How to turn multiple lists from one variable into one list (odoov11)?

Question

I have a field:

 overtime_50 = fields.Char(readonly=True, default='00:00')

I make a list of this field and i get so many lists:

def _compute_sum_50(self):
    for record in self:
    x = [record.overtime_50]
    print(x)

Console print:

['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']
['00:00']

I need to get sometinh like this:

['00:00','00:00','00:00','00:00','00:00','00:00','00:00','00:00','00:00']

I try many ways, but i only get results like this:

def _compute_sum_50(self):
    for record in self:
        x = [record.overtime_50]
        print(list(chain.from_iterable(x)))

Console print:

['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']
['0', '0', ':', '0', '0']

What can i do wrong?

Answer 1

def _compute_sum_50(self):
  x = [record.overtime_50for record in self] # Use List Comprehension
  print(x)
