[00:00:00]  Hi, K.
[00:00:00]  Lakshmikar.
[00:00:02]  Hi, sir.
[00:00:04]  Can you please quickly introduce yourself, please?
[00:00:07]  Sure, sir.
[00:00:08]  My name is K.
[00:00:08]  Lakshmikar.
[00:00:09]  I am from Kadapa.
[00:00:10]  I completed my B.Tech graduation in SBC College, Tirupati.
[00:00:13]  Recently, I worked as a Python developer in Varian Software Solution.
[00:00:17]  My role is to develop the RFQ functionalities.
[00:00:19]  It is fully dependent upon the backend side.
[00:00:22]  In that, I use technologies such as Python, Django, ERP Next, and MySQL.
[00:00:29]  The main theme of this project is it is one type of e-commerce website where normal products, pharmacy products, everything is present in that digital mall project.
[00:00:39]  For example, take Flipkart, Amazon, everything.
[00:00:42]  In that websites, we have only particular products, not pharmacy products.
[00:00:47]  For digital mall product, it is having both pharmacy products and normal products.
[00:00:50]  This is the advantage for this digital mall application.
[00:00:54]  First of all, I am running a hospital.
[00:00:56]  I want medicines.
[00:00:58]  I need to buy medicines from the pharmaceutical company.
[00:01:00]  I need not to go to the pharmaceutical company.
[00:01:02]  I just go to the digital mall application and I generate RFQ quotation for this item.
[00:01:08]  I want these items and this is the cost price.
[00:01:12]  This is the discount.
[00:01:13]  Everything is present in RFQ quotation.
[00:01:16]  Based on that RFQ quotation, they deliver the medicines to the hospitals.
[00:01:20]  This is the concept of digital mall project.
[00:01:23]  After that, I implemented my own project called MealMate project.
[00:01:27]  It is related to the Swiggy type project.
[00:01:31]  The main motive of this project is I just know how much knowledge on these technologies I can learn from the company.
[00:01:40]  I just implemented what are the technologies used in my previous company.
[00:01:44]  I just implemented in my own project, meal-made project.
[00:01:47]  In this, I use Python, Django, MySQL.
[00:01:52]  I use these three technologies to build a meal-made project.
[00:01:57]  You can open the meal-made project, you can select the food items, you can add into the cart and you can pay amount through Razorpay API integration.
[00:02:09]  Based on this, we can order the food.
[00:02:15]  Okay.
[00:02:16]  Okay.
[00:02:16]  So can we quickly dive into the technical round?
[00:02:20]  Can you share your screen and open any Python compiler?
[00:02:26]  Okay.
[00:02:56]  So you know, you have knowledge on pandas?
[00:03:00]  Sir, I have theoretical knowledge, but I don't have practical knowledge on pandas.
[00:03:04]  I know what pandas is.
[00:03:07]  How can we read the files?
[00:03:08]  How can we write the files in pandas?
[00:03:12]  The basics I know, but I don't know the implementation.
[00:03:15]  Let's see.
[00:03:16]  We will ask you about basics of data frame creation.
[00:03:22]  Okay.
[00:03:22]  We'll see.
[00:03:24]  So let's suppose you have one file.
[00:03:27]  Okay.
[00:03:27]  And you need to read a data frame out of it.
[00:03:31]  How will you do it?
[00:03:32]  Consider it being CSV file.
[00:03:36]  What to say?
[00:03:38]  Read underscore CS, I mean, import Python.
[00:03:41]  pandas as pd, pd.read underscore csv of that file name.
[00:03:46]  We can read that file, sir.
[00:03:49]  Okay.
[00:03:50]  Okay.
[00:03:50]  Fine.
[00:03:51]  So write a function, okay, which will accept two lists.
[00:04:00]  Okay.
[00:04:02]  Sir, write a function which will accept two lists.
[00:04:06]  Okay, one list will have, so list is expected to have numbers.
[00:04:10]  Both the list should be expected to have numbers.
