How to Check Column Nulls and Replace: Pandas

Image
Here is a post that shows how to count Nulls and replace them with the value you want in the Pandas Dataframe. We have explained the process in two steps - Counting and Replacing the Null values. Count null values (column-wise) in Pandas ## count null values column-wise null_counts = df.isnull(). sum() print(null_counts) ``` Output: ``` Column1    1 Column2    1 Column3    5 dtype: int64 ``` In the above code, we first create a sample Pandas DataFrame `df` with some null values. Then, we use the `isnull()` function to create a DataFrame of the same shape as `df`, where each element is a boolean value indicating whether that element is null or not. Finally, we use the `sum()` function to count the number of null values in each column of the resulting DataFrame. The output shows the count of null values column-wise. to count null values column-wise: ``` df.isnull().sum() ``` ##Code snippet to count null values row-wise: ``` df.isnull().sum(axis=1) ``` In the above code, `df` is the Panda

Python Program: JSON to CSV Conversion

Image
JavaScript object notion is also called JSON file, it's data you can write to a CSV file. Here's a sample python logic for your ready reference.  You can write a simple python program by importing the JSON, and CSV packages. This is your first step. It is helpful to use all the JSON methods in your python logic. That means the required package is JSON. So far, so good. In the next step, I'll show you how to write a Python program. You'll also find each term explained. What is JSON File JSON is key value pair file. The popular use of JSON file is to transmit data between heterogeneous applications. Python supports JSON file. What is CSV File The CSV is comma separated file. It is popularly used to send and receive data. How to Write JSON file data to a CSV file Here the JSON data that has written to CSV file. It's simple method and you can use for CSV file conversion use. import csv, json json_string = '[{"value1": 1, "value2": 2,"value3

JavaScript Vs JSON Top Differences

Today I woke up after my night sleep, and quickly I completed my daily routines. I thought a few minutes to write useful posts for my readers. I decided to write the differences between JavaScript and JSON. JavaScript Vs JSON Top Differences JSON Quick Insights JSON is simply a data-interchange format and, therefore, does not directly require the immediate knowledge of the JavaScript language. JSON a subset of the JavaScript language. Data exchange can occur between both browser and server and even server to server. The file extension is .json. You can structure the JSON as below: A collection of name/value pairs. An ordered list of values. An introduction to JSON read here JavaScript Quick Insights JavaScript is a text-based scripting language, whereby sequences of Unicode characters strung together. JavaScript supports two different types of data types. Primitive and non-primitive. Primitive data types the best example is the Object. The non-primitive examples are number, string, Boo

How to Learn JSON XML and Simplify Your AWS Task

JavaScript Object Notation (JSON) was invented by Douglas Crockford as a subset of JavaScript syntax to be a lightweight data format that is easily readable and writable by both humans and machines. In general, JSON is considered terse when compared to other interchange formats.  After you become familiar with JSON, you will find it fairly easy to read complex JSON data structures. Even though  JSON is based on a subset of the JavaScript programming language , it is considered language independent. JSON XML The flexibility of XML has made it increasingly prevalent in programming environments. Unlike the Unix® world, where configuration files are usually text files with either tab-delimited name/value pairs or colon-separated fields, configuration files in the open source world are often XML documents. Most well-known application servers also use XML-based configuration files. The Ant utility relies on XML-based files for defining tasks. Data Integration A tremendous amount of data in t
