 DAY 2 PYTHON NOTES

✅ Day 2: Operators, Conditionals, and Loops 👈

1️⃣ Operators in Python

➤ Arithmetic Operators

python
a = 10
b = 3

print(a + b)  # Addition
print(a - b)  # Subtraction
print(a * b)  # Multiplication
print(a / b)  # Division (float)
print(a // b) # Floor Division
print(a % b)  # Modulus
print(a ** b) # Exponent

➤ Comparison Operators (returns True/False)

python
a = 5
b = 3

print(a > b)   # Greater than
print(a < b)   # Less than
print(a == b)  # Equal to
print(a != b)  # Not equal
print(a >= b)  # Greater or equal
print(a <= b)  # Less or equal

➤ Logical Operators

python
x = 10
print(x > 5 and x < 20)  # True
print(x > 5 or x < 5)    # True
print(not(x > 5))        # False

2️⃣ Conditional Statements

➤ if, elif, else

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

if age >= 18:
    print("You are eligible to vote.")
elif age > 0:
    print("You are underaged.")
else:
    print("Invalid age.")

3️⃣ Loops in Python

➤ while Loop

python
i = 1
while i <= 5:
    print("Hello", i)
    i += 1

➤ for Loop (with range)

python
for i in range(1, 6):
    print("Number:", i)

➤ Loop with List

python
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)

➤ break and continue

python
for i in range(1, 6):
    if i == 3:
        break
    print(i)

for i in range(1, 6):
    if i == 3:
        continue
    print(i)
     
                                                                              BY-ABHI TECH
