Error In Xlrd module - xlrd

Question

apologies for my long description. i am not left with any options...
basically, i have written a XML parser in python. which extracts the data from XML tag and writes the data in to Excel sheet using xlsxwriter module. once the excel sheet is created i read the data in excel using xlrd package,process the data and then update my result based on condition in the same excel in result column. now, my problem is, when the Excel is already created and present in the path my program is just working fine but when i delete the Excel and run the program it throws an error as below:
Traceback (most recent call last):
File "AMS_parse.py", line 71, in <module>

#Close the work book after writing
try:
workbook.close()
except:
# Handle your exception here.
print("please close the AMS.xlsx file")
please throw some light on how to correct the error.

Answer 1

You need to close workbook before opening rworkbook.
In fact, you shouldnt use a reader, make your calculations in workbook directly.
