Best way to Impute categorical data using Groupby 

We know that we can replace the nan values with mean or median using fillna(). What if the NAN data is correlated to another categorical column?

What if the expected NAN value is a categorical value?

Below are some useful tips to handle NAN values.

Definitely you are doing it with Pandas and Numpy.

import pandas as pd
import numpy as np

ngroup

cl = pd.DataFrame({
'team':['A','A','A','A','A','B','B','B','B','B'],                   'class'['I','I','I','I','I','I','I','II','II','II'],
'value': [1, np.nan, 2, 2, 3, 1, 3, np.nan, 3,1]})

Image for post

Lets assume if you have to fillna for the data of liquor consumption rate, you can just fillna if no other data is relevant to it.

But if the age of the person is given then you can see a pattern in the age and consumption rate variables. Because the liquor consumption will not be in same level for all the people.

An another example is fillna in salary value could be related with age, job title and/or education.

In the above example, let assume that columns test and class are related to value.

Using ngroup you can name the group with the index.

Procedure To Become An Air Hostess/Cabin Crew

Minimum educational required – 10+2 passed in any stream from a recognized board.

The age limit is 18 to 25 years. It may differ from one airline to another!

 

Physical and Medical standards –

  • Females must be 157 cm in height and males must be 170 cm in height (for males). This parameter may vary from one airline toward the next.
  • The candidate's body weight should be proportional to his or her height.
  • Candidates with blemish-free skin will have an advantage.
  • Physical fitness is required of the candidate.
  • Eyesight requirements: a minimum of 6/9 vision is required. Many airlines allow applicants to fix their vision to 20/20!
  • There should be no history of mental disease in the candidate's past.
  • The candidate should not have a significant cardiovascular condition.

You can become an air hostess if you meet certain criteria, such as a minimum educational level, an age limit, language ability, and physical characteristics.

As can be seen from the preceding information, a 10+2 pass is the minimal educational need for becoming an air hostess in India. So, if you have a 10+2 certificate from a recognized board, you are qualified to apply for an interview for air hostess positions!

You can still apply for this job if you have a higher qualification (such as a Bachelor's or Master's Degree).

So That I may recommend, joining Special Personality development courses, a learning gallery that offers aviation industry courses by AEROFLY INTERNATIONAL AVIATION ACADEMY in CHANDIGARH. They provide extra sessions included in the course and conduct the entire course in 6 months covering all topics at an affordable pricing structure. They pay particular attention to each and every aspirant and prepare them according to airline criteria. So be a part of it and give your aspirations So be a part of it and give your aspirations wings.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format

pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

  1. Design the PCB using your favorite CAD or drawing software.
  2. Print the top and bottom copper and top silk screen layers to a PDF file.
  3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
  4. Use a Gerber viewer to double-check the output against the original PCB design.
  5. Make adjustments as needed.
  6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

Create Pagination Using jQuery

In this article, we will see how to create pagination using jquery. We will create jquery pagination using multiple ways. You can create pagination using different ways like creating pagination using simple HTML, you can create pagination in laravel using paginate() method. Also, create pagination laravel livewire, pagination using bootstrap.

We will create simple jquery pagination. Also, create pagination using jquery without a plugin and create jquery pagination with next and previous buttons

So, let's see dynamic pagination in jquery and bootstrap pagination in jquery

Example:

In this example, we will create pagination using jquery without using a plugin. Also, you can customize the pagination.

Создание пагинации с помощью jQuery

В этой статье мы увидим, как создать пагинацию с помощью jquery. Мы создадим разбиение на страницы jquery, используя несколько способов. Вы можете создать разбиение на страницы, используя разные способы, такие как создание разбиения на страницы с помощью простого HTML, вы можете создать разбиение на страницы в laravel, используя метод paginate(). Кроме того, создайте разбиение на страницы laravel livewire, разбиение на страницы с помощью бутстрапа.

Мы создадим простую пагинацию jquery. Кроме того, создайте разбиение на страницы с помощью jquery без плагина и создайте разбивку на страницы jquery с помощью кнопок «Далее» и «Предыдущий».

Итак, давайте посмотрим динамическую нумерацию страниц в jquery и бутстраповскую нумерацию страниц в jquery.

Пример:

В этом примере мы создадим пагинацию с помощью jquery без использования плагина. Кроме того, вы можете настроить пагинацию.
