Answer 1

As Ekhumoro suggests, sorting of Excel data is easiest done with Pandas. I have tried similar operations with openpyxl, but it's too limited. Pandas can save you many lines of code.

A small example:

from PyQt4 import QtGui , QtCore
import pandas as pd
import numpy as np
import time
import sys

# open excel file
sales = pd.read_excel ("Sales.xlsx" , parse_dates=['Data'] )
# select columns
purchase_patterns = sales [['Total','Date']]
# choose date index
purchase_patterns = purchase_patterns.set_index("Date")
# regroup / resample by week and get subtotals by sum 
resample = purchase_patterns.resample ('W' , how = sum)
