The Procedure of Mail Merge in MS Word
The procedure of Mail Merge in MS Word involves the following steps:
- Prepare the Main Document: Create the document you want to send, such as a letter, email, or label. Use placeholders for the variable data like names or addresses.
- Create or Select the Data Source: Use an existing data source (Excel spreadsheet, Word table, or Access database) or create a new one with the information you want to merge (e.g., recipient names, addresses).
- Link the Data Source:
- Go
Data Analysis Techniques in Python: Merging, Reshaping, and More
1) Import pandas as pd
import numpy as np
# Create two sample DataFrames
sales_data_1 = pd.DataFrame({
‘OrderID’: [1, 2, 3, 4],
‘Product’: [‘Laptop’, ‘Tablet’, ‘Smartphone’, ‘Headphones’],
‘Sales’: [100, 200, 2000, 800]
})
sales_data_2 = pd.DataFrame({
‘OrderID’: [3, 4, 5, 6],
‘Product’: [‘Headphones’, ‘Laptop’, ‘Smartwatch’, ‘Tablet’],
‘Sales’: [500, 300, 200, 900]
})
# Display the DataFrames
print(“Sales Data 1:\n”, sales_data_1)
print(“\nSales Data 2:\n”, sales_data_2)
Machine Learning: Key Concepts and Applications
What is Machine Learning?
Machine Learning (ML) is a subset of Artificial Intelligence (AI) that involves training models to learn from data and make decisions or predictions without explicit programming.
Key Elements of Machine Learning:
- Data: Raw information, including labeled or unlabeled datasets, used to train models.
- Model: A mathematical representation of a process or system.
- Algorithms: Procedures used to process data and learn from it.
- Training: The process of feeding data into the model to allow

Program 1: Data Manipulation with Pandas
This program demonstrates various data manipulation techniques using the Pandas library in Python.
Merging and Concatenating Data
import pandas as pd
import numpy as np
sales_data_1 = pd.DataFrame({
'OrderID': [1, 2, 3, 4],
'Product': ['Laptop', 'Tablet', 'Smartphone', 'Headphones'],
'Sales': [100, 200, 2000, 800]
})
sales_data_2 = pd.DataFrame({
'OrderID': [3, 4, 5, 6],
'Product': ['Headphones', 'Laptop', 'Smartwatch', 'Tablet'],

Implementing Menu-Driven Programs for Data Structures in C
1. Circular Singly Linked List Operations
Develop and implement a menu-driven program in C for the following operations on Circular Singly Linked List (CSLL):
- Insertion at front of SLL
- Deletion at end of SLL
- Display the status of SLL
- Exit
