我有一个名为tuples的列表，我想根据给定的日期范围对其进行索引。例如，给定2019-11-10（开始日期）和2019-11-08（结束日期），我想返回一个仅包含该日期范围内信息的namedtuple列表。我该怎么做？多谢各位

未经测试，但类似于：

from datetime import datetime

format = '%Y-%m-%d'
start = datetime.strptime('2019-11-08', format)
end = datetime.strptime('2019-11-10', format)

# concise version
output = filter(lambda tup: start < datetime.strptime(tup['date'], format) < end, your_list_of_tuples)

# verbose version
output = []
for tup in your_list_of_tuples:
  date = datetime.strptime(tup['date'], format)
  if start < date < end:
    output += date

请注意，您从第10个开始，到第8个结束，我假设这是一个输入错误，然后切换。您可能还需要>；=和<；=用于比较
