先来点：

#----- 1v1 = [1,2,3,4]v1.append(123)print(v1)  #[1, 2, 3, 4, 123]#-----2v1 = {
    'k1':'v1'}v1['k2'] = 'v2'print(v1) #3{'k1': 'v1', 'k2': 'v2'}#------3data = [    [11,22,33],    [44,55,66]]print('先',data)data[0].append(data[1])print('后',data)# 先 [[11, 22, 33], [44, 55, 66]]# 后 [[11, 22, 33, [44, 55, 66]], [44, 55, 66]]

 

再来点：

data = [    [11,22,33],    [44,55,66]]data[0].append(data[1])   #前data[1].append(77)       #中print('后',data[0][3])      #后# 前 [[11, 22, 33, [44, 55, 66]], [44, 55, 66]]# 中 [[11, 22, 33, [44, 55, 66, 77]], [44, 55, 66, 77]]# 后 [44, 55, 66, 77]

 

不急，再来点：

data = [    {
     'k1':'v1'},    {
     'k2':'v2'}]for item in data:    item['kk'] = 'vv'print(data)#[{'k1': 'v1', 'kk': 'vv'}, {'k2': 'v2', 'kk': 'vv'}]

 

不能再来了，来点爽快的：

msg_list = [    {'id':1,'content':'xxx','parent_id':None},    {'id':2,'content':'xxx','parent_id':None},    {'id':3,'content':'xxx','parent_id':None},    {'id':4,'content':'xxx','parent_id':1},    {'id':5,'content':'xxx','parent_id':4},    {'id':6,'content':'xxx','parent_id':2},    {'id':7,'content':'xxx','parent_id':5},    {'id':8,'content':'xxx','parent_id':3},]"""## ---- 前戏# v = [row.setdefault('child',[]) for row in msg_list]   #这个写法 好像 有点难# print(msg_list)for item in msg_list:   #换个 简单一点点    item['child'] = []print('***',msg_list)"""msg_list_dict = {}for item in msg_list:    item['child'] = []    msg_list_dict[item['id']] = itemresult = []for item in msg_list:    pid = item['parent_id']    if pid:        msg_list_dict[pid]['child'].append(item)    else:        result.append(item)print(result)"""     **********************展示效果**************************[    {'id': 1, 'content': 'xxx', 'parent_id': None, 'child': [        {'id': 4, 'content': 'xxx', 'parent_id': 1, 'child': [            {'id': 5, 'content': 'xxx', 'parent_id': 4, 'child': [                {'id': 7, 'content': 'xxx', 'parent_id': 5, 'child': []}]}]}]},     {'id': 2, 'content': 'xxx', 'parent_id': None, 'child': [        {'id': 6, 'content': 'xxx', 'parent_id': 2, 'child': []}]},     {'id': 3, 'content': 'xxx', 'parent_id': None, 'child': [        {'id': 8, 'content': 'xxx', 'parent_id': 3, 'child': []}]}]"""
