如何将多个列表从一个变量变成一个列表(odoov11)?

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

我有一个字段:

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

我列出了这个字段,我得到了很多列表:

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

控制台打印:

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

我需要这样的东西:

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

我尝试了很多方法,但我只得到这样的结果:

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

控制台打印:

['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']

我做错了什么?

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