上面的都是windows系統平臺的安裝包，哇，有沒有後宮三千，不知道“臨幸”哪一個的感覺~.~

看了下面的你就明白啦。

毫無疑問，x86適合32位操作系統；x86-64適合64位操作系統。然後呢，下面是官網的一些解釋：

https://www.python.org/downloads/release/python-350/

• The binaries for AMD64 will also work on processors that implement

the Intel 64 architecture. (Also known as the "x64" architecture, and
formerly known as both "EM64T" and "x86-64".) They will not work on
Intel Itanium Processors (formerly "IA-64").

• Windows users: If installing Python 3.5 as a non-privileged user,

you may need to escalate to administrator privileges to install an
update to your C runtime libraries.

• Windows users: There are now "web-based" installers for Windows

platforms; the installer will download the needed software components at
installation time.

• Windows Users: There are redistributable zip files containing the

Windows builds, making it easy to redistribute Python as part of another
software package. Please see the documentation regarding Embedded Distribution for more information.It is intended for acting as part of another application, rather than being directly accessed by end-users.

簡單的說就是有下面3種途徑獲取python：

1. web-based installer 是需要通過聯網完成安裝的

2. executable installer 是可執行文件(*.exe)方式安裝

3. embeddable zip file 嵌入式版本，可以集成到其它應用中。

上面3種途徑，如果有網絡，可以選擇web-based；
