github.

below is the code I'm using to do so

I'm trying to explode a column of a dataframe to get multiple rows. The column to explode it's called keywords, which are a list of emotions returned as keywords from the package FlashText. This means if a keyword is in the text column (column with sentences), then it will return that emotion or multiple emotions corresponding to that sentence

If I use an example dataframe created by me, this works perfectly with an expected output, however when applied to the dataframe explode it returns a random combination of rows.

I thought this unexpected results were because the dataframes have duplicate indexes, however, drop them gaves the same wrong result.
