What"s the difference between `raw_input()` and `input()` in Python 3?
Raw Input vs Input: Demystifying Python 3
Are you a budding Python developer or an aspiring coder looking to master the basics of Python 3? One question that often confuses beginners is the difference between raw_input() and input() in Python 3. 🤔
Fear not, my friends! In this blog post, we will decode this mystery and provide you with a clear understanding of these two functions, along with easy solutions to common problems that you may encounter. Let's dive right in! 💪
Understanding the Basics
Python 3 introduces a change in function names compared to its predecessor, Python 2. In Python 2, there is a function called raw_input() which is used to read user input from the command line. However, in Python 3, this function has been renamed to input(). So, technically speaking, raw_input() does not exist in Python 3. 🚫
The Distinction
In Python 3, input() serves the purpose of both raw_input() and input() from Python 2. It reads user input as a string and returns it. This means that regardless of whether you use input() or raw_input() in Python 3, you will always get a string as the result. 🔄
A Common Confusion
One of the common mistakes beginners make while using input() is treating the input as an integer when they actually need one. Let's say we want to ask the user for their age and perform some arithmetic operations on it. Here's an example:
age = input("Enter your age: ")In this case, age will be assigned a string value, not an integer. So if you try to do something like age + 5, you will encounter an error because you're trying to concatenate a string with an integer. 😱
The Solution
To convert the input from a string to an integer, we need to use the int() function. Here's an updated code snippet to handle this:
age = int(input("Enter your age: "))By using int() to convert the input to an integer, you can now perform arithmetic operations with ease. 🎉
Encouraging Your Pythonic Journey
Now that you have a clear understanding of the difference between raw_input() and input() in Python 3, it's time for you to put it into practice. Try writing your own code snippets and experiment with different scenarios. Learning to code is all about hands-on experience! 💻
