我使用的是Windows 8 64位笔记本电脑.我已经在我的电脑上安装了python 2.7.所以我使用easy_install安装了Ipython.我现在可以在C:\ Python27\Scripts中看到一个ipython应用程序文件.当我运行该文件时,它会打开我的cmd,我可以编写代码.但是,当我Ipython notebook在同一文件夹下的cmd中说它没有在浏览器中打开笔记本并给出以下错误 -

C:\Users\UserName>cd C:\Python27\Scripts\

我正在使用Windows机器和2.7版本的python.我已经安装了numpy,现在我正在尝试安装scipy.我尝试使用easy install命令安装它,然后下载zip文件然后运行setup.py文件.

当我尝试通过easy_install安装它时

我是python的新手,我只是尝试了一些列表操作.我有三个清单

A = [10,20,30,40,50,60]
B = [22,44,66,88,12,10]
C = [2,4,6,8,10,20]

我想迭代这三个列表,并且CI的每个值都希望将该值的一半添加到A和B的相应值.例如,对于第一次迭代 - 一半= 2/2 = 1所以A = 10 + 1并且B = 22 + 1所以最终的列表看起来应该是这样的

A = [11,22,33,44,55,70]
B = [23,46,69,92,17,20]
C = [2,4,6,8,10,20]
