• How do I convert tuple of tuples to list in one line (pythonic)?

  - by ThinkCode

  query = 'select mydata from mytable' cursor.execute(query) myoutput = cursor.fetchall() print myoutput (('aa',), ('bb',), ('cc',)) Why is it (cursor.fetchall) returning a tuple of tuples instead of a tuple since my query is asking for only one column of data? What is the best way of converting it to ['aa', 'bb', 'cc'] ? I can do something like this : mylist = [] myoutput = list(myoutput) for each in myoutput: mylist.append(each[0]) I am sure this isn't the best way of doing it. Please enlighten me!

Also they generate sync SQL scripts when run from command line. What I need is an output as a comprehensive report ( XML , HTML ) suitable for parsing so that I would be able to show similar diff grid in my application ( updated old/new values for each column , added - all values for row , deleted - all values for row and etc... ) .
