load() missing 1 required positional argument: 'Loader'

This error message is raised when the `load()` function is called without providing an argument for the `Loader` parameter.

The `load()` function is used to deserialize a JSON object or string into a Python object. It takes two optional parameters: `object_hook` and `parse_float`, and one required parameter: `Loader`.

The `Loader` parameter specifies the JSON parser to use when deserializing the JSON object. It can be one of the following values: `json.JSONDecoder`, `json.JSONDecoder` with `object_pairs_hook`, or `simplejson.JSONDecoder`.

To fix the error, provide a valid value for the `Loader` parameter when calling the `load()` function. For example, if you want to use the default JSON decoder, you can pass `json.JSONDecoder` as the value for `Loader`.

Example:

import json

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

# Using the default JSONDecoder
data = json.load(json_str, Loader=json.JSONDecoder)

print(data)

Output:

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