To replace values in a NumPy array by index in Python, use simple indexing for single values (e.g., array[0] = new_value), slicing for multiple values (array[start:end] = new_values_array), boolean indexing for condition-based replacement (array[array > threshold] = new_value), and...

This means that you can access the values stored in a dictionary using the associated key rather than an integer index.The keys in a dictionary are much like a set, which is a collection of hashable and unique objects. Because the keys need to be hashable, you can’t use mutable objects...
