我希望添加一列并根据条件在每一行中更新它

Question

Input Dataset

For the above dataset, write a python or SQL command such that it returns the following

For each set of assignmentID, if the correct value is 1, append a new column with value 1 In case there are multiple rows with same assignmentid, then put 1 in new column only when there atleast 3 1's or at the last. Expected Output (First Column is only for ref to represent that there are rows with multiple assigment ID

My logic was

> a = [0,1,1,1,0,1,0,1] counter = 0 for i in a: 
>     if (a[i] == a[i+1]):
>       counter=counter+1
>     else:
>       counter=0 
>     if (counter>=3):
>       break if (counter==3):   print("Mastered") else:   print("WheelSpinning")

But I am not sure how to run this through the dataset or write it as SQL for above data.

Answer 1

If you wish to use python, Then here is an example, Take the last index in each row and append an element that saitisfies your conditions while iterating through every row of your dataset.

You could use sequel to retrieve all the data: SELECT * FROM TABLE_NAME
