Wrapping Up Python's Modulo, Logical Operators, and Assignments 🎉

As we conclude our exploration of Python's operators, let’s revisit the essential concepts and their real-world applications. Mastering these foundational tools empowers you to build robust and efficient systems.

🔢 The Modulo Operator (%)

The Modulo operator is a powerful tool for evaluating the remainder of a division. Its use is particularly prominent in systems requiring divisibility checks, such as ATM withdrawal logic.

Example: Checking Divisibility for Denominations

amount = 1500

if amount % 500 == 0:
    print("Withdrawable with ₹500 notes")
elif amount % 200 == 0:
    print("Withdrawable with ₹200 notes")
else:
    print("Amount cannot be withdrawn with available denominations")

Key Takeaway:

The Modulo operator helps ensure that requested amounts align with available note denominations. If the remainder is 0, the amount is valid for withdrawal.

🔗 Logical Operators: AND, OR, and NOT

Logical operators extend the functionality of conditional statements, enabling more complex decision-making.

AND (and)

Ensures all conditions are True.

OR (or)

Requires at least one condition to be True.

NOT (not)

Inverts the result of a condition:

• True becomes False.

• False becomes True.

Example: Combining Multiple Conditions

if (amount % 500 == 0 or amount % 200 == 0) and amount <= atm_balance:
    print("Amount is withdrawable")
else:
    print("Amount exceeds balance or is not divisible by available notes")

Key Points:

• OR: Ensures divisibility by either ₹500 or ₹200.

• AND: Confirms the requested amount does not exceed the ATM’s balance.

---

🖊 Assignment Operators

Assignment operators simplify arithmetic operations while assigning values.

Examples:

Traditional Assignment:

a = a + 2

Using +=:

a += 2

Other Variations:

• -=: Subtract and assign.

• *=: Multiply and assign.

• /=: Divide and assign.

Why Use Them?

• Reduces redundancy.

• Makes code cleaner and more efficient.

🏧 Real-World Applications: ATM System Logic

We combined these concepts to create robust logic for handling ATM withdrawals, ensuring:

1. Requested amounts are divisible by ₹500 or ₹200.

2. The withdrawal does not exceed the ATM’s total balance.

Final Example: ATM System Logic

amount = 1200
atm_balance = 5000

if (amount % 500 == 0 or amount % 200 == 0) and amount <= atm_balance:
    print("Amount is withdrawable")
else:
    print("Amount exceeds balance or is not divisible by available notes")

🧩 Key Takeaways

1. The Modulo operator (%) is invaluable for divisibility checks in systems like ATMs.

2. Logical operators (AND, OR, NOT) enable complex conditional logic.

3. Assignment operators make arithmetic operations concise and efficient.

4. Combining these tools helps solve real-world problems with precision.
