I found this answer helpful in creating my own: import numpy as np np.set_printoptions(edgeitems=30, linewidth=100000, formatter=dict(float=lambda x: “%.3g” % x)) The absurd linewidth means only edgeitems and the window’s width will determine when newlines/wrapping occurs. If I shrink the window a bit, it looks like this, so you may still need to play with the … Read more

Add and execute a regular Python code cell with the following content: from IPython.core.display import HTML HTML(“”” <style> // add your CSS styling here </style> “””) Alternatively (thanks @abalter) use the %%html cell magic: %%html <style> // add your CSS styling here </style>
Update for IPython v0.13: import sys from IPython.core import ultratb sys.excepthook = ultratb.FormattedTB(mode=”Verbose”, color_scheme=”Linux”, call_pdb=1)
I had a similar printing problem when my first code cell was: import sys reload(sys) sys.setdefaultencoding(“utf-8”) Then I’ve commented the second and third lines like this: import sys #reload(sys) #sys.setdefaultencoding(“utf-8”) Reset the kernel and re-ran the program and now my print statements are working properly. Later on, I’ve found that when I was first having … Read more

An alternative to use argparse in Ipython notebooks is passing a string to: args = parser.parse_args() (line 303 from the git repo you referenced.) Would be something like: parser = argparse.ArgumentParser( description=’Searching longest common substring. ‘ ‘Uses Ukkonen\’s suffix tree algorithm and generalized suffix tree. ‘ ‘Written by Ilya Stepanov (c) 2013’) parser.add_argument( ‘strings’, metavar=”STRING”, … Read more
