✅ Python Basics for Data Analytics 📊🐍

Python is one of the most in-demand languages for data analytics due to its simplicity, flexibility, and powerful libraries. Here's a detailed guide to get you started with the basics:

🧠 1. Variables Data Types
You use variables to store data.

name = "Alice"        # String  
age = 28              # Integer  
height = 5.6          # Float  
is_active = True      # Boolean

Use Case: Store user details, flags, or calculated values.

🔄 2. Data Structures

✅ List – Ordered, changeable

fruits = ['apple', 'banana', 'mango']  
print(fruits[0])  # apple

✅ Dictionary – Key-value pairs

person = {'name': 'Alice', 'age': 28}  
print(person['name'])  # Alice

✅ Tuple Set
Tuples = immutable, Sets = unordered unique

⚙️ 3. Conditional Statements

score = 85  
if score >= 90:  
    print("Excellent")  
elif score >= 75:  
    print("Good")  
else:  
    print("Needs improvement")

Use Case: Decision making in data pipelines

🔁 4. Loops
For loop

for fruit in fruits:  
    print(fruit)

While loop

count = 0  
while count < 3:  
    print("Hello")  
    count += 1

🔣 5. Functions
Reusable blocks of logic

def add(x, y):  
    return x + y  

print(add(10, 5))  # 15

📂 6. File Handling
Read/write data files

with open('data.txt', 'r') as file:  
    content = file.read()  
    print(content)

🧰 7. Importing Libraries

import pandas as pd  
import numpy as np  
import matplotlib.pyplot as plt

Use Case: These libraries supercharge Python for analytics.

🧹 8. Real Example: Analyzing Data

import pandas as pd  

df = pd.read_csv('sales.csv')  # Load data  
print(df.head())               # Preview  

# Basic stats  
print(df.describe())  
print(df['Revenue'].mean())
