Sometimes I want to show all of the rows in a pandas DataFrame, but only for a single command or code-block.
Of course I can set the "max_rows" display option to a large number, but then I have to repeat the command afterwards in order to revert to my preferred setting. (I like 12 rows max, personally).
pd.options.display.max_rows=1000
myDF
pd.options.display.max_rows=12
That's annoying.
I read in the documentation that I can use the pd.option_context() function to accomplish this if I combine my command with a "with" statement:
with pd.option_context("display.max_rows", 1000): myDF
I couldn't get that to work, (no output is returned). But I think such a solution would still be too much typing for routine incidental usage!
I wish there was some quick pythonic way to override the display options!
Does one exist? Have I overlooked something?
I like how one can alter the # of rows that the .head() function outputs by passing it an argument for the # of rows, but it still must be lower than the "display.max_rows" setting...
I know I could keep the "display.max_rows" setting really high all the time, and then tack a .head(12) function on most of the time, but I think most people would agree on how annoying that would be.
I am indeed aware that one can view all (or most of?) the values in a pandas Series by passing it to a core function such as list(). But that is tricky to do with a DF. Furthermore, it's hard to read when it's not in a tabular format.
Similar to the solution for my first question, I imagine there's probably a way to write my own function (to be placed in a startup script), but I'm not sure the best way to write it.
You could write a function that explicitly calls display
E.g., consider this function:
from IPython.display import display
def show_more(df, lines):
foo = 1
display(df)
foo = 2
When I call the function (just tried it):
>> show_more(df, 1000)
... # <- Shows here the DF
then it displays the dataframe, even though the line foo = 2 is executed after. It follows that you can set the options instead of the line foo = 1 and unset it in the line foo = 2. In fact, you can just use the context manager from your question, probably.
