NameError: name 'self' is not defined, even though it is?

Question

Can anyone helps me understand why this is this giving me an error? The error being "NameError: name 'self' is not defined". I have a similar class higher up in my code and that works fine?

I'm using 'xlrd' and team is a reference to a workbook.sheet_by_name.

class Rollout:                                  
    def __init__(self, team, name):
        self.team = team
        self.name = name
        self.jobs = {}
        self.start_row = 1
        self.last_row = self.team.nrows

    for i in range(self.start_row,self.last_row):
            try:
                self.jobs[i-1] =   [str(self.team.cell_value(i,0)).upper(), \
                                    str(self.team.cell_value(i,1)).upper(), \
                                    str(self.team.cell_value(i,2)).upper(), \
                                    str(self.team.cell_value(i,3)).upper(), \
                                    str(xlrd.xldate_as_tuple(self.team.cell_value(i,4),0)[3]), \
                                    str(self.team.cell_value(i,5)).upper(), \
                                    str(self.team.cell_value(i,6)).upper()]
            except ValueError:
                print "It look's like one of your 'time' cells is incorrect!"
                self.jobs[i-1] =   [str(self.team.cell_value(i,0)).upper(), \
                                    str(self.team.cell_value(i,1)).upper(), \
                                    str(self.team.cell_value(i,2)).upper(), \
                                    str(self.team.cell_value(i,3)).upper(), \
                                    "missing", \
                                    str(self.team.cell_value(i,5)).upper(), \
                                    str(self.team.cell_value(i,6)).upper()]

The for loop is indented incorrectly resulting in it being outside that method's scope but inside the class' scope. This in turn means that self is not defined.

Python does interpret that loop code in the scope of the class, but without an instance of the object. Sample malformed code:

class Simple(object):
    def __init__(self, a):
        self.a = a

    print("Here we go!")
    for i in xrange(self.a):
        print(i)

Traceback

$ python simple.py
Here we go!
Traceback (most recent call last):
  File "simple.py", line 4, in <module>
    class Simple(object):
  File "simple.py", line 9, in Simple
    for i in xrange(self.a):
