我正在将文本文件列表加载到dask数据框中。每个文本文件都有多行字典（用换行符分隔）。对于文本文件的每一行，我都会进行“ remove_escapes”中定义的一些小处理并返回一个列表。我打电话给flatten以确保我有一个列表（而不是列表列表）。
input_file_list = self.get_file_list()
posts_db = db.from_sequence(input_file_list)
posts_db = posts_db.map(self.remove_escapes).flatten()
posts_df = posts_db.to_dataframe()
posts_df = posts_df.compute()
def remove_escapes(self,chunk_file):
json_list = []
with open(chunk_file,'r') as fp:
for line in fp:
line = line.strip()
if line:
line = line.replace("\\\\","\\")
json_data = json.loads(line)
json_list.append(json_data)
return json_list
我明白了：

如上所示，索引被重复。有没有办法确保索引排序正确并不断增加？
