由 痴心易碎 提交于 2019-12-09 02:10:28
问题 I want to run a bash script in my ipython Notebook and save the output as a string in a python variable for further manipulation. Basically I want to pipe the output of the bash magic to a variable, For example the output of something like this: %%bash some_command [options] foo bar 回答1: What about using this: myvar = !some_command --option1 --option2 foo bar instead of the %%bash magic? Using the ! symbol runs the following command as a shell command, and the results are all stored in myvar

Getting NameError with Django 1.5 and IPython

由 左心房为你撑大大i 提交于 2019-12-09 00:38:02
问题 I'm running Django 1.5.1, Python 2.7.2, and IPython 0.13.2. If I do "python ./manage.py shell" from within my Django project directory, I get the following error: from django import forms class CommentForm(forms.Form): name = forms.CharField() NameError: name 'forms' is not defined. I know forms is defined as I can see it when it do "dir(forms)". I've noticed that this error only occurs when I'm running iPython within the REPL. If I start the REPL and only use the plain, old Python

问题 The question here is related (but NOT identical) and complementary to Change the "send code to interpreter" (C-c |) command in python-mode . I work on a Mac 10.9.5, Emacs 24.4, Python 2.7.8 and IPython 2.2.0. My idea is to change the C-c C-r emacs command to send a region/line of code in IPython mode to C-RET , as when using R. This is because I usually work with R, but from now on, I am going to be using R and Python (IPython in particular, which I really like), and C-RET --already the send

问题 This question already has an answer here : How do I show the same matplotlib figure several times in a single IPython notebook? (1 answer) Closed 2 years ago .

IPython: quickly dump the output of a cell to file

由 拜拜、爱过 提交于 2019-12-08 17:11:34
问题 It is very easy to save an ipython notebook cell or several cells to a file or to pastebin. But sometimes I want to dump the output of some operation to file. What's the fast way of doing that? %save output Out[56] gives me: Out[56] is neither a string nor a macro. And if I do: %save output str(Out[56]) It works but I lose the pretty-print formatting, and have an automatic .py extension added to the output file name. 回答1: to keep pretty-print formatting try %save output repr(_56) if an object
