Common Arithmetic Operators Ocr

Python code

# -----------------------------------------------------------------------
# Arithmetic operators #1
# -----------------------------------------------------------------------
# Get the user to input a number
user_input = int(input("Enter a number: "))

# if the remainder of the number divided by 2 is 0, the number is even
if user_input % 2 == 0:
print("The number is even.")
else:
print("The number is odd.")

# -----------------------------------------------------------------------
# Arithmetic operators #2
# -----------------------------------------------------------------------
# Get the radius from the user
radius = float(input("Enter the radius of the circle: "))

# Calculate the area of the circle
area = 3.14159 * radius ** 2

# Display the calculated area
print("The area of the circle with radius",radius,"is",area)

# Set the score to 0
