Getting Started with Pandas 2025

Installation & Setup:

bash CODE

pip install pandas

Creating a DataFrame:

Python CODE

import pandas as pd

data = {'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [25, 30, 35]}
df = pd.DataFrame(data)
print(df)

Reading Data from CSV:

Python CODE

df = pd.read_csv('data.csv')
print(df.head())

Data Cleaning:

Python CODE

df.dropna(inplace=True)  # Remove missing values
df.fillna(value=0, inplace=True)  # Replace missing values with 0

Filtering & Querying Data:

Python CODE

filtered_df = df[df['Age'] > 30]

Grouping and Aggregation:

Python CODE

grouped = df.groupby('Category').mean()

Merging & Joining Data:

Python CODE

df_merged = df1.merge(df2, on='ID')
