7 min readTo read a nested XML file using Python Pandas, you can follow these steps:Import the required libraries: import xml.etree.ElementTree as ET import pandas as pd Load the XML file using xml.etree.ElementTree: tree = ET.parse('path_to_xml_file.xml') root = tree.getroot() Create an empty DataFrame to store the extracted data: data = pd.

7 min readTo expose a GraphQL field with a different name, you can make use of the @SerializedName annotation (assuming you are using a Java-based GraphQL server). Here are the steps to achieve this:Open the GraphQL schema file and locate the field you want to expose with a different name.Inside the schema definition, attach an annotation called @SerializedName("newFieldName") just above the field you wish to rename. Replace "newFieldName" with the desired name.

6 min readTo create a column based on a condition in Pandas, you can use the syntax of DataFrame.loc or DataFrame.apply functions. Here is a text-based description of the process:Import the Pandas library: Begin by importing the Pandas library using the line import pandas as pd. This will make all the Pandas functions and methods available to you. Load the data: Load your data into a DataFrame. You can use the pd.
-
8 min readTo return data from a GraphQL mutation, you can follow these steps:Define a mutation: Create a mutation definition in your GraphQL schema, specifying the input parameters and the return type. For example: type Mutation { createUser(name: String!, email: String!): User! } Here, createUser is the mutation name, and it takes name and email as input parameters. The exclamation mark (!) indicates that these fields are required. The return type is User.
-
7 min readTo apply a function across two columns in Pandas, you can use the apply() function along with a lambda function or a custom function. Here is how you can do it:Import the necessary libraries: import pandas as pd Create a DataFrame: df = pd.

8 min readTo consume a GraphQL API with Vue.js, you need to follow a few steps:Install the required dependencies: Begin by installing the necessary packages using npm or yarn. These typically include apollo-boost, graphql, graphql-tag, and vue-apollo. These packages will enable you to interact with GraphQL in your Vue.js application. Create a GraphQL client: Set up your GraphQL client by importing ApolloClient from apollo-boost and creating a new instance of it.

6 min readTo get a percentage of a Pandas DataFrame, you can use various methods depending on what exactly you want to calculate. Here are a few common scenarios:Row percentage: To calculate the percentage of each row relative to its sum, you can utilize the div function along with the sum function and set the axis parameter to 1. This will divide each element in a row by the sum of that row and give you the percentage.
-
10 min readTo make a join using GraphQL, you can use GraphQL's resolver functions to fetch data from different sources and then combine them into a single result.First, define the GraphQL schema, which includes the types and fields of your data. For example, let's assume you have two types, User and Post, where each user can have multiple posts. type User { id: ID! name: String! posts: [Post!]! } type Post { id: ID! title: String! content: String! userId: ID.

11 min readGraphQL is a query language and runtime for APIs that was developed by Facebook. It offers several advantages over traditional REST APIs, making it a popular choice for many developers.One of the key benefits of GraphQL is its efficiency in data fetching. With REST, you often need to make multiple requests to different endpoints to fetch related data. In contrast, GraphQL enables clients to specify exactly what data they need, reducing over-fetching and under-fetching issues.

5 min readIn Haskell, the double data type represents floating-point numbers with double precision. By default, double values are displayed with a certain level of precision. However, if you want to change the precision of a double value in Haskell, you can use the printf function from the Text.Printf module.To begin, make sure to import the required module: import Text.Printf The printf function allows you to control the output format of a value, including its precision.

9 min readIn GraphQL, extending types refers to the process of adding additional fields and functionalities to existing types without directly modifying the original definitions. This allows for a flexible and modular approach to building the schema.There are a few ways to extend types in GraphQL:Object Type Extension: This method involves the addition of new fields, either scalar or object types, to an existing GraphQL object type.
