Converting Data Types with Confidence: Crafting a Python Function to Handle Integers, Floats, and Strings
Introduction
In this tutorial, we’ll explore a Python programming problem that involves writing a function to convert various data types to their corresponding integer or floating-point number representation. The function will accept int, float, and str inputs and return the appropriate number, while providing custom error messages for invalid inputs.
By the end of this post, you’ll have a better understanding of how to work with different data types, handle edge cases, and create custom error messages in Python.
Step 1: Defining the Function
First, let’s define a function called num
that takes a single argument, ip
, which is the input value:
def num(ip):
# Convert the input to the corresponding number
Step 2: Checking the Input Data Type
Inside the function, we’ll check the data type of the input ip
using the isinstance()
function. This function takes two arguments: the value to be checked and the data type to be compared against. We’ll use it to determine if the input is an int…
