            Append data to CSV using a nested loop
            Asked 2022-Jan-11 at 13:42

            I am trying to append data from the list json_responsecontaining Twitter data to a CSV file using the function append_to_csv.

            I understand the structure of the json_response. It contains data on users who follow two politicians; 5 and 13 users respectively. 1) author_id, created_at, tweet_id and text is in data. 2) description/bio is in ['includes']['users']. 3) url/image_url is in ['includes']['media']. However my nested loop does not append any data to sample_data.csv? and it throws no error. Does it have something to do with my identation?

            Looks like the else branch of if 'description' in dic: is never executed. If your code is indented correctly, then also the csvWriter.writerow part is never executed because of this.

            That yields that no contents are written to your file.

            A comment on code style:

            • use with open(file) as file_variable: instead of manually using open and close. That can save you some trouble, e.g. the trouble you would get when the else branch would indeed be executed and the file would be closed multiple times :)

            Why does my loop only append the last item from a list?
            Asked 2022-Jan-10 at 16:56

            I am trying to extract an element from a list and append it to a CSV file.

            json_response is a list containing data on Twitter users who follow two politicians. For the first politician there are 5 tweets/users and for the second politician 13 tweets/users as can be seen from the structure of json_response. I want to extract the description for each user which is contained in ['includes']['users']. However, my function only extracts the last description 5/5 user and 13/13 user for each politician.

            My knowledge regarding JSON-like objects is limited.

            How to reformat a corrupt json file with escaped ' and "?
            Asked 2021-Jun-13 at 11:41

            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:

            1. A simple data.replace('\'', '\"') is not possible, as the "text" fields contain tweets which may contain ' or " themselves.
            2. Using regex, I was able to catch some of the instances, but it does not catch everything: re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
            3. Using literal.eval(data) from the ast 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):

            JavaScript base64string -> binary values -> [Integer] ... performance improvement
            Asked 2021-Apr-17 at 08:17

            I am working with Parse Server and am trying to speed up queries that use a bloom filter.

            Each document has a field bf with number value in range 0...bloomSize, for example document Id "xyz" is hashed as bf = 6462

            The query then loads binary bloom filter values that are encoded and saved in base64 string. To make use of indexed query in Parse Server / MongoDB I need to generate an array of integers that I can compare then with the above mentioned field. So the base64 string needs to be decoded and for each 0 in binary data I have to append an integer of that 0 value position. Currently I am using following snippet:

            It should improve a bit when you avoid the conversion to string with .toString(2). Also the repeated i*8+l can be avoided by using a separate counter variable:

            You setUp data with setUp. Furthermore you should save the primary key, and use this since a database can use any primary key. Depending on the database backend, and the order of the test cases, it thus can create an object with a different primary key:

            This shouldn’t be a strapi issue. First you need to have an access from outside to google cloud postgres database. I’m not familiar with google cloud services, but from documentation there seem to be a couple of things to do to grant access to database.

            More info from documentation:
            https://cloud.google.com/sql/docs/postgres/connect-external-app#appaccessIP

            Basically you grant access for connection from outside and then you add that connection information to your strapi config file.

            I noticed your host: is not pointing to http:// or https:// but to some google server’s local address.
