Python 2 vs. Python 3: Summary. The transition from Python 2 to Python 3 is happening slowly, but it is underway. However, it is a good idea to be aware that there are material differences between Python 2 and Python 3 in case you ever need to deal with code that is written in the version of the language with which you are less familiar. python 2 vs 3 main differences This is basically not a difference between two version, but useful thing to mention here. The idea of future module is to help in migration. We can use Python 3. x If we are planning Python 3. x support in our 2. x code, we can isefuture imports it in our code.
What are the main Python 2 vs 3 2018 differences? There are plenty of differences between these Python programming versions, but here are five of the main ones. 1. Python 2 is legacy, Python 3 is the future. Since Python 2 has been the most popular version for over a decade and a half, it is still entrenched in the software at certain companies. python 2 vs 3 main differences

Note about the speed differences in Python 2 and 3. Jun 08, 2018 Python 3 is the latest generation of the language, many programmers still use Python 2. 7, the final update to Python 2, which was released in 2010. While Python 3 is clearly the future of the language, some programmers choose to remain with Python Main differences. While Python 2 and 3 are quite similar, there are notable differences in code handling and syntax. You should not assume that code written in Python 2 will work smoothly in Python 3 or vice versa. Print. In Python 2, print is a statement not a function. You use it as follows: python 2 vs 3 main differences Python 3 is the version of the language that is currently in development. Overhauled from Version 2, Python 3 was released in late 2008 to address design flaws of previous versions of the language.
