Hi! My code is > db = {} > > def display(): > keyList = db.keys() > sortedList = keyList.sort() > for name in sortedList: > line = 'Name: %s, Number: %s' % (name, db[name]) > print line.replace('\r', '')
And it gives following error: > for name in sortedList: > TypeError: 'NoneType' object is not iterable How can sortedList variable turn into NoneType? I just don't get it... -- http://mail.python.org/mailman/listinfo/python-list
