✅ Python Control Flow Part 1: if, elif, else 🧠💻

What is Control Flow?
👉 Your code makes decisions
👉 Runs only when conditions are met

• Each condition is True or False
• Python checks from top to bottom

🔹 Basic if statement

age = 20  
if age >= 18:  
    print("You are eligible to vote")

▶️ Checks if age is 18 or more. Prints "You are eligible to vote"

🔹 if-else example

age = 16  
if age >= 18:  
    print("Eligible to vote")  
else:  
    print("Not eligible")

▶️ Age is 16, so it prints "Not eligible"

🔹 elif for multiple conditions

marks = 72  
if marks >= 90:  
    print("Grade A")  
elif marks >= 75:  
    print("Grade B")  
elif marks >= 60:  
    print("Grade C")  
else:  
    print("Fail")

▶️ Marks = 72, so it matches >= 60 and prints "Grade C"

🔹 Comparison Operators

a = 10  
b = 20  
if a != b:  
    print("Values are different")

▶️ Since 10 ≠ 20, it prints "Values are different"

🔹 Logical Operators

age = 25  
has_id = True  
if age >= 18 and has_id:  
    print("Entry allowed")

▶️ Both conditions are True → prints "Entry allowed"

⚠️ Common Mistakes:
• Using = instead of ==
• Bad indentation
• Comparing incompatible data types

📌 Mini Project – Age Category Checker

age = int(input("Enter age: "))  

if age < 13:  
    print("Child")  
elif age <= 19:  
    print("Teen")  
else:  
    print("Adult")

▶️ Takes age as input and prints the category


📝 Practice Tasks:
1. Check if a number is even or odd
2. Check if number is +ve, -ve, or 0
3. Print the larger of two numbers
4. Check if a year is leap year

✅ Practice Task Solutions – Try it yourself first 👇

1️⃣ Check if a number is even or odd

num = int(input("Enter a number: "))
if num % 2 == 0:
    print("Even number")
else:
    print("Odd number")

▶️ % gives remainder. If remainder is 0, it's even.


2️⃣ Check if number is positive, negative, or zero

num = float(input("Enter a number: "))
if num > 0:
    print("Positive number")
elif num < 0:
    print("Negative number")
else:
    print("Zero")

▶️ Uses > and < to check sign of number.


3️⃣ Print the larger of two numbers

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

if a > b:
    print("Larger number is:", a)
elif b > a:
    print("Larger number is:", b)
else:
    print("Both are equal")

▶️ Compares a and b and prints the larger one.


4️⃣ Check if a year is leap year

year = int(input("Enter a year: "))
if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0):
    print("Leap year")
else:
    print("Not a leap year")

▶️ Follows leap year rules:
- Divisible by 4 ✅
- But not divisible by 100 ❌
- Unless also divisible by 400 ✅


📅 Daily Rule:
✅ Code 60 mins
✅ Run every example
✅ Change inputs and observe output

✅ SQL for Data Analytics 📊🧠

Mastering SQL is essential for analyzing, filtering, and summarizing large datasets. Here's a quick guide with real-world use cases:

1️⃣ SELECT, WHERE, AND, OR
Filter specific rows from your data.

SELECT name, age  
FROM employees  
WHERE department = 'Sales' AND age > 30;

2️⃣ ORDER BY & LIMIT
Sort and limit your results.

SELECT name, salary  
FROM employees  
ORDER BY salary DESC  
LIMIT 5;

▶️ Top 5 highest salaries

3️⃣ GROUP BY + Aggregates (SUM, AVG, COUNT)
Summarize data by groups.

SELECT department, AVG(salary) AS avg_salary  
FROM employees  
GROUP BY department;

4️⃣ HAVING
Filter grouped data (use after GROUP BY).

SELECT department, COUNT(*) AS emp_count  
FROM employees  
GROUP BY department  
HAVING emp_count > 10;

5️⃣ JOINs
Combine data from multiple tables.

SELECT e.name, d.name AS dept_name  
FROM employees e  
JOIN departments d ON e.dept_id = d.id;

6️⃣ CASE Statements
Create conditional logic inside queries.

SELECT name,  
  CASE  
    WHEN salary > 70000 THEN 'High'  
    WHEN salary > 40000 THEN 'Medium'  
    ELSE 'Low'  
  END AS salary_band  
FROM employees;

7️⃣ DATE Functions
Analyze trends over time.

SELECT MONTH(join_date) AS join_month, COUNT(*)  
FROM employees  
GROUP BY join_month;

8️⃣ Subqueries
Nested queries for advanced filters.

SELECT name, salary  
FROM employees  
WHERE salary > (SELECT AVG(salary) FROM employees);

9️⃣ Window Functions (Advanced)

SELECT name, department, salary,  
       RANK() OVER(PARTITION BY department ORDER BY salary DESC) AS dept_rank  
FROM employees;

▶️ Rank employees within each department

💡 Used In:
• Marketing: campaign ROI, customer segments
• Sales: top performers, revenue by region
• HR: attrition trends, headcount by dept
• Finance: profit margins, cost control
