Data handling in python

Data types in python

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 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
