Retrieve the value in the dictionary with the Get () method

Typically, you can specify a key in square brackets to retrieve the value of the key. However, errors can occur when the key is not in the dictionary. Of course, you can also use the try/except exception handling mechanism to solve this problem. However, when the key is not in the dictionary, you can also set the default value through the get () method.
