Answer:
Dictionary
Explanation:
Most Data types do hold only one value as an element, python's Dictionary holds key/value pair. In Python, DICTIONARIES are unordered collection of data. These data are used to store values, for instance in the question given, writing the script that will make use of user input contact names and their associated phone numbers; DICTIONARY is ideal for storing and accessing these associated values.
When creating a python's Dictionary it is worthy of note that dictionary keys are case sensitive. Dictionary, in Python can be created by imputing sequence of elements within - {}, and then you separate {} by ‘comma’. For example;
# Creating contact names
Dict = {}
print("contact name: ")
print(Dict)
