   Sir in your teaching techniques is very technical and just realised you to something me it's good for understanding thanks and bye baii

2. 

   Love you 3000😍

3. 

   make series of videos on Data structure and algorithms

   Why your hair is greenish ?

5. 

   from array import *

   a= array('i',[5,54,1,5,8,7,30,45])

   for i in range(len(a)):
   
   for j in range(len(a)):

   if a[i]<a[j]:
   
   a[i],a[j]=a[j],a[i]

   print(a)

6. 

   Hii sir..@13:24 you used array(Val's.typecode, (a for a in vals))

   Isn't it necessary to end a for with : ??

7. 

   The only thing I didn't get it is why not just write:
   Array1 = Array2 –> This give you another array with the same values as the first, no?

8. 

   from array import *
   
   arr=array('i',[2,4,5,7,0,1,6,2,4,5])
   
   arr1=sorted(arr)
   
   print(f"{arr} after sorting{arr1}")

9. 

   "But you can use while loop"

10. 

    from math import *
    
    x = int(input("Enter the number that you wanna factorial : "))
    
    print(factorial(x))

11. 

    from array import *
    
    array = [45,65,76,78,89,43,44,56]
    
    array.sort()
    
    print(array)

12. 

    import array as arr

    x = arr.array('i',[5,4,3,2,1])
    print("before sort:",x)
    k = 0
    
    for e in range(5):
    
    for e1 in range(5):
    
    if e > e1:
    
    e,e1 = e1,e

    k+=1
    
    print("n after sort:",x)

    Great Job..! Very helpful..!

    1st answer
    from array import *
    
    vals= array ('i',[5,9,8,4,2])
    
    for i in range(len(vals)):
    
    for j in range (len(vals)-1):
    
    if vals[j]>vals[j+1]:
    
    temp=vals[j]
    
    vals[j]=vals[j+1]
    
    vals[j+1]=temp
    
    print(vals)

    2nd answer
    from array import *
    
    vals= array ('i',[5,9,8,4,2])
    
    x=int(input("Enter the element you want to find : "))
    
    for i in range(len(vals)):
    
    if vals[i]==x :
    
    print("Element found")
    
    break
    
    else :
    
    print("Element not found")

    Palindrome in python how to do this programming

16. 

    since we have list (builtin class) whats the need for array in python?

17. 

    Superb. I have never seen so attractive way of learning. Thanks alot 🙂 🙂

18. 

    #1
    From array import *
    v=array('i',[9,3,5,6])
    x=sorted(v)
    for e in x:
    Print(e)

    #2
    Import math
    V=int(input ("enter a number"))
    Print(math.factorial(V))

    sir ur assigment question is not properly visible due to Telusko Logo..

20. 

    you are to good

21. 

    First:-
    from array import *
    values = list(array ('i',(2,5,3,7,1)
    val.sort()
    for i in val:
    print(i)

    Second:-

    val=6
    i=1
    c=1
    while i<=val:
    c=c*i
    i=i+1
    print("Factorial =",c)

22. 

    import math
    
    from array import *
    
    vals = array('i',[1,2,3,4,-2])
    
    newarr = array(vals.typecode,(a*a for a in vals))
    
    for i in range (len(newarr)):

    print(vals[i])
    enen this above couldn't fetch the square vals of vals
    please help!!

23. 

    Navin sir, to get duplicate can I use –> newArr=vals[:] ?

24. 

    how to user input the array

25. 

    every beginner needs u only…waste of money & time by joining coachins….

26. 

    I love your teaching skills(pls become my home tutor )
    😀

    For factorial of a number
    x=int(input('Please enter your number'))
    
    j=i=1
    
    while i<x+1:
    
    j=j*i
    
    i=i+1
    
    print(j)

28. 

    sir could you suggest me a book by indian author for learning python and also if i use function id and pass array as a argument i get different address as compared when i use function buffer_info on array i get diffrent address

29. 

    for factorial
    n = int(input("Enter no. to find factorial:"))
    f = 1
    for i in range(n):
    f = f * n
    n-=1
    print(f)

30. 

    import array as ar

    vals = ar.array('l',[21,35,21,52,53,96])

    print(vals)

    print(vals.buffer_info())

    print(id(vals),len(vals))

    '''result: array('l', [21, 35, 21, 52, 53, 96])
    
    (115130180272, 6)
    
    115130124784 6'''
    please explain why id is different .
    thank you

    Thank you Navin Reddy for the amazing python series.
    Code to find out factorial of given number.
    x = int(input("Enter a number:"))
    
    #
    
    temp = x
    
    #
    
    if x > 1:
    
    for i in range(1,x-1):
    
    a = temp * (x-i)
    
    temp = a
    
    print("Factorial of ",x,"is ",a)
    
    else:
    
    print("Factorial of 0 or 1 is 1")

    Note: if we follow this logic, then iteration would be (x-2) times. But if we use index to find factorial like fact=fact*i, the iteration would be x times.
    Please correct me, I am not efficient.

    Hi Navin, when copying array content from vals to newArr , we could have simply assigned. newArr = vals. Am I missing something here.? Or would there be any issue in real time programming ?>

33. 

    Hi sir your explanation is so nice.

34. 

    Thanks so much sir❤❤
