I have a file that contains many dictionaries, each line with its own unique dictionary and there are many lines in this file.
{"text": "bla bla", "year": 1933, "price": 43}
{"text": "bla blu", "year": 1934, "price": 41}
{"text": "blu bla", "year": 1935, "price": 43}
{"text": "blu blu", "year": 1936, "price": 44}
Just wanted to emphesize that the dictionaries are not inserted into a list, this is just the way it is, each new row in the file contains a dictionary.
It's a JSON Lines text file format : http://jsonlines.org/
JSON Lines text format, also called newline-delimited JSON. JSON Lines is a convenient format for storing structured data that may be processed one record at a time. It works well with unix-style text processing tools and shell pipelines. It's a great format for log files. It's also a flexible format for passing messages between cooperating processes.
