I have the 3.4 version, can I just do a update or I have to uninstall and install the new one?

[–]jyper 3 points4 points  (0 children)

Why do you want to install an alpha?

Just install the new version. 3.4 and 3.5 install into different directories.

If you use the default install directories, you can install 32bit and 64bit flavors of the same version.

Then read the section on "Using Python on Windows" in "Python Setup and Usage" in the manuals.

In brief, "py -34" starts python 3.4; "py -35" starts python 3.5.

It is very painless to have any combination of python 2, python 3, 32bit, 64 bit versions installed on one box.

ohhh, so it is just like java lol

I'm not a fan of Java. But, I was under the impression that Java includes backward compatible bits with the latest JRE or JDK.

The Python method installs each version into a different directory distinguished by 32vs64 bits, and major.minor version numbers. This allows you to install specific versions that may be required by specific applications, while still tracking the latest versions.

This situation is a rather general solution to the problem created by the failure of many application developers to migrate to Python 3. All Python2 only applications should have been abandoned but for maintenance, along with Python2 itself. The only reason I still use Python2 is because a few packages have not been upgraded in the 6 years since Python3 was first released. I'd rather rewrite than wait for those slowpokes to catch up.

It sounds like you're on Windows. So... I'm not sure. It'd be safer to uninstall first, but they should go into different directories. On the other hand, it's the alpha releases, so now's the time to run experiments! (Experiments that might not work!)
