Write a Python function to add two numbers as input arguments
Adding two numbers in Python is a very simple task. We can use the + operator to add two numbers together. For example, the following code adds the numbers 1 and 2 and prints the result:
num1 = 1
num2 = 2
sum = num1 + num2
print(sum)
Output:
3
However, what if we want to write a Python function that adds two numbers together? This would allow us to reuse the code to add any two numbers together, without having to write the code again.
To write a Python function to add two numbers together, we can follow these steps:
- Define a function called
add_two_numbers()that takes two numbers as input and returns the sum of the two numbers. - Add the two numbers together and return the result.
Here is a Python function to add two numbers together:
def add_two_numbers(num1, num2):
"""Adds two numbers together.
Args:
num1: The first number to add.
num2: The second number to add.
Returns:
The sum of num1 and num2.
"""
sum = num1 + num2
return sum
# Example usage:
print(add_two_numbers(1, 2))
print(add_two_numbers(3.14, 5.92))
print(add_two_numbers("1", "2"))
Output:
3
9.06
12
The function add_two_numbers() can be used to add any two numbers together, regardless of their type. For example, we can use the function to add two integers, two floats, or two strings.
Benefits of using a Python function to add two numbers
There are several benefits to using a Python function to add two numbers:
- Reusability: Once you have written the function, you can reuse it to add any two numbers together, without having to write the code again.
- Readability: The function makes the code more readable and easier to maintain.
- Testability: The function can be easily tested to ensure that it is working correctly.
Conclusion
Writing a Python function to add two numbers is a simple task, but it has several benefits. The function can be reused, is more readable, and easier to test.
