<h1>Introduction to Python 3 vs Python 2 🐍🆚</h1>
|
|
<p><strong>Overview</strong><br>
|
|
Python 2 was released in 2000, Python 3 in 2008.<br>
|
|
Python 3 is not backward compatible with Python 2.<br>
|
|
As of January 1, 2020, Python 2 has been officially retired.</p>

<h1>Print Function 🖨️</h1>
|
|
<p><strong>Python 2</strong><br>
|
|
<code>print "Hello, world!"</code><br>
|
|
<strong>Python 3</strong><br>
|
|
<code>print("Hello, world!")</code><br>
|
|
<strong>Key Difference</strong><br>
|
|
Python 3 requires parentheses.</p>

|
|
<h1>Integer Division 🧮</h1>
|
|
<p><strong>Python 2</strong><br>
|
|
<code>3 / 2</code> equals <code>1</code><br>
|
|
<strong>Python 3</strong><br>
|
|
<code>3 / 2</code> equals <code>1.5</code><br>
|
|
<strong>Key Difference</strong><br>
|
|
Python 3 performs true division by default.</p>

|
<h1>Unicode Support 🌍</h1>
|
|
<p><strong>Python 2</strong><br>
|
|
Strings are ASCII by default.<br>
|
|
Unicode string with <code>u"Hello"</code><br>
|
|
<strong>Python 3</strong><br>
|
|
Strings are Unicode by default.<br>
|
|
<strong>Key Difference</strong><br>
|
|
Enhanced Unicode support in Python 3.</p>

|
|
<h1>Input Function 📥</h1>
|
|
<p><strong>Python 2</strong><br>
|
|
<code>raw_input()</code> for user input as string.<br>
|
|
<code>input()</code> evaluates the input as Python code.<br>
|
|
<strong>Python 3</strong><br>
|
|
<code>input()</code> for user input, always returns the input as a string.<br>
|
|
<strong>Key Difference</strong><br>
|
|
<code>input()</code> in Python 3 does not evaluate the input.</p>

<h1>Libraries and Packages 📚</h1>
|
|
<p><strong>Both Versions</strong><br>
|
|
Wide range of libraries and packages.<br>
|
|
<strong>Python 3</strong><br>
|
|
More libraries are now Python 3 compatible.<br>
|
|
Focus on Python 3 for future development.<br>
|
|
<strong>Key Point</strong><br>
|
|
Transition to Python 3 for better library support.</p>

<h1>Conclusion 🏁</h1>
|
|
<p><strong>Transition to Python 3</strong><br>
|
|
Strongly recommended for new projects.<br>
|
|
Active development, better library compatibility.<br>
|
|
<strong>Legacy Python 2 Code</strong><br>
|
|
Consider porting to Python 3 for long-term maintenance.</p>
