The document provides an overview of Python sequences, detailing types such as lists, tuples, strings, sets, and dictionaries. It explains sequence operations including concatenation, repetition, membership testing, indexing, and slicing. Additionally, it highlights the unique characteristics of each sequence type and their usage in Python.

The list is a most versatile datatype available in Python which can be written as a list of comma-separated
values (items) between square brackets. Important thing about a list is that items in a list need not be of
the same type.](https://image.slidesharecdn.com/pythonsequence-edureka-170719053022/85/Python-Sequence-Python-Lists-Python-Sets-Dictionary-Python-Strings-Python-Training-Edureka-14-320.jpg)

Tuples
➢ A tuple is a sequence of immutable Python objects.
➢ Tuples are sequences, just like lists. The differences between tuples and lists are, the
tuples cannot be changed unlike lists and tuples use parentheses.
Fruits = ('Mango', 'Apple', 'Grapes‘)
Tuple.index(elem)Index
Tuple.count(elem)Count

Strings
➢ We can create them simply by enclosing characters in quotes.
➢ Python treats single quotes the same as double quotes.
Fruits = 'Mango Apple Grapes'

Dictionaries
➢ Dictionary is an unordered collection of key-value pairs.
➢ It is generally used when we have a huge amount of data.
Example:
Length
