使用 Python 在将 object 复制到新文件的数组中之前尝试增加数组中的 JSON object 值

Question

I have the following JSON which i am importing in python

[{
"title": "Reference Addition",
"ref_date": 20200110,
"country": "ASIA",
"ref_internal": "1",
"ref_external": "1"
}]

after import i have saved the data in a variable and changing the values of the JSON Objects to whats needed

# open the file and load the data
with open(myfile, 'r') as f:
data = json.load(f)

changing the values of the objects with following

# edit the elements of the JSON Object array
for obj in data:
    obj['title'] = ['title'] + 1
    obj['ref_internal'] = ['ref_internal'] + 1
    obj['ref_external'] = ['ref_external'] + 1

After changing i am copying the original data with changed values to a new file

# create n copies of the array
copied_data = [copy.deepcopy(data) for _ in range(n)]

and saving into a new file using this

with open('JSON\NEW_DATA.json', 'w') as f:
json.dump(copied_data, f, indent =4)

but each time i want save the array i would like the above values to be incremented but i am struggling to get that done

I keep getting this error for all the fields

obj['title'] = ['title'] + 1
TypeError: can only concatenate list (not "int") to list

It might be a silly mistake but I am new to Python and JSON any help of guidance on how i can do that will really help me learn.

Answer 1

I got it to work by using the copy and copy_num variable copied_obj["ref_internal"] = f"{obj['ref_internal']} - {copy_num}"
