Given a date I need to separate data into weeks

[metulburr]

your not saving values.strip()
you need to do this if your doing it that way...

values = values.strip()

>>> s = 'test\n'
>>> s
'test\n'
>>> s.strip()
'test'
>>> s
'test\n'
>>> s = s.strip()
>>> s
'test'

But i meant to do

cleanedData.append(datetime.strptime(values.strip(), '%d/%m/%Y %H:%M'))
