The or Operator

# Define variables
a = 10
b = 20

# Using the or operator in an if statement
if a > 15 or b > 15:
    print("At least one condition is True")
else:
    print("Both conditions are False")

# Define variables
user_input = ""  # Empty string
default_value = "default"

# Using the or operator to provide a default value
value = user_input or default_value
print(value)  # Output: default

def first_condition():
    print("Evaluating first condition...")
    return True

def second_condition():
    print("Evaluating second condition...")
    return False

# Using the or operator with short-circuit evaluation
if first_condition() or second_condition():
    print("At least one condition is True")

# Define a list of numbers
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# Use list comprehension with the or operator
filtered_numbers = [num for num in numbers if num % 2 == 0 or num > 5]
print(filtered_numbers)  # Output: [2, 4, 6, 7, 8, 9, 10]

# Define variables
x = 5
y = 10
z = 15

# Using the or and and operators together
if (x < y and y < z) or (x > z):
    print("Complex condition is True")
else:
    print("Complex condition is False")

# Define variables
a = None
b = "Python"

# Using the or operator for a conditional assignment
result = a or b
print(result)  # Output: Python

def greet(name=None):
    # Provide a default value using the or operator
    name = name or "Guest"
    print(f"Hello, {name}")

# Example usage
greet("Alice")  # Output: Hello, Alice
greet()         # Output: Hello, Guest
