# Input two numbers
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))

# Calculate the sum
result = num1 + num2

# Display the result
print("The sum of", num1, "and", num2, "is:", result)

This is a simple calculation code using python, and now I am goind to expanded it.

print("Welcome to calculate web!")
#This is a hello sentence
