00:00In this lecture, we have thoroughly discussed if, alif and else.

00:03In this lecture, we have two other keywords introduced to us.

00:08The first keyword is and, and then the second keyword is and.

00:15This is our keyword.

00:16We have to keep our keywords in our own mind.

00:18Now I will tell you what to say about this.

00:22Imagine that this is our previous story, Tom and Jerry.

00:26Okay, now imagine that this story in a while is the owner of the dog.

00:36Imagine that the dog is true.

00:37At the moment.

00:39Now, the question is that cat and dog are both together.

00:45Okay, now I will tell you that cat and dog, when someone exists,

00:54if you want to do it, then you want to do it.

00:57It's like that.

00:59Now, can I have two conditions in one condition?

01:03One condition in one condition?

01:05This is the answer.

01:07Yes, yes.

01:08And the two things combine to do it.

01:11It's either I can combine it or I can combine it,

01:15or I can combine it.

01:17Okay.

01:18Okay.

01:19First of all, I will show you the barebone structure.

01:22I will print the statement.

01:25I will say print true.

01:28Right?

01:29Now, we will execute it.

01:31I will remove it.

01:33Okay?

01:34Why, I will show you the deep barebone structure.

01:37Print true is true.

01:39is true, right, print false is false, no problem, yeh toh bhot hi asan hai na, halwa hai, yeh

01:47toh hume pata hai ki print false karo hoon toh false hi hai ga na, or yeh false keyword

01:51false hai, accha, however, agar mein kehta hoon, ek condition, let's say, ek value hai

02:00true, lekan usko combine karne laga hoon a keyword ke saath, and, aur phir, mein keha

02:06raha hoon true, right, ab agar mein isko print karta hoon, toh yeh keha raha true, ab basically

02:14ho kya raha hai, yehaan peh doh conditions aah gai hai, true and true, aur and ki khasiyat

02:20yeh hai, ke and wo, wo nye hota jaisa ke wo, apne dekha hooga, kanun ananda hota ho, hat mein

02:26doh pakde hootay hain, wo, wo jo hootay hain, yaar, wo, tolne wale, something like this,

02:33yeh is tarah ki chiz, apne dekhi hooghi, aise iske saath hootay hai, dousera iske saath

02:37aise hootay hai, and you see like, something like this, sahi hai, aise chiz, ab jo and

02:44key word hai na, wo iski tarah hai, aur and kehatta hai, ke mein usi wakt te dounou level ko

02:51balance ruk karun ga, jab dounou meire paas true hoonge, meire left or right pe, true and true,

02:57tbhi mein execute karun ga code ko, and ke saath left or right pe, jab true hoongi

03:07dounou statement, tbhi yeh true return karega, otherwise yeh false return karega, agar

03:12isme se ek bhi false hojati hai na yeh, to douseri ki kooi masala nahi hai, woh kaya ga

03:17ho, yeh false hai, I don't accept it, chalye yeh, mein aapko yeh karke dikhaatau, it's very important,

03:22important, uski reason yeh, ke jab hum, yeh, dhekheye, mein isko kata, isko run kerte

03:26hain, ab dhekheye, false hojaya, kyun, kyunke end ke liye, dounou statement, uske left

03:31or right pe, true hoonga, however, joh or hai, aur keyword, woh bhot lenient hai,

03:38isso walhe se, woh kata, yaar, meire liye, agar true return karna hai na, to koji

03:42ek bhi true hojai, meire left ya right pe, mao isko true kar dunga, ab dhekhe, mein isko run

04:13ke, yeh statement execute honi chahiye, chahe, in mein se koji ek true ho, chahe,

04:22ek, to yeh or ka case hai na, or true return karta tha, chahe, in mein se ek true ho, to

04:27agar, mein kaya deta hoong, aur, to basically, mein yeh likhaa hoong, is case mein toh

04:30dono true hai na, dono true hai, to true hai, however, is case mein agar

04:33mein false kar dieta hoong, dog ko, to basically, mein kya kar raha hoong, basically,

04:36mein yeh kar raha hoong, true or false, yeh kar raha hoong, to aur kya karta hoong,

04:43wo kata hai, yeh, chahe, dhono, meire left, right, peh, ek bhi, agar true hoong gai,

04:46to, mein true return karunga, to basically, wo kya karayega, yeh, peh, true return

04:50kar dhega, f dhekhega, if dhekhega, ke, meire saamne toh true hai, agar meire saamne

04:55true hai, wo kyega, mein isko execute karta hoong, no matter what, to, ap dhekhiye,

04:58mein doobara karta hoong, right, eek true, eek false hai, execute kiya, mouse run away,

05:04thik hai, kyun, kyun, kyunke, ya, kutte mein se, ya, billi mein se, koi bhi eek hooga,

05:09to, mouse run away ho jayega, thik hai, however, agar mein yahan peh end

05:14kehta hoong, to, dhono ko, ikathe, mوجود hoona, chahehe, tab, chuha,

05:19dhođe ga, otherwise, chuha, nahi dhođe ga, thik hai, ab dhekhiye,
