從大量的一維列表中創建一個二維列表python

Question

大家好，我在從許多1D列表中創建2D列表時遇到了麻煩。 我的代碼如下

  lis=[average, average1, average2, average3, average4, average5, average6, average7, average8, average9]
  totalaverage= 3


  print
  print "Station 1 = Station 0 from menu. Please read all other stations accordingly"
  print
  for i,x in enumerate(lis):
  if x < totalaverage:
    aboveaverage = " {} average is less than {}".format(i+1,totalaverage )


    option = 0
    comicdb = []

    record = {}
    record = aboveaverage
    comicdb.append(record)
    print comicdb


    elif x > totalaverage:
     belowaverage = "{} average is greater than {}".format(i+1,totalaverage)
     print belowaverage

當我打印comicdb時，我得到以下結果。

[' 1 average is less than 3']
[' 2 average is less than 3']
[' 3 average is less than 3']
[' 4 average is less than 3']
[' 5 average is less than 3']
[' 6 average is less than 3']
[' 7 average is less than 3']
[' 8 average is less than 3']
[' 9 average is less than 3']
[' 10 average is less than 3']

我想知道的是。 有沒有可以添加的代碼，因此我可以將所有這些單個列表合並為一個雙重列表，以便我的代碼在打印時看起來像這樣。

[[' 1 average is less than 3'],
[' 2 average is less than 3'],
[' 3 average is less than 3'],
[' 4 average is less than 3'],
[' 5 average is less than 3'],
[' 6 average is less than 3'],
[' 7 average is less than 3'],
[' 8 average is less than 3'],
[' 9 average is less than 3'],
[' 10 average is less than 3']]

本質上，我希望將所有這些單獨的列表合並為一個雙重列表，以便可以使用雙重列表單獨訪問每個列表。 我想稍后在代碼中分別打印每個列表。

在python中，您可以將列表追加到列表中。

new_list = []
for i,x in enumerate(lis):
if x < totalaverage:
    aboveaverage = " {} average is less than {}".format(i+1,totalaverage )
    option = 0
    comicdb = []
    record = {}
    record = aboveaverage
    comicdb.append(record)
    new_list.append(comicdb)
    print comicdb

    elif x > totalaverage:
        belowaverage = "{} average is greater than {}".format(i+1,totalaverage)
        print belowaverage
print new_list
