hey. If I want to perform a roll-up function on my dataframe, how should i go about it
Hey, Nice tutorial. Why don;t you use the command : shift+tab, for the documentation by clicking and pressing that command on that specific function?
Good Video
@codebasics, At time 2:49 in some rows it is showing "none" and in some it is "NAN". Kindly explain.

Thanks for your Video ! Can you please let me know if we can put those collapse and expand functionality in actually generated pivot table in excel using python ??

How do I write in to existing csv/excel file by adding new column? i.e., If I have a data in one column (column A) and want to add one column with conditional formula which will show "Yes/No" against all the values of Column A in new Column B, how can we do it? e.g. I have one column A containing the Talk time (in secs) of people. In new column B, I want to put "Yes/No" based on the condition that if Talk time is less than 30 sec its "Yes" else "No". How can I do that?
Can you please tell me how to use the mode function in the aggfunc. I have a categorical data set , i tried this ''''''outlet_size_mode = train.pivot_table(values='Outlet_Size', columns='Outlet_Type',aggfunc=(lambda x:mode(x).mode[0]) )'''''' , below error is coming , error : '

pandas can handle much more larger datasets then excel. Excel has limit on how many rows it can handle whereas pandas can handle millions of rows seamlessly. In terms of visualization also jupyters next gen version jupyter lab has come out which can handle rendering of many many rows very efficiently. I will add a tutorial on that in future.
Hi Sir, im interested to learn python and related modules for data science or data analyst
