In this lecture we will learn:
- Different types of operators in Python
- Use of different operators
- Operation performed between different operators
- Logical operators and their uses
#1
- Types of operators in Python:
1. Arithmetic operators
2. Assignment operators
3. Relational operators
4. Logical operators
5. Unary operators
- Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, division, etc.
- Assignment operation is performed with the help of equal to(=), in which we can assign a value to the variable.
- We can also do the assignment by short-hand which means performing an arithmetic operation and then assigning the value both at the same time.
- We can also assign the values in one line for two variables.
a,b = 5,6
- Unary operator takes a single operand in an expression or a statement.
- Comparison can be performed with the help of relational operators.
- Comparison operators return a boolean value or True or False.
#2
- If you want to combine two or more conditions and then check the relation between them, then logical operators are used.
- Logical operators include And, Or and Not.
- Logical operators follow the truth table for And, Or, and Not operators.
- And the operator returns True when both conditions are true otherwise returns False.
Or the operator returns True when any of the conditions or both the conditions are True otherwise it returns False.
Not the operator reverses the value of the output.

Excellent, have got clear understanding of what operators are, their divisions based on operations, operational utility👌. Thanks a lot for the tutorial series, its helping a lot getting a hold of Python foundations step by step👍 Name of four datatypes with definition --> 1. None = variable with no assigned value 2. Numeric = int, float, complex, bool 3. Sequence = list, tuple, set, string, range 4. Dictionary = a collection of key and value pairs, where keys are unique and immutable like string or numbers

DATA TYPES 1) None :It is simply null vale 2) List : collection of elements.We use [] braces in list.it is mutable type 3) Tuple : collection of elements.we use () braces in tuple. It is immutable type. 4) int : It is interger type datatype that gives only interger value.E.g. 6,8,9 5) float : It is decimal or floating point type data type that gives only floating type values.e.g.5.7 6) complex : It is a datatype which contains complex digits such 6+8j

Four Data Types: 1.None- Variable assigned with no value 2.Numeric: int,float,complex,bool are type of numeric data. In int we have integers, in float we have decimal nos.,in complex we have imaginary nos(generally imaginary nos have "i" but in python we use "j") and in bool we use boolean expression i.e. true or false 3. Range: When we etrayed b/w the values we use range Example- 1 to 10 4.Dictionary: It is used when we have huge data In dictionary for every value we assign different key for each value but in list we have different index for each value.

#quiz 1. None-> When a variable is not assigned any value (in other languages we use null) 2. Numeric-> A variable is numeric when it has a numerical value. It is of four types : a) int->variable has integral value. e.g. a=10 b) float -> variable have floating-point value. e.g. b=10.5 c)complex-> variable having complex value including both real as well as imaginary part. e.g. 2+4j (where j= (-1)^1/2) d) Bool-> For boolean (simply means true or false)

None (When we do not assign any value to the variable) List (It is a group of those values which we can change at any time look like mutable and List also support indexing) Tuple (It is a group of those values which we cannot change look like Immutable and in tuple, we have only two method index, count) set (It is a group of those values which is not repeatable and set is not support indexing because set use the concept of hash) dictionary (It is also a Datatype in python it use the concept of key and value, we use this datatype when we work with huge amount of data)

None: when we assign null value to number list= [a group of mutable values and can contains different element types] tuple=(a group of immutable types and similar to list) set={a group of elements containing unique values} range={series of values that can be expressed using end values} dictionary or mapping={storing values uses keys instead of indexing}

1, None - nothing, none means in other programming language null. 2, numeric - numbers value like 123, -2, 3.4 3. Lists []- list values we can append, remove, push, pop, extend the list. We can join two different list in a single variable. 4. Tuple()- is same as list but it's immutable. We can use count, and index methods here. 5. Set{}- is same like tuple, we can't use index here, because this values are unsequence. 6. String is a collection of characters like 'vinoth', 'manish' 7. Range - we can get the ranges between the two values here range(5) - range(0,5) -> list(0,5,1) -> we can get even numbers between 0 and 5. 8, dictionary or mapping-> its keys and value , keys are unique, ex: ['name':'vinoth', 'department':'cse', 'place':'chennai']

Int(have 4 types that are: decimalform,binaryform,octalform,hexadecimalform)..... Float(if any number have decimal point it is float datatype)..... Complex(in complex suppose 10+20j is 10 is real number, 20 is imaginary number) List is [ ], tuple is ( ), set is { }, int is any, float is any There are totally 14 datatypes

None = variable with not any value assigned Numeric = consists of numbers and is divided into four types: int() complex() float() bool() 3. List[] :- orderded format of strings. 4. Tuple(): - orderded format of strings but value not changeable.more than one string is a tuple else if one it is a string. 5. Set{} : - unordered format of strings.values doesnt repeat 6. Range() :- series of values that follows a certain writting format. 7. Dictionary{} :- usefull for assigning keys to a value eg :- {'Python_Video':11'}. Keys should be unique. Edit:- str() :- a single word/letter/character written in either single or double quotes.

None = Which is used to assign None to a variable means no value in other language we use Null!! Numeric= It includes int float bool complex, Basically it has all inbuilt data types List = This is my favourite datatype which is similar to array but the difference is that you can store different type of value in List and it is created by following syntax: lisy = ['Hey','Telusko'] or you can make anyother sequence like string , tupple in list using list() inbuilt funciton. Tupple = It is similar to list but here we cant change the value after assignment because it is immutable so if you want to change a tupple first convert it into a list and then change your requirements and then again change that list to tupple. For example: tup = (1,2,3,4,5) list = list(tup) list.append(6) list.insert(3,8) tup = tupple(list) Thanks telusko for helping us love from india!!!!

numeric = int,float,complex,boolean int is round number float is used to refer decimal number complex is used to refer (a+bj) boolean is used to check True or False List [is a set of number or strings in a square bracket which is mutable] tuple is ( is a set of number and strings which is immutable)

None= a varible with no assingment value. List are used to store multiple items in a single variable. Tuple is a collection which is ordered and unchangeable. String is a type of value that can be stored in a variable.

DATATYPES: 1. none: when a variable is declared but does not tag to any value, that variable is said to have 'none' datatype. 2. numeric: numeric datatypes deal with the numbers and its family. 2.1 int- integer 2.2 float- floating point 2.3 complex- complex numbers 2.4 bool- boolean 3. Sequence: it deals with the data entered and maintained in the form of a sequence. 3.1 LIST [ ] 3.2 TUPLE ( ) 3.3 SET { } 3.4 RANGE ( ) 4. Mapping: It deals with the values which are mapped to a unique key for accessing. 4.1 Dictionary { }
