Q2]
A]
import pandas as pd

1. Creating a dataframe with columns name, age, and percentage

data = {'name': ['John', 'Jane', 'Bob', 'Alice', 'Charlie', 'David', 'Eva', 'Frank', 'Grace', 'Henry'],
'age': [25, 22, 30, 28, 35, 40, 26, 32, 29, 27],
'percentage': [80.5, 75.2, 92.0, 88.5, 78.9, 95.3, 81.7, 89.6, 93.2, 87.4]}

df = pd.DataFrame(data)

2. Printing information about the dataframe

print("DataFrame:")
print(df)

print("\nDataFrame Information:")
print("Shape:", df.shape)
print("Number of Rows-Columns:", df.shape[0], "-", df.shape[1])
print("Data Types:")
print(df.dtypes)
print("Feature Names:")
print(df.columns)
print("Description:")
print(df.describe())

3. Adding 5 rows with duplicate values and missing values

df = pd.concat([df, df.head(5)], ignore_index=True)

Adding a column 'remarks' with empty values

df['remarks'] = ""

Displaying the updated data

print("\nUpdated DataFrame:")
print(df)
