在另一个列表中添加一个列表

我在python的另一个列表中添加一个列表。在另一个列表中添加一个列表

a = [ 1, 2, 3, 'a', 'aa'] 
a.insert(3, ['b','a']) 
print a

输出：

[1, 2, 3, ['b', 'a'], 'a', 'aa']

所需的输出：

[1, 2, 3,'b', 'a', 'a', 'aa']

我所要的输出是一个列表，而不是一个列表的层次结构。在这种情况下我应该怎么做？

后续问题

total = [] 
    tname = temp_list[0] 
    if (tname == 'order'): 
     total[0:0] = temp_list 
    else: 
     total[10:10] = temp_list

输入是一个JSON（复制一个子集）：

["order", "7", "39136", "O", "252004.18", "1996-01-10", "2-HIGH", "Clerk#000000470", "0", "ly special requests "] 
["order", "32", "130057", "O", "208660.75", "1995-07-16", "2-HIGH", "Clerk#000000616", "0", "ise blithely bold, regular requests. quickly unusual dep"] 
["line_item", "1", "155190", "7706", "1", "17", "21168.23", "0.04", "0.02", "N", "O", "1996-03-13", "1996-02-12", "1996-03-22", "DELIVER IN PERSON", "TRUCK", "egular courts above the"] 
["line_item", "1", "67310", "7311", "2", "36", "45983.16", "0.09", "0.06", "N", "O", "1996-04-12", "1996-02-28", "1996-04-20", "TAKE BACK RETURN", "MAIL", "ly final dependencies: slyly bold "]

输出（子）：

[["order", "7", "39136", "O", "252004.18", "1996-01-10", "2-HIGH", "Clerk#000000470", "0", "ly special requests "], ["line_item", "7", "182052", "9607", "1", "12", "13608.60", "0.07", "0.03", "N", "O", "1996-05-07", "1996-03-13", "1996-06-03", "TAKE BACK RETURN", "FOB", "ss pinto beans wake against th"], ["line_item", "7", "145243", "7758", "2", "9", "11594.16", "0.08", "0.08", "N", "O", "1996-02-01", "1996-03-02", "1996-02-19", "TAKE BACK RETURN", "SHIP", "es. instructions"], ["line_item", "7", "94780", "9799", "3", "46", "81639.88", "0.10", "0.07", "N", "O", "1996-01-15", "1996-03-27", "1996-02-03", "COLLECT COD", "MAIL", " unusual reques"], ["line_item", "7", "163073", "3074", "4", "28", "31809.96", "0.03", "0.04", "N", "O", "1996-03-21", "1996-04-08", "1996-04-20", "NONE", "FOB", ". slyly special requests haggl"], ["line_item", "7", "151894", "9440", "5", "38", "73943.82", "0.08", "0.01", "N", "O", "1996-02-11", "1996-02-24", "1996-02-18", "DELIVER IN PERSON", "TRUCK", "ns haggle carefully ironic deposits. bl"], ["line_item", "7", "79251", "1759", "6", "35", "43058.75", "0.06", "0.03", "N", "O", "1996-01-16", "1996-02-23", "1996-01-22", "TAKE BACK RETURN", "FOB", "jole. excuses wake carefully alongside of "], ["line_item", "7", "157238", "2269", "7", "5", "6476.15", "0.04", "0.02", "N", "O", "1996-02-10", "1996-03-26", "1996-02-13", "NONE", "FOB", "ithely regula"]]

这给了我父列表中的多个列表，而不是单个列表的预期输出。任何想法是什么原因？

请出示的输入和输出 – jamylak

@jamylak更新 –

这是我的解决方案没有问题，你也没有表明您通过输入迭代如何使目前还不清楚你是如何达到这个问题 – jamylak

>>> a = [ 1, 2, 3, 'a', 'aa'] 
>>> a[3:3] = ['b','a'] 
>>> a 
[1, 2, 3, 'b', 'a', 'a', 'aa']
