What is Python 2?

The Python Enhancement Proposal (PEP), a brand-new technical standard included with Python 2, was designed to offer recommendations and best practices for producing Python code. Along with these new capabilities, it also has a garbage collector that detects cycles and supports Unicode and list comprehension.

However, the creation process itself was the biggest alteration in Python 2. Python was made to be a fresher-friendly programming language. The Python manufacturing t team, led by Guido von Rossum, chose to switch to a more open and community-supported development method to fulfill this target.

Over time, Python 2 saw more development. New features were introduced to the programming syntax in later editions.

What is Python 3?

The next in the queue of the programming language is called Python 3. December 2008 saw its availability, which composed several enhancements and new advancements.

After debugging, Python 3 was more than simply a rewritten version of Python 2 code. The language was significantly altered in the latest edition to fix security holes and poor design in earlier iterations. A new syntax introduced in Python 3 is meant to avoid writing redundant or repetitive code—that is, code that performs the same operation in several ways. Python 3 has significantly improved in terms of readability and convenience of use by offering a single, unambiguous method of doing tasks.  

Python 3 has made some significant modifications, such as converting the print statement to an integrated function, enhancing integer division, and enhancing Unicode support.

Can you Convert Python 2 to 3?

It is believed it would be prudent to discuss what could be involved when you encounter code written in Python 2 before wrapping off the Python 3 basics series. This is because you will likely see it frequently and it is a fundamental aspect of learning Python 3.

In general, the Python 2 print statement is more likely to be the main cause of the Python 2 code not functioning in Python 3 than the Python 3 print function.

copy “Hello, the above works well with Python 2 but fails with Python 3 due to a syntax issue. Nevertheless, Python 2 code can also be

print(“Hello there”)

The majority of Python 3 code can be executed on Python 2.

The way that individuals handle exceptions will be another significant distinction.

Although the code above is intended to be used for writing exceptions in Python 3, it also functions as intended in Python 2.

The use of urllib and universal internet access is the third significant distinction I see between Python 2 and Python 3 code.

Python 2 returns string data when it comes to internet information. It is input as bytes in Python 3 and needs to be treated as such, even if you want to interpret it like a string.

These are the primary regions; there are a good number of minor ones as well. Smaller scripts may typically have these issues resolved quite quickly. But for bigger ones, it might get quite boring, very quickly. Python 3 has a tool called 2to3 that can change a good amount of the frequent changes between code written in Python 2 and Python 3.


Python 2 vs. Python 3: What’s the Difference?

Python 2 and 3, two of the well-known and widely used coding languages, have contributed to increment in a variety of fields, comprised of data science, software engineering, and artificial intelligence. Both of them are highly efficient and have a wide range of uses. Many people are confused about whether they ought to get the most recent version or not.

Let’s analyze the key parity between Python 2 and 3 after going over some of the basic advantages of adopting each version.

Keeping Strings Stored

The use of Unicode for all functions in Python 3 contrary to ASCII encoding in Python 2 is one of the biggest differences between the two languages. When code intended for one version is accomplished on another, this discrepancy may result in certain issues.

Annotations Type annotations are supported in Python 3, which is another distinction. When announcing a variable, you may clear its type by using type annotations. This can improve the maintainability and simplification of the code. Type annotations are not worked by Python 2.

Managing Exceptions

Additionally, Python 3 offers certain enhancements to exception handling. Python 2 handles exceptions by looking for the particular type of exception. Python 3 handles exceptions by matching the exception’s value. It is now simpler to handle unexpected exceptions in your code thanks to this modification.

Statement in Print

Some features that were considered obsolete in Python 2 were changed in Python 3. The ‘print’ statement is one such instance. Python 3 requires the usage of brackets; in Python 2, the print command can be used without them.

Syntax Python 3 also brought about a few changes to the language. As we just saw, the ‘print’ statement is one example. The ‘range’ and ‘next’ functions are two more examples.

Python 2 vs. Python 3: Which Is the Best to Learn?

Normally speaking, unless your employment providers still using Python 2, it makes more sense to study Python 3. Python 2 was made public on April 20, 2020; the most new version of the language is available with Python 3.
