*Week - I Programs*
1) Write a program to find the largest element among three Numbers
CODE:
Method 1: Using if-else statements
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
c = int(input("Enter third number: "))
if a >= b and a >= c:
largest = a
elif b >= a and b >= c:
largest = b
else:
largest = c
print("The largest number is:", largest)
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------
Method 2: Using max() function
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
c = int(input("Enter third number: "))
largest = max(a, b, c)
print("The largest number is:", largest)
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------
Method 3: Using Ternary operator
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
c = int(input("Enter third number: "))
largest = a if (a > b and a > c) else (b if b > c else c)
print("The largest number is:", largest)

c = int(input("Enter third number: "))
numbers = [a, b, c]
largest = sorted(numbers)[-1]
print("The largest number is:", largest)

for num in range(start, end + 1):
if num > 1:
for i in range(2, num):
if num % i == 0:
break
else:
print(num, end=" ")

is_prime = True
for i in range(2, int(math.sqrt(num)) + 1):
if num % i == 0:
is_prime = False
break

if n % i == 0:
return False
return True
start = int(input("Enter the start of interval: "))
end = int(input("Enter the end of interval: "))
print(f"Prime numbers between {start} and {end} are:")
for num in range(start, end + 1):
if is_prime(num):
print(num, end=" ")

3) Write a program to swap two numbers without using a temporary variable.
CODE:
Method 1: Addition and Subtraction
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
a = a + b
b = a - b
a = a - b
print("After swapping: a =", a, ", b =", b)
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------
Method 2: Multiplication and Division
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
a = a * b
b = a / b
a = a / b
print("After swapping: a =", int(a), ", b =", int(b))
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------
Method 3: Pythonic way (Tuple unpacking)
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
a, b = b, a
print("After swapping: a =", a, ", b =", b)
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------

print("a + b =", a + b) # Addition
print("a - b =", a - b) # Subtraction
print("a * b =", a * b) # Multiplication

print()
8. Identity Operators
x = [1, 2, 3]
y = [1, 2, 3]
z = x
print("Identity Operators:")
print("x is y →", x is y) # False (different objects with same content)

print("Addition:", a + b)
print("Multiplication:", a * b)
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------

print("Addition:", a + b)
print("Multiplication:", a * b)

6) Write a program to print multiplication table of a given number.
CODE:

num = int(input("Enter a number: "))
print(f"Multiplication Table of {num}")
for i in range(1, 11):
print(f"{num} x {i} = {num * i}")
OUTPUT: ----------------------------- Try on your ownđź‘Ź-----------------------------
Method 2: While loop
num = int(input("Enter a number: "))
print(f"Multiplication Table of {num}")
i = 1
while i <= 10:
print(f"{num} x {i} = {num * i}")
i += 1
