## What is Python?

Before we dive into the details of adding two numbers in Python, let’s first talk about what Python is. Python is a high-level, interpreted programming language that was first released in 1991. It was designed to be easy to learn, read, and write, which makes it a popular choice for beginners.

Python is also known for its readability and clean syntax, which means that it’s easy to read and understand even if you don’t have much programming experience. The language is also versatile and can be used for a wide range of applications, including web development, scientific computing, data analysis, and more.

## Variables in Python

Before we can add two numbers in Python, we first need to understand variables. In programming, variables are used to store values that can be used later in the program. In Python, variables are created by assigning a value to a name.

For example, we can create a variable called "x" and assign it the value of 5 by typing:

`x = 5`

Now the variable "x" contains the value of 5. We can also create a variable called "y" and assign it the value of 10 by typing:

`y = 10`

Now we have two variables, "x" and "y", each with a different value.

## Adding Two Numbers in Python

Now that we understand variables, let’s move on to adding two numbers in Python. To add two numbers in Python, we simply use the "+" operator.

For example, let’s say we want to add the values of "x" and "y" together. We can do this by typing:

`z = x + y`

Now the variable "z" contains the value of 15, which is the sum of "x" and "y".

We can also add two numbers together without using variables. For example, if we want to add the values of 5 and 10 together, we can simply type:

`z = 5 + 10`

Now the variable "z" contains the value of 15.

## Data Types in Python

Before we move on to more advanced topics, let’s talk about data types in Python. In programming, data types are used to define the type of data that can be stored in a variable. Python has several built-in data types, including:

- Numbers (integers, floats, and complex numbers)
- Strings
- Booleans
- Lists
- Tuples
- Sets
- Dictionaries

For the purposes of adding two numbers in Python, we’ll focus on the "int" data type, which is used to represent integers (whole numbers).

## User Input in Python

So far, we’ve been assigning values to variables directly in our code. However, in many cases, we want the user to input values that we can then use in our program. In Python, we can use the "input" function to prompt the user for input.

For example, if we want the user to input two numbers that we can then add together, we can use the following code:

```
x = int(input("Enter the first number: "))
y = int(input("Enter the second number: "))
z = x + y
print("The sum of", x, "and", y, "is", z)
```

When this code is run, the user will be prompted to enter two numbers. These numbers will be stored in the variables "x" and "y", respectively. We then use the "+" operator to add these numbers together and store the result in the variable "z". Finally, we use the "print" function to output the result to the user.

## Conclusion

In this comprehensive guide, we’ve covered the basics of adding two numbers in Python. We started by discussing what Python is and how variables work. We then walked through the process of adding two numbers together using the "+" operator.

We also talked about data types in Python and how to use the "input" function to prompt the user for input. By following these steps, you should now be able to add two numbers together in Python with ease.

Remember, programming takes practice, so don’t be discouraged if you don’t get it right away. Keep practicing, and soon you’ll be adding not just two, but any number of numbers together in Python!
