2. Simple calci:[TBD]

num1 = float(input("Enter first number: "))
operator = input("Enter operator (+, -, *, /): ")
num2 = float(input("Enter second number: "))

if operator == "+":
    print("Result:", num1 + num2)
elif operator == "-":
    print("Result:", num1 - num2)
elif operator == "*":
    print("Result:", num1 * num2)
elif operator == "/":
    if num2 != 0:
        print("Result:", num1 / num2)
    else:
        print("Cannot divide by zero")
else:
    print("Invalid operator")

3. Find the Largest of Four Numbers:[TBD]

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
c = int(input("Enter third number: "))
d = int(input("Enter fourth number: "))

largest = a

if b > largest:
    largest = b

if c > largest:
    largest = c

if d > largest:
    largest = d

print("Largest number is:", largest)

4. ATM withdrawal:

balance = 10000

amount = int(input("Enter withdrawal amount: "))

if amount <= balance:
    balance = balance - amount
    print("Withdrawal Successful")
    print("Remaining Balance:", balance)
else:
    print("Insufficient Balance")

units = int(input("Enter electricity units: "))

if units <= 100:
    bill = units * 2
elif units <= 200:
    bill = (100 * 2) + ((units - 100) * 3)
else:
    bill = (100 * 2) + (100 * 3) + ((units - 200) * 5)

print("Electricity Bill = ₹", bill)

Hard level:

1. Banking loan:[TBD]
For can use if-else step by step

age = int(input("Enter your age: "))
salary = int(input("Enter your monthly salary: "))
credit_score = int(input("Enter your credit score: "))

if age >= 21:
    if salary >= 25000:
        if credit_score >= 700:
            print("Loan Approved")
        else:
            print("Loan Rejected: Low Credit Score")
    else:
        print("Loan Rejected: Salary Too Low")
else:
    print("Loan Rejected: Age Below 21")

2. Scholarship Eligibility:

marks = int(input("Enter marks: "))
income = int(input("Enter family income: "))

if marks >= 90 and income < 300000:
    print("Scholarship Approved")
else:
    print("Scholarship Not Approved")

total = int(input("Total classes: "))
attended = int(input("Classes attended: "))

attendance = (attended / total) * 100
