  1. 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. make series of videos on Data structure and algorithms

  3. Why your hair is greenish ?

  4. 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)

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

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

  6. 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?

  7. 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}")

  8. "But you can use while loop"

  9. from math import *

    x = int(input("Enter the number that you wanna factorial : "))

    print(factorial(x))

  10. from array import *

    array = [45,65,76,78,89,43,44,56]

    array.sort()

    print(array)

  11. 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)

  12. Great Job..! Very helpful..!

  13. 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")

  14. Palindrome in python how to do this programming

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

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

  17. #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))

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

  19. 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)

  20. 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!!

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

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

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

  24. 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)

  25. 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

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

  27. 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

  28. 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.

  29. 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 ?>

  30. Hi sir your explanation is so nice.

  31. Thanks so much sir❤❤
