Solve the following python programming problem given the following code:
@ test.checks ('Str') 
@ test.test_id ('B105') 
def hardcoded_password_string(context) : 
    '**B105: Test for use of hard-coded password strings**

    The use of hard-coded passwords increases the possibility of password
    guessing tremendously. This plugin test looks for all string literals and
    checks the following conditions:

    - assigned to a variable that looks like a password
    - assigned to a dict key that looks like a password
    - used in a comparison with a variable that looks like a password

    Variables are considered to look like a password if they have match any one
    of:

    - "password"
    - "pass"
    - "passwd"
    - "pwd"
    - "secret"
    - "token"
    - "secrete"

    Note: this can be noisy and may generate false positives.

    **Config Options:**

    None

    :Example:

    .. code-block:: none

        >> Issue: Possible hardcoded password \'(root)\'
           Severity: Low   Confidence: Low
           Location: ./examples/hardcoded-passwords.py:5
        4 def someFunction2(password):
        5     if password == "root":
        6         print("OK, logged in")
