Do I need to uninstall Python 2 before installing Python 3?
You should install python 3 but don’t uninstall python 2. Use virtualenvs so that you can switch between python versions for different projects.
How do I know if Python 3 is compatible?
I think it’s the easiest way you can know if code is compatible at least syntaxically. Have a python3 program load the python modules (without executing them). If the code is compatible, it will load the module, if it isn’t… it will raise a syntax error. Use the ast module.
Why is Python 3 better than 2?
There is better Unicode support in Python 3. In Python 3, text strings are Unicode by default. In Python 2, strings are stored as ASCII by default–you have to add a “u” if you want to store strings as Unicode in Python 2.
Will there be Python 4?
At the current rate of language feature releases (roughly every 18 months), that means we would likely see Python 4.0 some time in 2023, rather than seeing Python 3.10.
Which is better Python 2 or Python 3?
Python 3 is more in-demand and includes a typing system. Python 2 is outdated and uses an older syntax for the print function. While Python 2 is still in use for configuration management in DevOps, Python 3 is the current standard. Python (the code, not the snake) is a popular coding language to learn for beginners.
Why is Python 3 better?
The main advantage of Python 3 is that it is on the cutting edge, so all the new features will be implemented in there rather than being added to Python 2. Python 3 is more consistent language. Python 3 is the present and future of the language.

Python 2.7 is officially dead, but we haven’t seen the last of it quite yet. According to a statement from the Python Software Foundation, the last major version 2.7 will be released in April 2020 (to coincide with PyCon), and then all development will cease for Python 2.
Should I switch Python 3?
Yes, you should, but you have to consider the amount of work which has to go into a port from Python 2.7 to 3. … Python 2.7 does have its advantages because it became the LTS version of Python. Corporate users generally like these long-term support versions, since they reduce porting efforts from one version to the next.
Is Python a dying language?
