credentials_searches

Instructions

Create a file credentials_searches.py that contains a function credentials_search which takes no parameters and searches for the keys password and secret in a file called logs.json.

• If both keys are found, the function should create a new json file named 'credentials.json' and save the values of those keys in it.

• If only one of the keys is found, the function should create a new json file named 'credentials.json' and save the value of that key in it.

• If neither key is found, the function should not create the 'credentials.json' file.

• If the 'logs.json' file is empty or is not a json file, the function should not create the 'credentials.json' file.

• If the 'logs.json' file does not exist, the function should not create the 'credentials.json' file.

• If the keys are found in a nested object, the function should create the 'credentials.json' file and save the values of the keys in it.

Usage

Here is an example of how to use the credentials_search function:

With this file logs.json:

{
  "password": "test_password",
  "other": "value",
  "secret": "test_secret"
}

If you run your function:

credentials_search()

Your function should generate this file credentials.json:

{
  "password": "test_password",
  "secret": "test_secret"
}

Hints

• The json module can be used to read and write JSON files.

• The os module can be used to check if a file exists and remove a file.

• Remember that the function should be able to search for the keys password and secret in nested json objects.

• Using the isinstance function could be useful to check if a value is for example a dict.
