Python Tutorial for Beginners 15 - Classes and Self

In this Python Tutorial for Beginners Video, I am going to show you how to Create and Run Your First Python class. In Python, everything is an object i.e. integers, strings, dictionaries, …
Class objects are instantiated from user-defined classes, other objects are from language defined types. Classes In python Can be defined anywhere in the program. In this video I am going to give you two Python Class examples.

I liked most of your videos, but this one is particularly confusing

[maratyla]

So as I understand: Class is folder of defs, and self is access for other scripts to use functions inside the class even if scripts outside the class

[bgilbert]

Reviewed several tutorials on python classes and thought this was one of the best

[inesborges]

Wouldn't it be simpler and easier if I just write a function to print the name of a person?
The result is the same. Why should I use 'self' and define a class?

def person(firstName, lastName):
print(firstName, ' ', lastName)

[bhargavshah]

All of your videos are awesome man but this video is so much create confusion !!

[shivamjha]

I am very sad please help me with undrstanding this concept class I have tried too many times but always failed

I am 9 year old trying too understand please Is there anyone who can help me

[markwiygul]

thanks for posting about methods and attributes

[rockyrock]

u tried it good but if a newbie will watch it to get understand your concept sure he will get confused so record it again

[johnpauledrittbinay]

I am a super beginner at Python trying my best to understand the world of computer programming and I am honestly flummoxed and bewildered by the concept of "class". I'm sure for some this part of the tutorial may prove to be useful, but that wasn't the case for me....it's my fault, not yours. If you can explain this video in a different way or give me a link to a document/video regarding this topic that would be very helpful

Thank You So Much!

-im 15 in the ninth grade, if that's any indication of my aptitude in comp. programming. However, I did understand your previous videos perfectly, but just not this one!

WHATS THE NEED OF SUCH A HUGE
I can do the same thing what you did in just two lines -

def abc(firstName='programming', lastName='knowledge'):
print(firstName, lastName)






now just run it and in the py shell just write -
abc()
it will give the the output - programming knowledge (i.e the first and last name)
#you can also overwrite the name above by giving another first and last name in the argument


so what's the need of classes('you haven't explained it prooperly for a beginner)

[nurmohamad]

can I use functions in array as used in a class and call them?

[SureshKumar-uctz]

Sir, That self, need not be always self right, we can use any other word ?
Is it possible to create any function without that self also ?

[arminyz]

Not good at all, record it with a better explanation and explain more precise. This tutorial makes a beginner more confused about Class and Self in python

[md.shorifulislam]

After showing your video, I tried but can't" . Where is the mistake I made:
class Person :
def setFullName(self, firstName, lastName):
self.firstName=firstName
Self.lastName=lastName
def printFullName(self):
print(self.firstName, "", self.lastName)

PersonName=Person()
, "Knowledge")
PersonName.printFullName()

[tarasensemble]

Confusing. since it is for beginners. It would be good if you would have overviewed the what is a class, object and its purpose.

[ramakrishna]

sir i got an error like this will you explain it for me (Traceback (most recent call last):
File "C:/Users/user/AppData/Local/Programs/Python/Python39/class.py", line 7, in <module>
personName=Person()
NameError: name 'Person' is not defined) please sir

[ericbridge]

What does self do? You didn't make any variables in the class. What is the difference in using the variables with self, amd then without it. Cause sinse they are just the parameters of a method, they exist only in that method. So it means that the other method Shouldn't be able to use it. You didn't declare them as global, did you?

[emzyvines]

should be done with precise and toke good stuff which is easier for the audience

[pushparay]

Why didn't u use the id in the destructor function? But you printed it there. Why did this happen?

[MrVineet]

great job, very easy to understand !!!
