In the video, we have explained what is Dictionary in Python.
This is a very useful and informative video for beginners.
A Dictionary is a combination of Keys and Values. These keys or values may be Integers, Floats, Strings.
The Keys and Values are separated by a colon ( : )
A Dictionary is created within { }
Dictionary = { Key1:Value1 , Key2:Value2 , Key3:Value3 }
Properties of a Dictionary :
1. It is a combination of Keys and Values
2. A dictionary doesn't allow duplicate keys in it. (But, we can enter duplicate values)
3. A dictionary is mutable. It means we can add, remove or change the items of a dictionary.
Dictionary functions :
.get('key') - To get the values against a key
.items() - To show all the items of the dictionary
.keys() - To show all the keys of the dictionary
.values() - To show all the values of the dictionary
.pop('key') - It deletes the key alongwith its value
