CONDITIONAL STRUCTURES (also known as selection structures or decision structures)

keywords : if, elif, else

1. Single alternative example:
Syntax:
    if condition:
        statement(s)
"""

# Write a program that prints a warning message if the temperature is greater
# than 30 degrees Celsius.
temperature = int(input("Enter the temperature: "))
if temperature > 30:
    print("It's hot outside")
print("End of program")

"""
2. Dual alternative example:
Syntax:
    if condition:
        statement(s)
    else:
        statement(s)
"""
# Write a program that prints a warning message if the temperature is greater
# than 30 degrees Celsius, otherwise print a message that it's a nice day.
temperature = int(input("Enter the temperature: "))
if temperature > 30:

else:
