For loop to append list of strings to lists within nested list

for-loop json nested-lists nested-loops python

[enter image description here][1]I have a dataset that is a list of 3 nested lists (called “patients”). Each nested list contains a certain amount of observations. The first nested list contains 119 observations, the second one 9 and the third list contains 6 observations. These observations are dictionaries containing some keys such as “start time” and “end time”. Now I

Updating a 2D Array with the output results of a nested loop in Python

multidimensional-array nested-loops python

I have a nested loop where I calculate 10 distances, and store them in an array b_array. Then into a_array another array which will is to keep the results for every image. The problem is that my code overwrites a_array for every iteration even when it is outside the main function when I checked with print. Therefore, I end up

Python — Confusing result when combining for loop with while loop

for-loop nested-loops python while-loop

Hi I’m new to programming. I tried to use for loop and a nested while loop to calculate the sum of an arithmetic sequence on condition that the sum is no bigger than 100. I wrote the code below, but the output was 100 instead of the correct sum of the elements of the sequence (which should be 92). Could

Can anyone explain these python nested loop please

How do I include part of my code into ‘yield’?

Thank you for your time! Each products, sometimes have more than one model. I got the model ‘name’ and ‘price’ of the respective models within a single product via a for loop. But, how do I ‘transfer’ these details to the ‘yield’ section along with other variables of that same product? Below is my attempt, but i am not getting
