检查数组中是否存在elementhash并更新它，否则插入i

Question

我有一个哈希列表：

[
  {'key1': 'value1', 'key2': some_object},
  {'key1': 'value21', 'key2': some_object2},
  {'key1': 'value133', 'key2': some_object3}
]

检查带有'key1': 'value133'的元素是否存在（如果我的情况是存在的）并更新它（比如说'key1': 'value133', 'key2': some_object333}或者插入它（{'key1': 'value133', 'key2': some_object3}）最简单的方法是什么？你知道吗

Answer 1

l = [
  {'key1': 'value1', 'key2': 'some_object'},
  {'key1': 'value21', 'key2': 'some_object2'},
  {'key1': 'value133', 'key2': 'some_object3'}
]

d = any(d for d in l if d['key1'] == 'value133')
if  d:
    d['key2'] = 'some_object333'
else :
    l.append({'key1': 'value133', 'key2': 'some_object3'})

print(d)

像这样做使用any()
