Pandas DataFrame is one of the most useful data structures in Python for organizing and analyzing data. It stores information in rows and columns, similar to an Excel spreadsheet or SQL table, making it easy to work with large datasets.
What is a Pandas DataFrame?
A DataFrame is a two-dimensional table where each column can store different types of data, such as numbers, text, or dates.

First, install and import Pandas.
pip install pandas
import pandas as pd
data = {
"Name": ["Alice", "Bob", "Charlie"],
"Age": [24, 28, 22]
}
df = pd.DataFrame(data)
print(df)

df["Name"]
Filter Data
df[df["Age"] > 23]
Add a New Column
df["City"] = ["Delhi", "Mumbai", "Jaipur"]

Pandas DataFrames are widely used for:
Data Analysis
Machine Learning
Business Reports
Financial Analysis
CSV and Excel Data Processing
