QUESTION
so first of this is my first time asking a question here so forgive me if I make any mistakes.
My Problem is as follows: I'm using python to sort through a bunch of images. The images are sorted by many criteria, one of which is the text inside the Image. I've got OCR working and have a list of "bad" words which arent supposed to be in the Image. The problem is that the OCR often confuses some letters, for example e and a. The question is if there is an easy way to generate similar looking words.
Like create_similar("test")
And output would be ["test", "tast" "lest"]
and so on.
So I could use that as the list of Bad words and avoid false negatives. If I'm just missing a really obvious solution, please tell me. I've been trying for hours now and just can't get it to work.
ANSWER
Answered 2021-Jun-13 at 22:18I really recommend this article by Peter Norvig on how to build a spelling corrector. In it, you will find the following function that returns a set of all the edited strings (whether words or not) that can be made with one simple edit. A simple edit to a word is a deletion (remove one letter), a transposition (swap two adjacent letters), a replacement (change one letter to another) or an insertion (add a letter).
QUESTION
I am developing an form where in, there are 3 drop downs in a row, and the last drop down can take multiple values. Also, there is an option to add or delete a row. When user adds a row, a new row with the three drop down appears.
I have used React, React Semantic UI, Hooks, Typescript to implement this.
Now, I am trying to get the value of the selected items from the dropdown when the form is submitted. But, not sure what i'm missing to achieve this. When I add a row, the new row is taking the selected items of the top row.
My code is like this:
...ANSWER
Answered 2021-Jun-10 at 14:17There are few things which you need to change in your code.
when using Formik there is no need to maintain state explicitly to hold the form values . Formik will take care of it .
You are just changing the values but not notifying the formik to change its state.
Since you are rendering the array of Fields , you can make use of the Formik
FieldArray
component which comes with the bunch of helpers like pushing a new row, removing the row and updating the value of a field within each row.Your submit was not working because you have the submit button outside the
component . So clicking on
submit
button will not call theonSubmit
ofFormik
.
Have refactored your code to make use of the FieldArray .
QUESTION
I am currently trying to scrape this yelp page 'https://www.yelp.com/biz/taste-of-lebanon-west-springfield'. I first grab all the divs that contain their services so I can know if they offer takeout, delivery, etc. Then after I loop through to determine if they contain the green checkkmark span but anytime I search it does not stay within the parent element even though I am using that element as my search driver.
I am trying to find all the spans that contain this class 'icon--24-checkmark-v2 css-yyirv3' but whenever my script reaches the loop instead of staying within the parent element when searching the find_element_by_xpath will search the entire page so it always comes up as true even though there will not be a span with a matching class in that element. How do I get my search to stay within the parent element when trying to find a child element by xpath?

QUESTION
I have a data frame in which I have an id variable fruit
in the example. For some of the other variables, there is only one corresponding value to each id variable taste
, ranking
while for others, there are multiple color
,origin
.
I would like to collapse the data frame so that each id variable has one row. For the variables that have multiple values, I could ideally store them as a list.
However, I can't figure out a way to do this. Here is what I tried using summarise
and unique
for the variables with multiple values. However, I just got back the original data:

Answered 2021-Jun-05 at 19:34We can use summarise
with across

elements in a list
after doing a grouping by the columns of interest
QUESTION
I have a MultiIndex
data frame called df
with 3 indexes
(Fruit, Color, Taste). I want to search 1 specific index

is an index
in the dataframe not just a column.

QUESTION
My issue here is that my Xmobar says that it's "Updating..." when I provide the layout with a path to a C script (the executable)that I hacked together. I included Run Stdinreader and that made no dent on the issue.
I was under the impression that if a script can output to the terminal, it could to Xmobar. This C script is responsible for printing a quote to the terminal based on conditions specified. I don't need help with the script itself (although it is rushed and could be better constructed). I just want to know:
Is this an issue with an incompatibility with Xmobar and C? Or, did I forget to do something that will make the taskbar spit out the correct output?
My Xmobar Config is:

Answered 2021-Jan-27 at 23:23Did more research today. The problem here is that %% counts as an argument to "run" something, but above it is where it's supposed to be defined. It's not.
I just used %diskspace% for a new script that outputs my Sink volume. It would work the same with the C script.

...ANSWER
Answered 2021-Jun-02 at 14:22I'm not sure Upserts in Laravel Excel are what you want. Specifically, there is a condition listed in the documentation that is (in my opinion) overly restrictive.
All databases except SQL Server require the uniqueBy columns to have a "primary" or "unique" index.
To import spreadsheet data in a custom way, you can always use the ToCollection
concern. This will give you full control over how the entries are saved.
https://docs.laravel-excel.com/3.1/imports/collection.html
Use the updateOrCreate()
method to look for existing entries with the options you have specified by passing them in the first array, with the remaining data in the second array.

QUESTION
I have spent whole day trying to figure this out. I want to update course recipes from my database (MongoDB) using my REST API call (Node.js with Express) by sumbiting input fields with new values of the recipe. I tried to show previous values by using input value="", but as I learned this makes it to be static. I tried to change it into dynamic accordingly to what I found online however none of tutorials I found would show what I am looking for. As you can see in code below I am trying to PUT new data that was previously set using setState(). Sadly I do not know how can I do it like this. Could you tell me if it is even possible and if so where can I learn to do it?
Here is code from React:
...ANSWER
Answered 2021-Jun-02 at 12:00When button is clicked and the PUT request is made and the values are updated - you must also tell your component states to mirror the new changes from the backend.
Therefor you must call old() method (which handles the fetching request and set states) after your PUT request. This is makes sure that your component states is sync with the values from the database.
Here is a small modification to your update() method (I marked it with an arrow):
