How do i find next available column in Xls file and write there using xlrd/xlwt in Python : I am writing a selenium script where I need to store username password information of all the accounts I am creating.
So I am using xlrd and xlwt to write information in an excel file but I am not able to find a way how script automatically detects next available row in the sheet and writes the info there. I am very new to Python.

Thanks in advance.