[00:04:13]  For one list, you need to square them and then add it up.
[00:04:18]  And the other one, you need to cube each number and then add it up.
[00:04:22]  Okay, but you have to do this using list comprehensions.
[00:04:27]  Okay.
[00:04:29]  Yeah.
[00:04:33]  And you have to return both the values outputs and then print at the end.
[00:05:40]  I'm sure.
[00:07:57]  The values that you are sharing, right?
[00:08:00]  A, 1, 2, 3, 4, 5.
[00:08:02]  They should be out of my function.
[00:08:03]  I need to pass them as an arguments.
[00:09:13]  Let me know if you are not clear, we can move on to other questions.
[00:09:16]  All right, sir.
[00:09:17]  Just a minute, sir.
[00:10:00]  Can you please explain me what you are trying to do?
[00:10:03]  Sir, in the function I am giving the argument, after that I am taking the input as a list input.
[00:10:16]  For that I can multiply one by in that result.
[00:10:19]  It will show the square of each number.
[00:10:27]  So, I mean, first of all, did you understand the requirement?
[00:10:30]  Can you please give me an example?
[00:10:35]  Sir, I understand.
[00:10:40]  In that list, I can find the square of each number and I should add the squares.
[00:10:48]  Yeah, not only for one.
[00:10:50]  So you have two inputs.
[00:10:52]  For one list, you need to do square of each element.
[00:10:55]  Let's say one square, two square, three square and then add three of them.
[00:10:59]  And for the other one, it is one cube, two cube and three cube and then add all of them.
[00:11:05]  Yes, sir.
[00:11:07]  And both the results should be from your function output.
[00:12:26]  N is a number.
[00:12:29]  Okay.
[00:12:30]  And you're trying to loop on a number.
[00:13:08]  Okay, we'll move on to the other question.
[00:13:10]  Okay, that's fine.
[00:13:13]  So let's say I have initialized A and B with 5 comma 6.
[00:13:19]  Okay.
[00:13:21]  Can you swap it?
[00:13:25]  Let's say now A should become 6 and B should become 5.
[00:14:18]  Is there any single line function, I mean single line statement which will does that?
[00:14:30]  Without using TARD variable, we can perform XOR operation to swap these numbers.
[00:14:37]  Not even that complex, it is very simple.
[00:14:46]  So can we initialize same or let's say multiple variables in a single line?
[00:14:51]  Let's say you have initialized a equal to b, let's say a equal to 5, b equal to 6.
[00:14:56]  Can we initialize in a single line?
[00:14:59]  Yes, sir.
[00:15:13]  Okay.
[00:15:15]  So now what will happen if I give a command a comma b equal to b comma a after your third line?
[00:15:26]  B comma.
[00:15:29]  A comma equal to B comma A.
[00:15:37]  Remove other lines.
[00:15:38]  You can directly print the icon.
[00:15:51]  So this is a single line statement.
[00:15:55]  Okay, I have a dictionary.
[00:16:00]  Okay, which has, let's say, ABC as a piece and one, one, two, three as values.
[00:16:09]  I have one more dictionary, which has a DEF and then four, five, six as values.
[00:16:18]  How can I merge both of them into single one?
[00:16:39]  And two dictionaries, you need to mention two single dictionaries.
[00:16:45]  Yes, we need to merge into single external.
[00:18:50]  You need to merge two dictionaries.
[00:19:08]  So it should be combined additionally where it will say that A1, B2, C3, X2, Y3, Z4.
[00:20:02]  So let's say, take one variable, which is, let's say your name.
[00:20:09]  Okay.
[00:20:12]  I need you to identify how many number of vowels are there part of your name.
[00:20:22]  Can you help me with one thing?
[00:20:23]  Like, can you remove your earphone and then talk directly?
[00:20:31]  I mean, we generally don't accept earphones.
[00:20:33]  Just saying.
[00:20:34]  Okay, sir.
[00:20:43]  Sir, one minute sir, I can switch off the fans.
