Delete the Python script for the parent account in the voucher table account

Last week, met a pit dad thing, is the manager asked me to Excel format voucher form (a table in a financial account) in addition to the account of the last level of the total deletion, which makes not proficient in office I am very headache, because the voucher is only one year a hundred thousand of records (manual words from the early delete to the end of the night can be deleted). Then I wondered if I could get Excel into MySQL and then use Python to handle it. Because Python is very handy for working with MySQL, I finally wrote a little program to get this done.
