ipython-notebook

问题 I have a notebook that is going to print off hundreds of lines. Is there anyway to have the next line print above the last one? As in: Output_n ... Output 2 Output 1 Instead of: Output1 Output2 ... Output_n 回答1: Kind of! from IPython.display import clear_output , then calling clear_output() will clear everything. Then you reprint everything starting from Output_n. It's... not ideal. Here's a link. 来源： https://stackoverflow.com/questions/24439629/ipython-notebook-print-above-last-line

问题 I loved the R magic in ipython notebook. I had to switch to a new server and heard that a huge headache can be taken out by installing everything through anaconda. However, R magic doesn't seem to work, which is half the reason I use ipython notebook. After installing anaconda, I open a notebook and simply type the following. %load_ext rmagic %%R print("hi") This produces a Runtime error I can't get to the bottom of: --------------------------------------------------------------------------

问题 I want to change the font type in Markdown cells when I am editing them. How Can I do that?

问题 Using ipython notebook, a pandas dataframe has 4 columns: numerator1 , numerator2 , denominator1 and denominator2 . Without iterating through each record, I am trying to create a fifth column titled FishersExact. I would like the value of the column to store the tuple returned by scipy.stats.fisher_exact using values (or some derivation of the values) from each of the four columns as my inputs. df['FishersExact'] = scipy.stats.fisher_exact( [[df.numerator1, df.numerator2], [df.denominator1 -

问题 Is it possible in an IPython-Notebook cell to get the previous (above) cell content ? I can see previous output with %capture magic function but I don't find how to get the previous cell content. 回答1: I didn't find how to get the previous content cell in a cell. But I found another solution, creating a custom magic notebook function to capture the cell content and work with that. 回答2: You can get content of the last executed cell with: In[len(In)-2] 回答3: %recall jupyter_notebook_cell_number

问题 I have an IPython Notebook that is using Pandas to back-test a rule-based trading system. I have a function that accepts various scalars and functions as parameters and outputs a stats pack as some tables and a couple of plots. For automation, I want to be able to format this nicely into a "page" and then call the function in a loop while varying the inputs and have it output a number of pages for comparison, all from a single notebook cell. The approach I am taking is to create IpyTables and

问题 I'm using an IPython notebook ( ipython notebook & ), but when I try to print something to get any output by simply giving the variable name ans pressing Shift + Enter, instead of getting the output in notebook (next to the cell), I get it in the terminal from where I launch the notebook. I want to see the output in the notebook itself, next to the concerned cell. I'm facing this problem lately, previously it was working fine. 回答1: This code produces the same issue on my machine: import sys
