• how to change prettier format for react native

  my code formatting prettier didn't works well for react native, i don't understand where to config it but it works well with flutter

  from this code

        import { View, Text } from 'react-native'
      
      import React from 'react'
      
      export default function App() {
        return (
          <View>
      
      <Text>Apps</Text>   
  </View>
        )
      }
  

  it's formatted to this

  import {
    View,
    Text
  } from 'react-native'
  
  import React from 'react'
  
  export default function App() {
    return ( <
      View >
  
      <
      Text > Apps < /Text>
  
  
      <
      /View>

• Convert 2D meshgrid into a 3D array in Python

  I have coordinates (lat, lon) in a meshgrid, and data asociated with each "point". I want to export into a .csv and have each point asociated with the data i want to analyze. So far, my code looks like this.

  xx1,yy1=np.meshgrid(xx,yy)
  row_format = np.stack([z.ravel() for z in (xx1, yy1, data['Hs'])], axis=1)
  print(row_format)
  pd.DataFrame(row_format).to_csv('sample.csv')
  

  The data is in a dataframe that has a certain order. But the output is as follows:

  x	y	Hs
  265	19	0
  266	19	1
  267	19	2

  And it should be as follows, in order to make sense with the data order:

  x	y	Hs
  265	19	0
  265	18	1
  265	17	2

  I only need to make the "x" column to be the one with the "still" value while the "y" column goes through its values ("x" will change value once every "y" value has been written). Anyone know how to change that order? Or another way to get my desired output?

• Categorize similar transactions

  Given a list of transactions, some transactions are categorized, some transactions are not categorized. Find similar transactions and categorize them if possible. Similar transactions have the same targetAccount and the amount difference is not greater than 1000 (for all currencies) from the originally categorized transaction. If an uncategorized transaction is similar to more than one transaction, it should take the category from the one with the smallest amount difference. Transactions that cannot be categorized should still be included in the returned list. The returned list should preserve the order of the original list.

  categorizeSimilarTransactions(transactions)

  Input You can assume that the transactions parameter will always be present and valid. list of transactions (Transaction[])

  Output List of transactions(Transaction[]) with enhanced categorization if possible.

  This is what a categorized transaction looks like:

      {
        id: "bfd6a11a-2099-4b69-a7bb-572d8436cf73",
        sourceAccount: "my_account",
        targetAccount: "coffee_shop",
        amount: -350,
        currency: "EUR",
        category: "eating_out",
        time: "2021-03-12T12:34:00Z"
      }
  

  An uncategorized transaction does not have category property. This is what an uncategorized transaction looks like:

      {
        id: "0f0ffbf9-2e26-4f5a-a6c0-fcbd504002f8",
        sourceAccount: "my_account",

        amount: -1900,
        time: "2021-03-12T12:34:00Z"
      }
  

  The following two transactions are similar:

      {
        id: "bfd6a11a-2099-4b69-a7bb-572d8436cf73",
        sourceAccount: "my_account",

  I could find a solution but it's a brute-force approach & not efficient. Is there any other solution with less time complexity may be O(n) or O(log(n))/O(nlog(n)) which is easy to read & understand

        const categorizeSimilarTransactions = (transactions) => {

• SVG file imported as Vector in Android Studio not converted correctly

  I have an image of a dinosaur that I have converted to an SVG from Adobe Illustrator (I did not create this image which may result to may lack of knowledge on what the issue is).

  ^ [Image is in PNG format because SVG cannot be uploaded, but both formats look identical]

  However, whenever I upload this image into Android Studio using the "Configure Vector Asset" tool in the "Resource Manager" most of the image is transparent.

  ^ [As you can see most of the image is transparent]

  I have done extensive research on how to resolve the issue; however, I have not been able to resolve the issue. Although, I believe I have pin pointed the issue which is due to the fact that "The tool supports group elements for translation, scaling, and rotation. Groups do not support an opacity property" (from https://developer.android.com/studio/write/vector-asset-studio#svg). Unfortunately, even though I may be aware of what the problem is, I am unaware how to solve this issue. Any help would be greatly appreciated. Thank you.
• Adobe Pdf - Hiding buttons on PNG export

• PYZBAR how to get certain outputs from DECODE function

  I'm using python PYZBAR to decode QR code captured by real time cam.

  decode(input_frame)
  

  Naturally the output I get is as follows

  [Decoded(data=b'DATA', type='QRCODE', rect=Rect(left=50, top=179, width=255, height=254), polygon=[Point(x=50, y=433), Point(x=305, y=424), Point(x=302, y=180), Point(x=51, y=179)], quality=1, orientation='UP')]
  

  the output shows:

  • The data stored in the QR Code.
  • Code type (QRCODE).
  • The position of each corner of the QR Code in the frame.
  • Quality.
  • And the orientation of the QR Code (whether it up, down, left or right).

  I'm only concerned about the data stored in the QR Code and its Orientation

  How can I define them as a variable to use them later, something like the following pseudo code:

  x = orientation y = data stored in QR Code
  if x == up && y == DATA:
  ...........
  

  My goal is to read and decode QR Code data and orientation to navigate a robot like the video provided in the link.
