Writting string to a File - 'str' object is not callable

Question

i am generating a Json-like structure and I need write it to a File, any format of file, but i am getting this error. I have tried written it as Json and string without any luck.

import csv

score = []
test = ''
with open("score_test.txt") as f:
    spam = csv.reader(f, delimiter='|')
    for line in spam:
        score.append(line)

open = """{
    "info": {
        "_postman_id": "",
        "name": "GD-API-Testing-Update",

    },

sample = open + test + close


with open("sample.txt", "a") as f:
    f.write(sample)

This is the error:

Traceback (most recent call last):
  File "/Users/user/Documents/training/TestForPostman/testGenerator.py", line 111, in <module>
    with open("sample.txt", "a") as f:
TypeError: 'str' object is not callable

The for Loop it is appending the generated string I need, and finally closed the structure at the end. I already checked the json structure and it is ok.

You are using open as variable in your code sample = open + test + close which is causing issue. Avoid using any reserved word as a variable. Rename the open variable with something else then it will work.
