 Hello and welcome back to my new blog. In this blog, I am going to share with you the code of the video insert, update, delete, and retrieve so to access the code please do read the full blog.

                                                                                


Insert Code with Explanation in Detail👇

In this Python MongoDB tutorial, you'll learn how to use the PyMongo library to connect to a MongoDB database and insert employee data into it. We'll walk you through the process step by step, explaining each part of the code along the way.

from pymongo import MongoClient

# Connect to the MongoDB server running on localhost at port 27017

Client = MongoClient("localhost:27017")


# Access the 'EmployeeData' database

db = Client.EmployeeData


# Define a function to insert employee data into the 'Employees' collection

def insert():

    try:

        # Prompt the user for employee details

        employeeID = input("Enter employee id: ")

        employeeName = input("Enter name: ")

        employeeAge = input("Enter age: ")

        employeeCountry = input("Enter country: ")


        # Insert the employee data into the 'Employees' collection

        db.Employees.insert_one(

            {

                "id": employeeID,

                "name": employeeName,

                "age": employeeAge,

                "country": employeeCountry

            })

        

        print("\nInserted successfully\n")

    

    except Exception as e:

        print(str(e))


# Call the insert function to insert employee data

insert()

                                                                                    



Update Code with Explanation in Detail👇

In this Python MongoDB tutorial, we'll guide you through the process of updating employee data in a MongoDB database using the PyMongo library. Watch this video to learn how to connect to your MongoDB server, access a specific database, and update employee records with ease.

from pymongo import MongoClient

# Connect to the MongoDB server running on localhost at port 27017
Client = MongoClient("localhost:27017")

# Access the 'EmployeeData' database
db = Client.EmployeeData

# Define a function to update employee data in the 'Employees' collection
def update():
    try:
        # Prompt the user for the employee name and new age
        name = input("Enter employee name that you want to update: ")
        age = input("Enter employee age that you want to update: ")

        # Use the update_many method to update matching records
        db.Employees.update_many({"name": name}, {"$set": {"age": age}})
        
        print("Updated successfully")
    
    except Exception as e:
        print(str(e))

# Call the update function to update employee data
update()
