What is the difference between dictionary and list in python?
Moreover, what is a Python dictionary?
Python Dictionary. Dictionary in Python is an unordered collection of data values, used to store data values like a map, which unlike other Data Types that hold only single value as an element, Dictionary holds key:value pair. Note – Keys in a dictionary doesn't allows Polymorphism.
Beside above, can you have a list of dictionaries in Python? Note that the restriction with keys in Python dictionary is only immutable data types can be used as keys, which means we cannot use a dictionary of list as a key . But the same can be done very wisely with values in dictionary. Let's see all the different ways we can create a dictionary of Lists.
Subsequently, one may also ask, what is the difference between list tuples and dictionary in Python?
A tuple or list stores simple elements of whatever data type is required. Tuples are immutable but elements in lists can be modified. As for dictionaries, stated simply a dictionary is a key-value data structure that can be used as an index, i.e. each element has a key and a value.
How does a dictionary work in Python?
Dictionaries work by computing a hash code for each key stored in the dictionary using the hash() built-in function. The hash code varies widely depending on the key; for example, “Python” hashes to -539294296 while “python”, a string that differs by a single bit, hashes to 1142331976.
