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.

im on my final year of undergrad mechanical engineering and this covid19 stay at home got me so bored.....then boom I decided to learn coding and I found this channel. Good heavens!
If you're interested in computers, why didn't you chose software engineering/computer science.
@@harshakampli2760 well lets just i realized that im more interested in computer 5 years too latee.....
@@ninoangelobacayo67 oh, it's okay😁
@@harshakampli2760 the thing is nowadays coding is an important skill for engineers belonging to any discipline. From developing excel spreadsheet to running simulations of aerospace models, a knowledge of coding is required to get the job done
@@kamalbhaizan oh ok. Thanks for that.
none = a variable with no assaigned value
list=[ a group of mutable values]
tuple=(a group of immutable values)
set= {a group of none repeating valuves}
range=(series of values that can be expressed using end values)
mapping={storing values uses keys instead of indexing}
Excellent
Table ni smjh aa rha kya matter hai bro table ka .can u tell me pls
Good!
TQ Abhi👍
instead of mapping it is better to say "dicationary" bro, rest is well.👍
Sir you are like an angel for computer engineer 😘
Even for mechanical engineer
even for an electronic engineer
I.T
Even for a commerce graduate
Even for 11th student
Watched 11 videos of python course and I can't thank you enough for these classes! Great explanations and insights, making the learning experience fun and fast. Thank you so much for your generosity!!
Sir you are just amazing
You make me confident that i can learn python
Thank you sooo much
I never saw a teacher like you !!!! U r explaining the concept clearly ; Thank you so much ...........
The way you teach is amazing mate, I'm loving my Python learning journey.
I actually love how you are taking through the series for people who know other languages and letting them not confuse with python.
OMG Python looks child's play in front of C 😂
No.
The way you explain it's damn easy to understand and video editing is BOLE TO #JHAKKASS..
BOLE TO POORA JHAKAAS
Integer :- a whole number value
Float :- a decimal value
String :- a text
Character :- special symbols
numeric types right??????.... asked data types none,numeric,list,tuple,set,range,string,map(dictionary)
i know u r smarter now, because its 4 years now..... 😁 sry for what i said, just replaying to your comments thats all
following this series & this is great, short time;more learning!
Yes Sir...I'm enjoying your tutorials a lot.
Your way of teaching is very simple, effective and interactive.
1- *string* = 'used to store text' e.g: *'navin'*
2-*float* = 'used to store decimal or fractional values' e.g: *2.69*
3-*integer* = 'used to store non-decimal values' e.g: *7*
4- *character* = 'used to store symbols' e.g: *@*
not only symbols i think.character = symbols + alphabbets+numbers in foem of name
There is no character in python...even a single letter is considered as a string
No character in python
Yes no character in python
Just started. Hoping to get most of it. Telusko has done a great job. Thanks.
I am a complete noob to coding and computer science. This guy makes it easy to understand and learn. thanks for all the hard work and dedication to making these awesome videos! You sir are an angle!
p.s.
when I get my first programming job I will donate to this guy in recompense.
Hi mate, have you got your first job, and how it’s going
You are simply amazing
Really loving this python session
Thank you so much for this...
Keep progressing😇
Im in love with ur work... thankzz sir💕 from sri lanka
Hi Navin.. The way you approach towards the concept is literally awesome. Please do some videos on Python API's too. It would be helpful for us.
Very simple and easy lectures, hands-off to you, great work, u made programming easy to understand and learn
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
Amazing lessons and way of delivery. I am mechanical engineer in my mid career. Your videos are enhancing my interest towards coding. Hope I will be a good coder in future and will be thankful to you always. More power to you. Keep up the great work. You are awesome.:)

Your are giving great effort for us. Tnx very much Reddy sir
This is by far the best Python tutorial in CZcams
Enjoying the series a lot. Lots of respect from Bangladesh
Great explanations and insights thank you so much bro.
Data type-->int, float, string, range, list, tuples, set etc
Thank you for your great tutorial videos. I am finding them quite helpful so far. Just wanted to ask a quick question, would you be discussing unary operators in your next videos?
Great person you are. I was in dilemma regarding the required stuffs for python. Now I am gaining Momentum. Love ❤❤ from NIT! 🙏

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
great teacher best videos ever!!!
A very good teacher you are ! I love the way you explain all the concepts!!
see jay sharma python he is also study python
see , how people are selfish bcoz the views on this video are 7.5 lakhs and likes are only 12k
😂
I don't understand why do our institutions teach us C++ instead of Python as introductory course to programming, python is such an amazing course though? I think python could not be so easy but the way of teaching the Sir makes it so, thank you sir for your efforts.
because C++ has better operational advantages / projects coming than Python
