Python involved in what software, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

In the face of more and more versions of the python environment, do you know anything about the development of the python environment version? Do you know anything about version 3.x?

One of the good things about python in python's study notes is that differences can coexist. Therefore, version 2.6.4 was not deleted, but 2.5.2 was installed directly. If you want to call Python from the Windows command line, you need to set the PATH variable correctly. For Windows 2000, XP, 2003, click Control Panel-> system-> Advanced-> Environment variables. Click on the variable called PATH in the system variables form, then edit the variable and add; C:\ Python25 to the end of it. Of course, it's the correct directory name where Python is located.

The default python shell doesn't work very well, and I installed ipython on the advice of the forerunner. Support syntax highlighting, automatic completion, code debugging and other very good features. I downloaded version 0.10 of *, enter the directory and select.

Ipython-0.10.win32-setup.exe

At the same time, we also need to download a function that can support color display in the shell environment. Go back to the previous page and select

Pyreadline-1.5-win32-setup.exe

After downloading, we first install ipython, because I previously installed two versions of python Learning Notes, so to choose a version during the installation process, I chose version 2.5. Then, install pyreadline, and also select version 2.5 during the installation process. Next, you need to add; c:\ python25\ scripts to the end in the environment variable PATH. Later, type ipython on the command line to enter the ipython interactive environment.

If you find it troublesome, you can choose an one-stop solution Python (x, y). The following part of the introduction comes from search, because it has been reprinted so much that the original text cannot be tested: this is a bit big (close to 400mb), but it comes with many common libraries for scientific computing, as well as the famous PyQt. Some people may think that scientific computing libraries are not very useful.

But dry libraries such as nump,scipy are dependent on many other libraries, and many document-related libraries such as sphinx can be a headache without them. At the same time, PyQt is also notoriously difficult for beginners to configure correctly, and python (x, y) can be used directly after it is installed, which feels great. IDE and some useful tools are also included. This also includes the previously installed ipython.
