Create a Client class that interacts with an SQLDatabase Server (provided below). The Client sends a SQLQuery to the SQLDatabase and receives a Dataframe from the SQLDatabase. The class should contain the default __dunders__ and potentially introduce some custom __dunders__. The SQLDatabase Server: import pandas as pd import sqlite3 class Server: def __init__(self, database): self.conn = sqlite3.connect(database) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.conn.close() def __repr__(self): return f"Server({self.conn})" def execute_query(self, query): cursor = self.conn.cursor() cursor.execute(query) columns = [desc[0] for desc in cursor.description] results = cursor.fetchall() df = pd.DataFrame(results, columns=columns) cursor.close() return df

In Python, create a Server Class that enables interaction with a SQLDatabase. The users of your SQLDatabase server can send SQLQueries to the SQLDatabase. The SQLDatabase handles the SQLQuery and retrieves the Query's data in a DataFrame format. Your class should incorporate the default __dunders__ (underscores) and may also include additional custom __dunders__.

Hello! I need to create a new Order with an API but I can't get it to work. My code so far is: //POST (create a new record (table)) http:API, (with additional body elements, OUCU=****, password=******, client_id=1. latitude=89, longitude=-20). function orderCreated() { let data = {oucu:"xxxxxxx",password:"xxxxxxx",client_id: 1,latitude:89,longitude:-20};var formBody = [];for (var property in data) {var encodedKey = encodeURIComponent(property);var encodedValue = encodeURIComponent(data[property]);formBody.push(encodedKey + "=" + encodedValue);}formBody = formBody.join("&"); fetch('httpAPI)', {method: 'POST',headers: {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'},body: formBody})}; So, it must retur: {"status" : "success","data" :[{"id":"****","client_id":"***","date":*************","latitude":"****","longitude":"-******"}]}

Write a Java program that connects to a SQLite database. Create a table called Horses with the following fields: id (integer): a primary key and not null name (text) breed (text) height (real) birthday (text) Next, insert the following data row into the Horses table: id: 1 name: 'Babe' breed: 'Quarter Horse' height: 15.3 birthday: '2015-02-10' Output all records from the Horses table.

awk is similar to the SQL language in that you can query certain records. What command below will search the the file /etc/passwd file by locating all users that have a default shell '/bin/bash' and print the first column (which is the user name). awk -D: '$7 == "/bin/bash" {print $3}' /etc/passwd Give this to your new intern to figure out. awk -F: '$4 == "/bin/bash" {print $10}' /etc/passwd awk -F: '$7 == "/bin/bash" {print $1}' /etc/passwd awk -F: '$1 == "/bin/bash" {print $7}' /etc/passwd.
Python please. Design a Server Class that provides access to a SQLDatabase. The clients of your SQLDatabase server, send an SQLQuery to the SQLDatabase. The SQLDatabase processes the SQLQuery and returns the Data from the Query in a DataFrame. Your class should implement the default __dunders__ and potentially create some custom __dunders__.
