This document discusses Python data types. It explains that variables in Python have a specific data type determined by the interpreter based on the value. The main data types covered are numbers, strings, lists, tuples, dictionaries, sets, and Boolean. Numbers can be integers, floats, or complex. Strings are sequences of characters that can be in single, double, or triple quotes. Lists are ordered and allow duplicate/mixed types while tuples are ordered but unchangeable. Dictionaries contain key-value pairs. Sets hold unique elements without order. Boolean can only be True or False.

1. Data Handling

2. Data Types
• Each and every value we enter in a variable have a data type
• Which is provided by python interpreter as according to data
• A=12
variable
Each value have a data type
which is stetted by python
interpreter

3. Data Types
• Numbers
• String
• List
• Tuples
• Dictionaries
• SET
• Boolean

4. Data Types:Numbers
Integer • 12,56
Float • 12.78
Complex • 12+4i

5. String
• Collection of characters and sequence of characters
• A=“Deepali”
• Variable should be in
• Single quotes(‘Deepali’)
• Double quotes(“Deepali”)
• Multiline values should be in
• Triple double quotes(“ “ “)

6. LIST
• Ordered Sequence
• Contain items
• Homogeneous (same)
• Hetrogeneous(different)
• Flexible data type
• Widely used
• Changeable(Item can be alter)

7. LIST declaration
• F=[1,2.0,”Deepali”]
• Items enclosed within Square brackets
• Comma (Separator)

8. Tuples
• Ordered Sequence
• Unchangable(Tuples can not be altered)
• Tuples uses to protect the data
• Contain items
• Homogeneous (same)
• Hetrogeneous(different)

9. Tuples declaration
• f=(1,2.0,”Deepali”)
• Comma(Seperator)
• Items enclosed within in parenthesis

10. Dictionary declaration
Contains a key : value pair
F={“Rohan”: “Cycle”,”Satyam”: “Car”}
Items enclosed with curly brackets
Comma(Seperator for key:value pair)

11. Dictionary
• Unordered sequence
• Contain key values pair
• Huge amount of data
• Code optimization
• Retrieve values from key

12. SET
• Well defined collection of item
• f={1,2.0,”Deepali”}
• Items enclosed within curly brackets
• Comma (separator)

13. Boolean
• True or False
• Declaration:
Bool1=True
Bool2=False
