How to Add a Number to an Integer in Python?

To add a number to an integer in Python, you simply use the + operator.

Here's a breakdown with examples:

Basic Addition

The most straightforward way to add a number (integer or float) to an integer is using the + operator.

a = 5   # An integer
b = 10  # Another integer
result = a + b
print(result)  # Output: 15

c = 5
d = 2.5 # A float
result = c + d
print(result)  # Output: 7.5

Explanation:

• We first assign the integer values to variables a, b and c. We also assigned a float value to d.
• Then, we use the + operator to add a and b (or c and d) together.
• The result of the addition is stored in the result variable.
• Finally, print(result) displays the sum.

Data Type Considerations:

• If you add two integers, the result will be an integer.
• If you add an integer and a float, the result will be a float. Python automatically performs type coercion to ensure the operation is valid.

Adding to an Existing Variable:

You can also add a number directly to an existing variable using the += operator.

x = 5
x += 3  # Equivalent to x = x + 3
print(x)  # Output: 8

In Summary:

Adding a number to an integer in Python is easily done with the + operator. Be mindful of the data types involved, as adding an integer and a float will result in a float.
