Getting aware of the new versions of the languages is always beneficial as a developer. Compare Python 3 with Python 2 to know how Python comes with the new features. Try it to make your Python development easy.

1. Python 2 VS Python 3:
Essential Features
for Modern
Development

2. Unicode Support
VS
Python 2 Python 3
In Python 2, strings are by
default ASCII-encoded, and
Unicode strings need to be
explicitly declared using
the u"string" syntax.
Python 3 natively supports
Unicode strings, allowing you to
work with text in different
languages and character sets
more easily.

3. Print Function
VS
Python 2 Python 3
In Python 2, print is a
statement and does not require
parentheses (e.g., print
"Hello").
In Python 3, print is a built-in
function, requiring parentheses
around the arguments
(e.g., print("Hello")). This change
aligns the print statement with
other function calls.

4. Division Operator
VS
Python 2 Python 3
In Python 2, dividing two
integers using the division
operator (/) truncates the result
to the nearest floor value,
resulting in an integer. To obtain
a float result, you need to use
the floor division operator (//).
In Python 3, the division operator
(/) always returns a float result,
even when dividing two integers.
This behavior helps avoid
unexpected results and improves
the accuracy of mathematical
operations.

5. Iteration & Looping
VS
Python 2 Python 3
In Python 2, the traditional
syntax for looping over iterable
objects is for x in
xrange(iterable).
Python 3 introduced a simplified
syntax for looping over iterable
objects using the for x in
iterable syntax. This syntax is
more concise and intuitive
compared to the traditional for x
in xrange(iterable) syntax in
Python 2.

6. Exception Handling
VS
Python 2 Python 3
Python 2 has limited exception
handling capabilities, lacking the
'as' keyword and the 'finally'
clause.
Python 3 improved the exception
handling syntax, making it more
consistent and intuitive. The 'as'
keyword allows capturing the
exception instance for further
processing, and the 'finally'
keyword ensures the execution of
cleanup code regardless of
whether an exception occurs.

7. VS
Type Hints
Python 2 Python 3
Python 2 does not have built-in
support for type hints, as they
were introduced in Python 3 to
enhance code readability and
maintainability.
Python 3 introduced type hints,
allowing developers to annotate
variables, function parameters,
and return types with type
information. These hints are
optional and can be used by static
type checkers and IDEs for
improved code analysis.

8. VS
f-strings
Python 2 Python 3
Python 2 lacks support for f-
strings and typically uses the
‘format()’ method or the %
operator for string formatting.
Python 3 introduced f-strings, a
concise and convenient way to
format strings. They allow
embedding expressions inside
string literals, enclosed by curly
braces '{}'.

9. Python 2 and Python 3
Navigating the Development Landscape
In today's rapidly evolving technological landscape,
understanding the differences between Python 2
and Python 3 is crucial for successful development
of applications. And this is why Python
Development Services have to always be prepared
for the latest and trending changes to the language
for better development.
