String	Dictionary
A string is a sequence of characters enclosed in quotes.	A dictionary is a collection of key-value pairs enclosed in curly braces {}.
It is immutable.	It is mutable.
Strings are ordered collection of objects.	Dictionaries are unordered collections of objects.
For example, "hello", '123' etc.	For example, {1: 'a', 2 : 'b'} etc

Assertion (A): Consider the code given below:
d={1: 'Amit', 2: 'Sumit', 5:'Kavita'} d.pop(1) print(d)
The output will be:
Amit #item is returned after deletion {2: 'Sumit', 5: 'Kavita'}
Reasoning (R): pop() method not only deletes the item from the dictionary but also returns the deleted value.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
