Flatten function retrieving the wrong value

I currently have a Python script which uses a flatten function in order to flatten a JSON object, which I will then use json_normalize to turn the flattened JSON into a DataFrame.

Answered 2021-Mar-25 at 12:40

Your flattening function is wrong: with the given jfile it only returns one row, when 5 would be expected.

python 'str' object has no attribute 'items'

Asked 2021-Feb-13 at 06:15

i was trying to loop on txt files which contain dictionary
my code is reading it as string also tried changing those txt file to json but as those words are in single quotes so it say:
Expecting property name enclosed in double quotes
code

ANSWER

Answered 2021-Feb-13 at 06:12

The problem is that read() returns a string, and a string doesn't have any attribute 'items' unlike dictionaries. The other answer which suggested using readlines() is incorrect as well because that would just return a list. (Edit : looks like the answer got deleted, but nevertheless).

Two things:

I assume you copied your text data incorrectly, there was a ] bracket missing at the end.

2) json.load() would have been a great solution to the problem had your data used double quotes instead of single quotes. Turns out even had the data had double quotes, the integer keys and tuples would be a problem like MisterMiyagi pointed out in the comments.

Anyway one work around is to use ast.literal_eval() (which is a bit safer than raw eval)

I keep running into these things, this time with a shared library running a switch statement.

Any ideas on how to read the variables (value1, env) that are set in the library (that echoes the variables just fine) to the Jenkinsfile (that doesn't get the variables)?

Writing postgres bytea to json

Asked 2020-Jun-23 at 06:15

Given:

I have a column in postgres of type bytea. This data was originally a string that was input by a user, and after encryption (the output being bytea) was saved in the db.

Problem:

I want to read the stuff column (bytea) and save it in json form in a file so that I can retrieve it later. I want the stuff data to be saved in bytea format in json as I do not have the decryption key to decrypt the data to a string.

Are there better ways of doing this? Is my approach too naive?
