Line Wrapping in Collaboratory Google results - google-colaboratory

Question

Working on Google Collaboratoy (colab) as Notebook, some cell results a long line text which is bigger than the screen resolution, so it is shown a scrollbar with no wrapping.
Does anyone know how to activate text wrapping to see all text without using scrollbar?
Thanks in advance.
Regards,

Answer 1

Normally on my own machine, I put this the following css snippit in the ~/.jupyter/custom/custom.css file.
pre {
white-space: pre-wrap;
}
But, the above does not work for google colab: I tried creating a file /usr/local/share/jupyter/custom/custom.css, but this didn't work.
Instead, put this in the first cell of your notebook.
from IPython.display import HTML, display
def set_css():
display(HTML('''
<style>
pre {
white-space: pre-wrap;
}
</style>
'''))
get_ipython().events.register('pre_run_cell', set_css)
Explanation: As described in Google Colab advanced output , get_ipython().events.register('pre_run_cell', <function name>)...
defines an execution hook that loads it [our custom set_css() function in our
case] automatically each time you execute a cell
My interpretation is that you need to specify 'pre_run_cell' as the first argument in the events.register, which tells the events.register function that you wish to run your custom set_css() function before the contents of the cell is executed.
This answer was inspired by How to import CSS file into Google Colab notebook (Python3)

from IPython.display import HTML, display
def set_css():
display(HTML('''
<style>
pre {
white-space: pre-wrap;
}
</style>
'''))
get_ipython().events.register('pre_run_cell', set_css)
As Bon Ryu mentioned above, this should solve the issue.
It will wrap your output properly

I use the following snippet:
from IPython.display import HTML, display
def my_css():
display(HTML("""<style>table.dataframe td{white-space: nowrap;}</style>"""))
get_ipython().events.register('pre_run_cell', my_css)

I create a function to help with that. It works with List and String.
def set_wrap(N=100):
''' create a wrap function for list '''
def wrap(obj):
s = str(obj)
out = '<pre>'
while True:
if len(s) < N:
out += s
break
i = s.rfind(' ', 0, N)
if i==-1:
i = N
out += s[:i]+"\n"
s = s[i:]
out += "</pre>"
return out
''' register it '''
Formatter = get_ipython().display_formatter.formatters['text/html']
Formatter.for_type(list, wrap)
Formatter.for_type(str, wrap)
You can use it by just calling set_wrap(80).
