QUESTION
Problem
I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.
Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.
This is what I tried so far:
- A simple
data.replace('\'', '\"')
is not possible, as the "text" fields contain tweets which may contain ' or " themselves. - Using regex, I was able to catch some of the instances, but it does not catch everything:
re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
- Using
literal.eval(data)
from theast
package also throws an error.
As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.
Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

that are causing the problem are only in the tweets and desciption
you could try that
QUESTION
I am encountering an issue with Neo4j where the results for the same query change after applying the below:
- an index on a property for nodes with a given label
- a constraint that asserts the existence of the same property for nodes with the same label as above
- Neo4j version: 4.2.1 Enterprise, default runtime (slotted)
- Neo4j Desktop 1.4.1
- Operating system: macOS Big Sur Version 11.4
Create one set of nodes and relationships by running the following:
...ANSWER
Answered 2021-Jun-09 at 22:27Yes, this is a good illustration of a bug that was fixed in Neo4j 4.2.3, and happens when the label is present in an OPTIONAL MATCH on a previously-bound variable.
From the changelog:
Fixed a bug where an index scan would be used to solve an OPTIONAL MATCH incorrectly.
https://github.com/neo4j/neo4j/wiki/Neo4j-4.2-changelog#423
The workaround until the fix was to remove the redundant label.
We highly recommend staying updated to at least the latest patch for your minor version to avoid known and fixed bugs.

Answered 2021-May-30 at 08:08Use a grid layout with flex on the logo element. using grid-layout you can express how wide you want the columns to be using grid-template-columns:
then call the grid-area on each selector with in the grid parent. You may need to tweak a bit to your liking depending on what view ports you are going for.
Use flex on child items you wish to align in a row. Simple Ul/li for links...

QUESTION
I am using the Google TextToSpeech API in Node.js to generate speech from text. I was able to get an output file with the same name as the text that is generated for the speech. However, I need to tweak this a bit. I wish I could generate multiple files at the same time. The point is that I have, for example, 5 words (or sentences) to generate, e.g. cat, dog, house, sky, sun. I would like to generate them each to a separate file: cat.wav, dog.wav, etc.
I also want the application to be able to read these words from the * .txt file (each word/sentence on a separate line of the * .txt file).
Is there such a possibility? Below I am pasting the * .js file code and the * .json file code that I am using.
*.js
...ANSWER
Answered 2021-Apr-27 at 16:58Here ya go - I haven't tested it, but this should show how to read a text file, split into each line, then run tts over it with a set concurrency. It uses the p-any and filenamify npm packages which you'll need to add to your project. Note that google may have API throttling or rate limits that I didn't take into account here - may consider using p-throttle library if that's a concern.

I have just started learning Python from the book 'Python Crash Course: 2nd edition' by Eric Matthes. I am using Windows. Most of the times, I open .py files directly by double-clicking on them from Windows file explorer.
But when I tried to run the following program in the same way, I found that it closed the cmd window immediately when the while loop stops even if it is supposed to continue:
...ANSWER
Answered 2021-May-25 at 06:29When your program ends the while loop, it actually does prints the stuff and the program exits, so basically it does that (prints the text) but you don't see it because the program exits and console closes, if you open it through CMD when the program exits the console doesn't closes and the text keeps on screen.
