I have a Sample JSON record in a file as below
{ "name":"John", "age":30, "car":"BMW" }
I want to create more JSON records out of it and i want to minimize the i/o by not writing to the file system everytime i create sample record, the code below is to change the age using parameters and hold the JSON records in a list and write to the file system when i am done generating the records.
[{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }]
$$$ the issue i see is, when i write myOutput list it generates 4 records in it but all of them are duplicates, the last json that was produced is written to the whole list. Instead i am looking for something like below
[{ "name":"John", "age":1, "car":"BMW" }
{ "name":"John", "age":2, "car":"BMW" }
{ "name":"John", "age":3, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }]

# Read the sample file with open("C:/myfile.json") as file: originalJSON = json.load(file) # How many sample Records? numberOfRecords = 4 i = 1 myOutput = [] # initializing a dummy list to append my json's while (i <= numberOfRecords): # Change the age originalJSON["age"] = i myOutput.append(originalJSON) i += 1 # After appending all the JSON's to the list i want to write the JSON array to a file with open("C:/multiplerecords.json", 'w') as multipleJsons: json.dump(myOutput, multipleJsons)The output looks like
[{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }
{ "name":"John", "age":4, "car":"BMW" }]
