dictionary get( ) method vs square bracket notation | Python

Accessing dictionary values using square brackets ([ ]) raises a KeyError if the specified key does not exist, whereas the get( ) method provides a safer alternative by returning None or a default value if the key is missing. With square brackets, there is no way to specify a default value directly, making it less flexible when handling potential missing keys. In contrast, the get( ) method is particularly useful for avoiding errors in cases where the presence of the key is uncertain, as it allows for a default value to be specified, ensuring smoother code execution.
