要检查是否已更改的值是tableau [11:27]，例如“ 46016.0000000”，因此将创建一个新的子列表 感谢您的帮助 我尝试了这段代码，但省略了最后一个值：
new_list = []
if tableau[j][11:27].strip() == tableau[j+1][11:27].strip():
new_list.append(tableau[j])
else:
new_list = []

您可以使用利用捕获组和反向引用的模式来匹配您的值。
(\d+\.\d+)(?: \1)*
然后您可以将匹配项分隔在一个空格上。
import re
regex = r"(\d+\.\d+)(?: \1)*"
test_str = "46016.0000000 46016.0000000 46016.0000000 46016.0000000 46016.0000000 46019.0000000 46019.0000000 46019.0000000 46019.0000000 46019.0000000 46015.0000000 46015.0000000 46015.0000000 46015.0000000 46015.0000000 46016.0000000 46016.0000000 46016.0000000 46016.0000000 46016.0000000 46019.0000000 46019.0000000 46019.0000000 46019.0000000 46019.0000000 46015.0000000 46015.0000000 46015.0000000 46015.0000000 46015.0000000 46016.0000000 46016.0000000 46016.0000000 46016.0000000 46016.0000000"
matches = re.finditer(regex, test_str, re.MULTILINE)
new_list = []
for matchNum, match in enumerate(matches, start=1):
new_list.append(match.group().split(" "))
print(new_list)
输出

您可以循环浏览列表并在出现新值时创建列表
lists = []
lsi = []
for i1,i2 in zip(ls, ls[1:]):
lsi.append(i1)
if i1!=i2:
lists.append(lsi)
lsi = []
print(lists)
答案 2 :(得分：0)
如果您想变得时髦，可以使用列表理解。
from collections import defaultdict
dict_of_lists = defaultdict(list)
[dict_of_lists[i].append(i) for i in big_list]
最后是一个字典，其中的键是唯一值，而该dict的值就是您想要的列表。
