- Dictionary keys are case sensitive, the same name but different cases of Key will be treated distinctly.
- If there are duplicate keys in a dictionary, the last key-value pair will override the previous ones.
Characteristics of Dictionary Values
- Values in a dictionary can be of any data type and can be duplicated.
- Key-Value is provided in the dictionary to make it more readable.
