Nested Json to csv in python 3

[ravikuc]

I am trying to convert JSON data into a CSV in Python3, but it no longer works with this script, giving me different errors. Anyone know how to fix for Python 3? Thanks.

Below is my JSON data:

{
"fruit": [
{
"name": "Apple",
"binomial name": "Malus domestica",
"major_producers": [
"China",
"United States",
"Turkey"
],
"nutrition": {
"carbohydrates": "13.81g",
"fat": "0.17g",
"protein": "0.26g"
}
},
{
"name": "Orange",
"binomial name": "Citrus x sinensis",
"major_producers": [
"Brazil",
"United States",
"India"
],
"nutrition": {
"carbohydrates": "11.75g",

}
},
{

}
