Simple Python Program: Adding Two Numbers

QUESTION

Question5: Use the interactive Python shell to write a Python program that:

1. Creates two variables x and y of type integer.
   1. Assign the value 4 to variable x.
   2. Assign the value 10 to variable y.
2. Adds the values in x and y and store the result in a variable named result.
3. Outputs (prints) the value stored in result (use the print statement)

ANSWER

Simple Python Program: Adding Two Numbers

Introduction

In this essay, we will walk through the steps to create a simple Python program using the interactive Python shell. The program will involve creating two integer variables, assigning values to them, adding those values together, and finally printing the result. This beginner-level Python program will demonstrate the basics of variable assignment, mathematical operations, and output in Python.

Step 1: Creating Variables

First, let’s open the Python interactive shell. We can do this by opening the command prompt (Windows) or terminal (macOS/Linux) and typing ‘python’ or ‘python3’ depending on your Python version. Once the Python shell is open, we can proceed to create our variables.

Step 2: Assigning Values to Variables

We will create two integer variables, ‘x’ and ‘y’, and assign values to them. For this example, we will assign 4 to ‘x’ and 10 to ‘y’.

“`python
x = 4
y = 10
“`

Step 3: Performing Addition

Next, we’ll add the values in ‘x’ and ‘y’ together and store the result in a new variable called ‘result’. Python allows us to perform arithmetic operations with ease, and the ‘+’ operator will be used for addition.

“`python
result = x + y
“`

Step 4: Outputting the Result

Finally, we’ll print the value stored in the ‘result’ variable. The ‘print’ statement is used to display information to the user.

“`python
print(result)
“`

Conclusion

In this essay, we created a simple Python program that involved creating two integer variables, ‘x’ and ‘y’, assigning values to them, adding those values together, and printing the result. By executing each step in the Python interactive shell, we were able to see the output immediately. This example showcases the fundamental aspects of Python programming, such as variable assignment, arithmetic operations, and printing output. As you progress in your Python journey, you will encounter more complex programs and utilize various programming concepts to solve real-world problems. Happy coding!
