QUESTION
This is part of my doubly linked list deque python code.
The 'appendleft' function written almost similar to the 'append' function is normally output. Why is the last 'append('apple')' code not output normally in the 'Group_of_append' function?
...ANSWER
Answered 2022-Mar-28 at 12:28Your appends work fine. Problem lies in your print_list function which stops when p.next is None. Which means your last element will not be printed because its next is None.
All in all, your logic for this list is very strange and could use a lot of rework, it would make finding mistakes like this one a lot easier for you. For example, this iterating through the whole list when appending even though you have both head and tail readily available in the deque object.
QUESTION
I have two examples of foldLeft that I cannot really grasp the logic.
First example:
...ANSWER
Answered 2022-Mar-27 at 21:07Does not
foldLeftaccumulate value that was earlier?
yes it does. It uses result of previous iteration and current element and produces new result (using the binary operator you have provided) so for the first example next steps are happening:
the start value of accumulator -
""acc = "",curr = "Plain"->" , Plain Donut "acc = " , Plain Donut ",curr = "Strawberry"->" , Plain Donut , Strawberry Donut "acc = " , Plain Donut , Strawberry Donut ",curr = "Strawberry"->" , Plain Donut , Strawberry Donut , Glazed Donut"
For the second example current value is simply ignored - i.e. multi can be rewritten as def multi(acc:Int, curr:Int):Int = acc*10 where curr is not actually used so foldLeft simply multiplies starting value (1) by 10 n times where n is number of elements in the sequence (i.e. (1 until 3).length which is 2).
Why does it not take any input variables (num and num1)?
foldLeft is a function which accepts a function. It accepts
a generic function which in turn accepts two parameters and returns result of the same type as the first parameter (op: (B, A) => B, where B is the the result type and A is sequence element type). multi matches this definition when B == A == Int and is passed to the foldLeft which will internally provide the input variables on the each step.

I cannot find anywhere how to convert a pandas dataframe to type datasets.dataset_dict.DatasetDict, for optimal use in a BERT workflow with a huggingface model. Take these simple dataframes, for example.

QUESTION
I'm still young to coding and cannot figure out better functions or results to some tasks by myself very often.
I have a question on tracking the original string after using str_extract_all for a specific pattern.
Here is an example data called "fruit".
index Fruit 1 apple 2 banana 3 strawberry 4 pineapple 5 bell pepperI used str_extract_all(fruit, "(.)\\1") to extract duplicated consonants, and get "pp", "rr", "pp", "ll", "pp".
Also tracked the original string (of those extracted results) by str_subset(fruit, "(.)\\1"). Here's what I get.
However, I want to know where "each" extracted result is from. Therefore, using str_subset cannot capture those results which are from the same string. The following dataframe is what I expect to gain.
I'm not sure if I explain my question clearly. Any feedbacks and ideas will be appreciate.
...ANSWER
Answered 2022-Mar-24 at 11:24Your code already did what you want. You just need to create an extra column to store the output of str_extract_all, like the following:
Since str_extract_all() returns a list, we'll need to unnest the list to become rows.
The final line of the code is to create a consecutive index (since "banana" is gone, index 2 will also be gone).

QUESTION
In my hypothetical example, people order ice-cream at a stand and each time an order is placed, the month the order was made and the number of orders placed is recorded. Each row represents a unique person who placed the order. For each flavor of ice-cream, I am curious to know the cumulative orders placed over the various months. For instance if a total of 3 Vanilla orders were placed in April and 4 in May, the graph should show one data point at 3 for April and one at 7 for May.
The issue I am running into is each row is being plotted separately (so there would be 3 separate points at April as opposed to just 1).
My secondary issue is that my dates are not in chronological order on my graph. I thought converting the Month column to Date format would fix this but it doesn't seem to.
Here is my code below:
...ANSWER
Answered 2022-Mar-01 at 20:46In these situations, it's usually best to pre-compute your desired summary and send that to ggplot, rather than messing around with ggplot's summary functions. I've also added a geom_line() for clarity.
QUESTION
I am new to Python, and I am trying to use Python to query a Microsoft SQL Server database. The data is returned in this format:
(('orange,apple,coconut',), ('lettuce,carrot,celery',), ('orange,lemon,strawberry',))
What I am trying to do is check to find a match, to see if some data from another data table exists in that data from SQL Server.
When I try to use the "in" to check, it does not work for me. I thought if I could convert the data (a tuple of tuples) into a list, then I could more easily search and match. But that doesn't work because there are some brackets around each list element. At least, that is the what I think because, if I manually recreate the list without the extra brackets, then I can search successfully.
I am wondering if there is a way to remove that extra bracket. Or, maybe there is a better approach. I have read several posts here and other articles, and so far, I have not found an approach.
Here is what I have tried. As you can see, the final one works, but that is what i have created manually.
