How to add two numbers in Python

How to add two numbers in Python.

Here is a step-by-step tutorial on how to add two numbers in Python using different code examples:

Open your preferred Python Integrated Development Environment (IDE) or text editor and create a new Python file.
Start by declaring two variables to store the numbers you want to add. For example, let's say we want to add the numbers 5 and 3. We can declare the variables as follows:

num1 = 5
num2 = 3

Now, you have two options to add these numbers:
a. Using the + operator:
You can simply use the + operator to add the values of the two variables. Assign the result to a new variable or print it directly. Here's an example:
```
result = num1 + num2
print("The sum is:", result)
```
Output:
```
The sum is: 8
```
b. Using the sum() function:
Python provides a built-in function called sum() to add multiple numbers. You can pass the numbers as an iterable, such as a list or tuple. Here's an example:
```
result = sum([num1, num2])
print("The sum is:", result)
```
Output:
```
The sum is: 8
```
Another approach is to create a function that takes two arguments and returns the sum. This way, you can reuse the code whenever you need to add two numbers. Here's an example:

def add_numbers(a, b):
    return a + b

result = add_numbers(num1, num2)
print("The sum is:", result)

Output:

The sum is: 8

If you want to add numbers entered by the user, you can use the input() function to get the input as strings and then convert them to integers. Here's an example:

num1 = int(input("Enter the first number: "))
num2 = int(input("Enter the second number: "))

result = num1 + num2
print("The sum is:", result)

Output:

Enter the first number: 5
Enter the second number: 3
The sum is: 8

That's it! You now know different ways to add two numbers in Python. Feel free to choose the method that suits your needs best.
