📚 Python Libraries for Beginners

📚 What are Python Libraries?

Python libraries are collections of pre-written code that provide useful functions and tools. They help developers build applications faster and easier.

✨ Why Use Python Libraries?

• Reduce coding time
• Provide ready-made solutions
• Improve productivity
• Used in real-world applications

⚙️ Installing Python Libraries

Libraries can be installed using the pip command.

pip install library_name

🔢 NumPy Library

NumPy is used for numerical calculations and working with arrays. It is popular in data science and machine learning.

import numpy as np

numbers = np.array([1,2,3,4])

print(numbers)

🐼 Pandas Library

Pandas is used for data analysis and handling data in tables.

import pandas as pd

data = {
"name":["Roshni","Amit"],
"age":[18,20]
}

df = pd.DataFrame(data)

print(df)

📊 Matplotlib Library

Matplotlib is used to create graphs and data visualizations.

import matplotlib.pyplot as plt

x=[1,2,3]
y=[4,5,6]

plt.plot(x,y)

plt.show()

🌐 Requests Library

Requests library is used to send HTTP requests and work with APIs.

import requests

response = requests.get(
"https://example.com"
)

print(response.status_code)

🤖 TensorFlow Library

TensorFlow is a popular library used for Artificial Intelligence and Machine Learning.

• Image recognition
• Deep learning models
• Neural networks
