#💢💢Get a method and its documentation for a particular use case without remembering its name or even the module it belongs to.💢💢 #1.Get a list of all available modules #help('modules') #Example : help("math") #2.Import a module from the list of modules #import #Ex : import time # OR #from import * #Ex : from abc import * #3. Importing entire module #import module1, module2, module3 #Ex: import math,time,array #3.Importing select objects from a module #from import , #i). To import single object from math import pi #ii). To import multiple objects from math import sqrt,pow,ceil #4.Get the available class/functions of the module #dir() print(dir(math)) #5.Get the documentation of the class/method of the module #help(.) #Ex: print(help(math.pi)) #💥Please Note : After importing a module, to access one of the functions , you have to specify the name of the module and the name of the function , separated by a dot (also known as a period) .This format is called dot notation #.() #Ex : math.ceil(-6) #💥Please Note : Avoid using #from import * form of the import statement, it may lead to name clashes if you use plain import , no problems occur #6.Importing a module which is stored inside another module #from import [as ] #Ex. from numpy import array from numpy import array as na #Here, na is the alias name for product.views submodule #Important #The built-in functions of Python are always available ;one needs not import any module for them #7. Importing built-in functions #() #List of some built-in functions #len() , pow() , str() , int() , float(), range() , type() , etc. #Precaution : #Do not use module name with imported object if imported through from import command because now the imported object is part of your program's environment #Ex. from math import pi #Valid command 👇 print(pi) #Invalid command 👇 try: print(math.pi) except NameError: print("Invalid Command") #I hope my small tutorial will help you to understand this concept . #Thanks 🙂
