我们可以为每个代码项目都新建一个python environment,这样可以防止不同项目所需的python library版本冲突——具体地,我们可以用Anaconda来管理多个python environment,以便为每种项目创建一个python environment,甚至可以为每个项目都创建一个新的python environment。
For testing, it can also be helpful to call into Excel from a Python prompt (or a Jupyter notebook). This can also be done usingxl_app, and in that case the first open Excel instance found will be returned. You might try this usingwin32comdirectly rather thanxl_app. We do not advi...

multiplesingle-user Jupyter notebook servers(Python/IPython/tornado) Basic principles for operation are: Hub spawns a proxy. Proxy forwards all requests to Hub by default. Hub handles login, and spawns single-user servers on demand. Hub configures proxy to forward url prefixes to the single-user...

matplotlib的教程一般都包含OO或者pyplot两种方法,两种都可以,但是需要注意的是不要混合使用。通常,pyplot用在interactive plotting像jupyter notebook里面,OO-style用在non-interactive像函数或脚本里面能够在大项目里重用的。 在老版本的matplotlib里面还有一个pylab的interface,现在比较少用。
>查看所有的示例 ./bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-3.0.0.jar选择grep例子,将input文件中的所有文件夹作为输入,筛选当中符合正则表达式 dfs[a-z.]+ 的单词并统计出现的次数,最后输出结果到 output 文件夹中。>cd/usr/local/hadoop>mkdir./input>cp./etc/hadoop/*.xml ....
通常,pyplot用在interactive plotting像jupyter notebook里面,OO-style用在non-interactive像函数或脚本里面能够在大项目里重用的。 在老版本的matplotlib里面还有一个pylab的interface,现在比较少用。 有时需要用不同的数据重用一个画图函数,建议采用如下的函数签名 def my_plotter(ax, data1, data2, param_dict): ...
