CBSE-Class 12-Ch4 -Using Python Libraries - SasikalaJayaprakash
- 1. CBSE CLASS 12 CH-4 USING PYTHON LIBRARIES SasikalaJayaprakash
- 2. Topics to be discussed What is library Importing modules in python program Using python standard library’s functions and modules Creating python library
- 3. What is library • A library refers to a collection of modules that together cater to specific type of needs or applications. • Library have one or more packages and subpackages • Module is independent grouping of code and data(variables , definitions ,statements ,& functions). File extn .py Syntax : help<module name> # to see docstrings , variables , constants , functions
- 4. Importing module Two ways • Entire module import <module name> • To import selected object from a module: from<module name > import <fn name> To import single object To import multiple objects To import all objects from <module name > import *
- 5. library’s functions • Mathematical function len() pow() str() int() float() range() type() abs(x) divmod(a,b) sum(iterable),sum(iterable,args), max(iterable),max(iterable , args), min(iterable),min(iterable,args), Oct (integer) hex(integer) • String functions <str>.join <str>.split <str>.replace
- 6. Using python standard library modules • Random module random() - 0 <=N<1 randint(a , b) a<=N<=b random.uniform(a , b) floating point a<=N<=b random.randrange(stop) random.randrange(start , stop , step) (0,50,10)
- 7. • String module string.ascii_letters string.ascii_lowercase, string.ascii_uppercase, string.digits, string.hexdigits, string.octdigits , string.punctuation , capwords(<str>,[sep=none])
- 8. Creating a python library • Package – collection of modules _init_ .py – special file
- 9. Procedure for creating package
- 10. Creating package • Decide about basic structure of package • Create the directory structure having folders with names of packages • Create a __init__.py file in a package
- 11. Creating package Geometry volume area Rectangle() cube() Square() cubiod() Triangle() Package modules functions
- 14. Importing package geometry , module area
- 15. Area python file coding
- 16. Volume python file coding
Editor's Notes
- #14: Inside geometry folder create python file,init file
