Python has several basic data types including numbers (int, float, complex), strings, tuples, lists, and dictionaries. Numbers can be entered using decimal, binary, octal, and hexadecimal notation. Strings can be defined using single or double quotes. Tuples are ordered and unchangeable like lists. Lists are ordered collections that can hold mixed data types. Dictionaries are unordered collections of key-value pairs. Sets are unordered collections with no duplicate elements.

4. String Type
Saravanakumar,AP/CSE 4
• Python string using either single quotes or double quotes. Example : a='Dogs are love‘ or a="Dogs are love"

5. Tuples
Saravanakumar,AP/CSE 5
• Python Tuples are like a list. It can hold a sequence of items. Example : Tuple1 = (1,2,5,6) , Tuple2 = (‘a’, “b”, ‘c’, “d”)

6. Lists
Saravanakumar,AP/CSE 6
• Lists hold different types of data using [] and , . Example : c= ["hey","you",1,2,3,"go"]

8. Dictionary
Saravanakumar,AP/CSE 8
Dictionary is an unordered sequence of data of key-value pair form {key : value} - similar to the hash table type.
a = {1:"first name",2:"last name", "age":33}

Sets
A set is a collection which is unordered and unindexed. In Python sets are written with { }.
thisset = {"apple", "banana", "cherry"}
