| 3 | ✅ 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())
🎯 Why Learn Python for Data Analytics?
✅ Easy to learn
✅ Huge library support (Pandas, NumPy, Matplotlib)
✅ Ideal for cleaning, exploring, and visualizing data
✅ Works well with SQL, Excel, APIs, and BI tools

| 5 | 🔥 Pandas Scenario-Based Interview Question 🐼
📊 Scenario:
You have an orders dataset with:
order_id
customer_id
order_date
category
sales
🎯 Task:
Find the top-selling category for each month based on total sales.
✅ Pandas Solution:
import pandas as pd
# Convert to datetime
df['order_date'] = pd.to_datetime(df['order_date'])
# Extract month
df['month'] = df['order_date'].dt.strftime('%b-%Y')
# Total sales by month & category
sales_summary = (
df.groupby(['month', 'category'])['sales']
.sum()
.reset_index()
)
# Rank categories within each month
sales_summary['rank'] = (
sales_summary.groupby('month')['sales']
.rank(method='dense', ascending=False)
)
# Top category per month
result = sales_summary[sales_summary['rank'] == 1]
print(result)
💡 Concepts Tested:
✔️ groupby()
✔️ Date handling
✔️ Aggregation
✔️ Ranking within groups

| 6 | Excel Basics for Data Analytics
Excel sits at the start of most analysis work.
What you use Excel for
• Cleaning raw data
• Exploring patterns
• Quick summaries for teams
Core concepts you must know
• Data setup
– Freeze header row. View → Freeze Top Row.
– Convert range to table. Ctrl + T.
– Use proper headers. No merged cells. One value per cell.
• Data cleaning
– Remove duplicates. Data → Remove Duplicates.
– Trim extra spaces. =TRIM(A2)
– Convert text to numbers. =VALUE(A2)
– Fix date format. Format Cells → Date.
– Handle blanks. Filter blanks, fill or delete.
– Find and replace. Ctrl + H.
• Essential formulas
– Math and counts
▪ SUM. =SUM(A2:A100)

– Filters. Date, Region.
– Refresh after data update.
• Charts you must know
