Lab 1 :
Print Hello World
print("hello world")
a = 'hello world'

  print(a)


Lab 2
Variables in Python
a = "my first variable"

  print(a)
 
b =  100
 print(b)
  

c = 10.50
  print(c)


Lab 3
Arithmetic Operation in Python
# getting the numbers

  
  a = 1
  b = 2
  c = a + b

  print(c)


  print("Answer is ", c)
  

  # printing the values into mutiple time

  demo = "Demo \n"

  print( demo * 5)
  

  #getting the square values

  square = 2 ** 3

  input("get the value")

  print(square)

  

  # getting the divisions

  

  d = 8/3

  print(d)

dd = 8//3

  print("division vaues",dd)

  

  # input values in the Python

  

  num1 = input("Enter the value of 1  num :: ")

num2 = input("Enter the value of 2 num :: ")

print("Addition of two values " ,int(num1) + int(num2))

  

  ##   pre  conversion

 num3 =  int(input("Enter the value of 3  num :: "))

num4 = int (input("Enter the value of 4 num :: "))

  print("Addition of two values "  ,num3 + num4)


Lab 4
Conditional Statement in Python
# conditional statement

#print( 8 & 1)

'''

muti line Commented values

'''

'''
#Using if if and else 

num  = int(input("Provide the number : "))

if(num & 1) == 0: #indentation

    print("Even Number")

else :

    print("Odd Number")
 
'''


  

  # if else ladder


  a, b, c = 2, 1, -8
 

  if a> b:

    if a > c:

        print("a is bigger")

    else :

        print("c is bigger")

  

  else:

    if b > c:

        print("b is bigger")

    else:

        print("c is bigger")

  

  # make it same line of condition

  print("_" * 20)

  

  if a> b and a > c:

    print("a is bigger")

  elif b > c:

    print("b is bigger")

  else:

    print("c is bigger")

  

  

  # programme to calculate leap year


  lp  = int(input("Provide the year : "))

  if (lp % 4) == 0:

    print(lp, " is Leap Year")

  else:

    print(lp, " is not Leap Year")



Lab 5
Loops in Python. While, for,
# Loops

'''
i = 1

while i < 100 :

    print (i)

    i += 1

'''

  

# print  even number till 100


  j = 1

  while j < 100:

    if (j % 2) == 0:

        print (j)

  

    j +=1


  x =0

  for x in range(0, 3):

    print(x)

name = "This is the required document"

  list3 = ["A", "E", "I", "O","U"]

count = 0

  for i in name :

    print(i)

    if  i.upper() == 'A' or i.upper() =='E' or i.upper() == 'I' or i.upper() == 'O' or i.upper() == 'U' :

      count = count + 1

  

  print("No of Vowel =", count)


Lab 6
Jumping Statement in python
# Jumping statetemnt

  '''

Break

Continue

Pass

'''

'''

num =40

if num >1:

    pass

while num >1 :

    num =  num - 1

    print(num)

    if num == 38:

        break

    else:

        continue

  

'''

  a = [0, 1, 2]

element = 0

  for element in a:

    if not element:

        pass

        print(element)

  

  for element in a:

    if not element:

        continue

        print(element)


Lab 7
Datastructure in python,  python contains four  types of collection datatype  List, Tuple, Dictionary , set
'''

List : collection of element contains homogenues and hetrogeneus, denoted by []

tuple : denoted by ()

dictionary : denoted by {}

set

'''

## List

  a =[]

b = [1,2,3,4,5,6,7,8,9]

  print(b)

b.reverse()

  print(b)

b.pop()

  print(b)

b.append(8)

  print(b)

b.insert(3,6)

  print(b)

b.sort()

  print(b)

  print(b.count(8))

a.append("Hyderbad")

  print(a)

a.append("Delhi")

  print(a)

c = [1,2,3]

c.extend(a)

  print(c)

  print(len(c))

  

d = c.copy()

d.append("dest")

e= c

e.append("New")

  print(c)

  print(d)

  print(e)

  

  

  # slicing in data structure

  

  print(b[:2])

Lab 8
Formatting the String  function for print
# format function using the print command

  a,b,c,d = 1,2,3,4

  

  print("a = ",a, "b =", b, "c = ",c ,"d =", d)

  print("a = {}, b = {}, c = {}, d = {}".format(a,b,c,d))

  print("a = {0:.1f}, b = {1:d}, c = {2:b}, d = {3:^5}".format(a,b,c,d))

  print("a = {0}, b = {1}, c = {2}, d = {d}".format(a,b,c,d = "satya").capitalize())

  print("a = {0}, b = {1}, c = {2}, d = {d}".format(a,b,c,d = "SATYA").upper())


Lab 9
Function demo in Python
# using of function

  

  def myevenodd(val = 26) :

    if val == 26:

        print(val, "default function call")

    elif val % 2:

        print(val, "It is even number")

    else :

        print(val, "It is odd number")

  

  '''

val = int(input("Enter the number : "))

    print(val, "It is odd number")

else :

    print(val,  "default function call")

  

  

v = 1

print("Even value")

for  v in range(1,101):

    myevenodd(v)

  

'''



Lab 10
Implementing inbuilt function of python
a,b,c,d = 10,20,30,40

  

  # Inbuilt Min and max function

  xx= max(a,b,c,d)

xm= min(a,b,c,d)

  print(xx)

  print(xm)

  print(a,b,c, d)

  

  

  # power functions

  

  pp = pow

  

print(pp(3,3))

  

p = pow(2,3)

  print(p)

  

  


Lab 11
Importing math functions in python
import math

  

  def reverse_number(val):

    res = 0

    while val > 0 :

        rem = val % 10

        res = (res* 10) + rem

        if val > 0 :

           val = val // 10

  

    return res

  

  def adon_number(num):

    #print("num", num)

  

    square =  num ** 2

    #print("square", square)

  

    rev1 = reverse_number(square)

    #print("rev1", rev1)

  

    mysqrt = int(math.sqrt(rev1))

   # print("mysqrt", mysqrt)

  

    rev2 = reverse_number(mysqrt)

    #print("Adon number", rev2)

    return rev2

  

x = 1

  for x in range(1,1000):

    op = adon_number(x)

    if op == x:

        print(x, " is adon number")
