In this learning path you’ll cover a range of core skills that any Python data scientist worth their salt should know. Dictionary is also an unordered collection in Python which has keys and values. objective is to make sure x has a integer value, select all that apply (python 3.xx) Dictionaries are very good at data retrieval you just need to know the key.
