[英]How to replace list of list in python
我有這個清單清單
listoflist = [[['I', 'nvestment activity during the year is summarised as fol', 'l', 'ows:'],
['InterFace-Light', 'InterFace-Light', 'InterFace-Light', 'InterFace-Light'],
[[9.0], [9.0], [9.0], [9.0]]],
[(45.40929412841797, 167.94473266601562, 49.90929412841797, 178.0337371826172),
(47.360496520996094, 167.94473266601562, 241.59832763671875, 178.0337371826172),
(238.8065185546875, 167.94473266601562, 243.3065185546875, 178.0337371826172),

[[['Cost'],
['InterFace-Bold'],
[[9.0]]],
[(526.6923828125, 189.15679931640625, 544.8453979492188, 199.52481079101562)]]
[[['Additions', '£’', '000'], ['InterFace-Bold', 'InterFace-Bold', 'InterFace-Bold'],

[(56.747901916503906, 199.1571044921875, 95.19589233398438, 209.52511596679688),
(523.3358154296875, 199.1571044921875, 532.69580078125, 209.52511596679688),

我想將listoflist[0][0][0]
替換為['Investment activity during the year is summarised as follows:'], ['Cost'], ['Additions', '£'000']
這是我當前的代碼:
new_list = [['Investment activity during the year is summarised as follows:'],
['Cost'],
['Additions', '£’000']]
for i in listoflist:
i[0].pop(0)
for ii in new_list:
i[0].insert(0, ii)
替換列表Python列表中的值無濟於事
根據您要執行的操作(替換或插入),有兩個選項:
要插入:
for ls in listoflist:
ls.insert(0, "Investment activity during the year is summarised as follows:")
取代:
for ls in listoflist:
ls[0] = "Investment activity during the year is summarised as follows:"
編輯:
更換:
listoflist[0][0] = "value1"
listoflist[1][0] = "value2"
listoflist[2][0] = "value3"
插入:
listoflist[0].insert(0, "value1")
edit2:我想我終於明白了你想做什么:
for ls in listoflist:
if ls[0] == ["I", "nvestment activity during the year is summarised as fol", "l", "ows:"]:
ls[0] = new_list[0]
elif ls[0][0] == ["Cost"]:
ls[0] = new_list[1]
elif ls[0][0] == ["Additions", "£’", "000"]:
ls[0] = new_list[2]
