Let's Learn Python # Day-06 & 07 Deep Dive into Python Lists Python Collections (Arrays) There are four collection data types in the Python programming language: List  is a collection which is ordered and changeable. Allows duplicate members. Tuple  is a collection which is ordered and unchangeable. Allows duplicate members. Set  is a collection which is unordered and unindexed. No duplicate members. Dictionary  is a collection which is unordered, changeable and indexed. No duplicate members. List A list is a collection which is ordered and changeable. In Python lists are written with square brackets. List Methods Python has a set of built-in methods that you can use on lists. Method Description append() Adds an element at the end of the list clear() Removes all the elements from the list copy() Returns a copy of the list count() Returns the number of elements with the specified value extend() Ad...

Let's Learn Python # Day-08 Deep Dive into Dictionaries -01 Dictionary: A dictionary is a collection which is unordered, changeable and indexed. In Python dictionaries are written with curly brackets, and they have keys and values. # Below are some of the Operations @ Dictionaries. student={"name": "abc", "rollnumber":"1234", "branch":"cse"} print(student) print(type(student)) Output:  {'name': 'abc', 'rollnumber': '1234', 'branch': 'cse'} <class 'dict'> # To find the Length of the Dictionary: print(len(student)) Output: 3 #Finding the total items in the Dictionary: student.items() print(student) OUtput: {'name': 'abc', 'rollnumber': '1234', 'branch': 'cse'} #keys d1=student.keys() print(d1) Output: dict_keys(['name', 'rollnumber',...

** Next Hands-on Session will be on 27-June-2020 Stay Tuned.... Let's Learn Python # Day-04 Built-in Data types: python supports dynamic data typing. In Programming, data type is an Important Concept. Variables can Store of different types, and different types can do different things. -> based on assigned values,automatically data type will be constructed to a variable.  a=10 #a is int b=20.45 #b is float c="hello" #c is string two types .  1. simple types.  2. complex types (collection types) 1. simple: ------------------------ int float string --> str boolean -->bool name--> string age --> int income   --> float areYouMarried --> bool ---------------------- name = "Sreeram" or name = 'Sreeram' ------------------------------- name = "xyz" <var> = input(<prompting text>) name = input("Name please ") #string age = int(input("Age ")) income =  float( input("Enter monthly text...
