How can I eliminate the white spaces in a JSON file generated by Python?

edit

You can use the json.dumps() function with the separators parameter to eliminate white spaces in a JSON file generated by Python.

The separators parameter is a tuple that specifies the characters used to separate the items in the JSON string. The first character of the tuple represents the separator between items (usually a comma), while the second character represents the separator between keys and values (usually a colon).

Here's an example of how to use json.dumps() with the separators parameter:

import json

data = {"name": "John", "age": 30, "city": "New York"}

# Dump the data to a JSON string without white spaces
json_str = json.dumps(data, separators=(",", ":"))

# Print the JSON string
print(json_str)

Output:

{"name":"John","age":30,"city":"New York"}

As you can see, the resulting JSON string has no white spaces between the items.
