win10怎么安装python

安装步骤:

先到python的官方网站下载软件,打开官网后,选择downlad项目,然后选择需要下载的大版本,2.7还是3.4,一直在用2.7,比较好用:

选择完版本后,进入后一个页面,在这个页面可以选择操作系统及对应的版本,win下注意分64位和32位版本,不要下错了;

32位的程序大约为17.5M,建议非官网下载的还是要比对下MD5以防万一,在上一个页面就有MD5值。核对完成后双击安装,首先是询问是为所有用户还是为当前用户安装,用缺省的就行;

下一步后是选择安装目录,这个看个人喜好了,不过还是要记一下目录,因为缺省的代码也会放在这个目录下;

下面继续缺省配置选择就开始安装了,python在安装过程中要执行一些角本,因些需要至少有system的权限才可以安装:

安装完成,但在win10在任务栏和桌面上都未生成图标,使用起来麻烦些,在开始窗口打开所有应,按字母找到python程序项,右键选择固定在任务栏或屏幕

学习python语言需要用到什么软件,内存多大?

我用的vscode写的,还不错,笔记本的话8G内存的主流笔记本基本都能胜任,它对硬件要求并不高

/usr/bin中的python3.6m 中的m是什么意思?和python3.6有什么区别?

Credit for this goes to chepner for pointing out that I already had the link to the solution.

Python implementations MAY include additional flags in the file name tag as appropriate. For example, on POSIX systems these flags will also contribute to the file name:

--with-pydebug (flag: d)

--with-pymalloc (flag: m)

--with-wide-unicode (flag: u)

via PEP 3149.

Regarding the m flag specifically, this is what Pymalloc is:

Pymalloc, a specialized object allocator written by Vladimir Marangozov, was a feature added to Python 2.1. Pymalloc is intended to be faster than the system malloc() and to have less memory overhead for allocation patterns typical of Python programs. The allocator uses C's malloc() function to get large pools of memory and then fulfills smaller memory requests from these pools.

via What's New in Python 2.3

Finally, the two files may be hardlinked on some systems. While the two files have different inode numbers on my Ubuntu 13.04 system (thus are different files), a comp.lang.python post from two years ago shows that they once were hardlinked.
