Python Error: Cannot access function in class

I've started working with python recently and am totally confused.

I have the following class:

class Vault:

  def __init__(self):

    # used to mock collection (table) of ads
    self._ads = [ {
        'id': '00000000-0000-0000-0000-000000000000',
        'date': str(datetime.now().strftime('%Y%m%d')),
      'time': str(datetime.now().strftime('%H%M%S')),
        'source': 'chron.com',
        'advertiser': 'itunes.apple.com',
        'width': 300,
        'height': 250
    } ]
  def get_ad_by_d(self, d):
    myDate = getTodayDate()
    ads = [ ad for ad in self._ads if ad['date'] == d ]
    if len(ads) == 0:
      return None
    elif len(ads) >= 1:
      return ads[0]
  def getTodayDate():
    return str(datetime.now().strftime('%Y%m%d'))

However when I call it I get the following error:

NameError: global name 'getTodayDate' is not defined

Why can I not access another function in the same class? I wrote this code in textMate, however I've never had issues accessing neighboring functions in the same class when working in Eclipse. Am I missing something?

  def getTodayDate(self):
    return str(datetime.now().strftime('%Y%m%d'))
  def getTodayTime(self):
    return str(datetime.now().strftime('%H%M%S'))

Works to solve the above problem however implementing it in init fails (Found thanks to answers):

  def __init__(self):
    myDate = getTodayDate()
    myTime = getTodayTime()
    # used to mock collection (table) of ads
    self._ads = [ {
        'id': '00000000-0000-0000-0000-000000000000',
        'date': myDate,
      'time': myTime,
        'source': 'chron.com',
        'advertiser': 'itunes.apple.com',
        'width': 300,
        'height': 250
    } ]

I have a similar error that is not solved by adding self:

File "/Users/tai/Desktop/FlashY/flashy/repository/mock.py", line 10, in __init__
    myDate = getTodayDate()
NameError: global name 'getTodayDate' is not defined

solution which was in comments:

  def __init__(self):
    myDate = self.getTodayDate()
    myTime = self.getTodayTime()
    # used to mock collection (table) of ads
    self._ads = [ {
        'id': '00000000-0000-0000-0000-000000000000',
        'date': myDate,
      'time': myTime,
        'source': 'chron.com',
        'advertiser': 'itunes.apple.com',
        'width': 300,
        'height': 250
    } ]

Use self in your method def getTodayDate(self): andmyDate = self.getTodayDate()
