Creating a JSON Array in Python using contents from a file

Question

Well, I have a list of numbers inside of a file called "codes.txt", and I'm trying to sort them into an array like this:

{
  codes: [
    "430490",
    "348327",
    "923489"
  ]
}

Or just simply ["430490", "348327", "923489"]. How would I do this? I'm not trying to output this into a file, but create a variable that contains that JSON array. I have this so far:

codefile = open('codes.txt', 'r')
codelist = logfile.readlines()
codefile.close()
for line in codelist:
  # ?

Answer 1

This should be enough:

with open('codes.txt', 'r') as codefile:
    data = {
        'codes': list(codefile)
    }