[00:20:45]  It won't listen.
[00:20:49]  You are audible, you are audible, not a problem.
[00:21:14]  I need to find how many ovals or how many consonants in that string.
[00:21:19]  Ovals only.
[00:21:23]  How many number of whales are there?
[00:21:25]  You need to find out.
[00:21:30]  Yeah, can you hear me?
[00:21:37]  Hello.
[00:21:40]  Am I audible?
[00:21:44]  You might need to increase your volume.
[00:21:56]  Hello?
[00:21:57]  Hello?
[00:21:59]  Am I audible?
[00:22:01]  Sir, I'm unable to hear your voice.
[00:22:11]  Hello?
[00:22:22]  Sir, I already increased the laptop.
[00:22:26]  Volume, sir.
[00:22:26]  It's 100.
[00:22:30]  Hello?
[00:22:36]  Hello, can you hear me now?
[00:23:19]  Hello?
[00:24:08]  Hello.
[00:24:10]  Am I on?
[00:24:10]  Sir.
[00:24:11]  Yes, sir.
[00:24:13]  Okay.
[00:24:14]  I think some problem with your system.
[00:24:26]  So you need to identify all the list of ovals.
[00:24:31]  Okay, sir.
[00:24:33]  Count of over, sorry.
[00:27:27]  Ça.
[00:27:37]  So write a function.
[00:27:40]  Okay.
[00:27:42]  Which will accept
[00:27:46]  number and an optional optional number.
[00:27:49]  Okay, optional value optional argument.
[00:27:52]  Okay, and if that optional argument is given, it will cube the number and then add it add it to that particular number.
[00:28:00]  If optional number is not given, then it will directly square the number and then return the output.
[00:28:11]  Can you repeat once again?
[00:28:14]  So write a function which will accept two values.
[00:28:18]  One is mandatory, the other one is optional.
[00:28:20]  Okay.
[00:28:22]  If that optional one is not, let's say value is not given, you need to square the number and then return output.
[00:28:29]  The optional number is given, you need to cube the number and then give me the output.
[00:29:39]  Sir, but this I have no idea what optional argument.
[00:29:45]  Okay.
[00:29:49]  So can you write the Fibonacci series code?
[00:29:53]  Focus.
[00:31:11]  So I have the previous interviewer also with me.
[00:31:17]  So yesterday you communicated everything orally, right?
[00:31:19]  Why are you not able to write those functions or anything?
[00:31:25]  Sir, mostly I mean I didn't write any functions code.
[00:31:34]  Just I go through with the normal input type of functions.
[00:31:38]  In my previous company, I just look on, okay, they are already given that code.
[00:31:43]  I can see, okay, this is the functionality.
[00:31:46]  Okay, in that functionality, what type of errors it is present.
[00:31:49]  I can identify that errors.
[00:31:50]  I can fix that errors.
[00:31:52]  For that, already there is an existing functionalities, no?
[00:31:57]  So based on that functionality, I can develop the whatever.
[00:32:01]  It is a basic one.
[00:32:02]  As part of your Python basics, function is a first.
[00:32:06]  One of the important component that you need to learn.
[00:32:15]  I mean, you are going to this next wave, right?
[00:32:20]  So, it should be part of your curriculum, I guess.
[00:32:24]  How many days since you started next wave, let's say, starting learning?
[00:32:30]  BTEC third year, sir.
[00:32:34]  So you are currently B.Tech third year or from B.Tech third year you are learning?
[00:32:37]  No, no, no.
[00:32:38]  From B.Tech third year I am learning.
[00:32:42]  Okay.
[00:32:46]  So currently you're BDEC passed out, right?
[00:32:48]  Yes, sir.
[00:32:57]  Okay, I think, yeah, that's it, Lakshmika.
[00:33:00]  Do you have any questions to me?
[00:33:03]  No, sir.
[00:33:04]  Okay.
[00:33:05]  Yeah.
[00:33:05]  Thanks for joining the call.
[00:33:07]  Okay, sir.
