Python to Combine Multiple Excel Worksheets into One Worksheet

>I have one single Excel file with many separate worksheets, and for work I need to combine all these separate worksheets into one single worksheet (I am not worried about formatting, as the format is the same in each sheet, nor am I worried about Excel's row limit).
>Essentially, I am looking for a way to append the data in one sheet to the bottom of the sheet that proceeds it.

>What would be the best way to do this, and how would I go about doing it? Can it be done simply with the xlwt, xlrd, and xutils modules, or (as I was thinking) do I need to convert the sheets to separate csv files, then append the separate csv files, and then write the completed file back into .xls format? >Or perhaps something else?

>As I am really only a Python beginner, any and all help is very much appreciated. Thank you in advance!!

Read the data from the different worksheets using xlrd and then use xlwt to write to a single worksheet in a new excel file. The csv option is probably not useful since it will just add an intermediary step unless you are converting outside of python (i.e. manually).
