Python for loop only writes one json file

April 19, 2022

I am trying to write a Python script that writes x amount of files in a for loop, but at the moment it only writes a single file, item-{x}.json, instead of 110. How can I fix it?

import json
  
for x in range(110):
    dictionary = {
        "name":"Item #{x}",
        "properties":{
            "creators":[
                {
                    "address":"H5ZQGeTv23nJRcFmEprRLuM9cTeJMajYvf2k1JhuLhE2",
                    "share":100
                }
            ]
        },
    }
  
    json_object = json.dumps(dictionary, indent = 2)
    with open("item-{x}.json", "w") as outfile:
        outfile.write(json_object)

>Solution :

use f-strings like this:

import json
  
for x in range(110):
    dictionary = {
        "name":f"Item #{x}",
        "properties":{
            "creators":[
                {
                    "address":"H5ZQGeTv23nJRcFmEprRLuM9cTeJMajYvf2k1JhuLhE2",
                    "share":100
                }
            ]
        },
    }
  
    json_object = json.dumps(dictionary, indent = 2)
    with open(f"item-{x}.json", "w") as outfile:
        outfile.write(json_

object)
