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]) print(b[2:6]) print(b[1:6]) print(b[5:2]) m = [1,2,3,4,5,6,7,8,9] print(m[3:6]) # 7 - 4, 7 - 1 print(m[-4:-1]) print(m[::2]) print(m[::5]) print(m[::1]) print(m[::-1]) print(m[::-2]) print(m[1::-5]) b = "Hyderbad" print(b[::-1]) a = 12345 ar = str(a) print(int(ar[::-1]))

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 : ")) if myevenodd(val) == True:     print(val, "It is even number") elif myevenodd(val) == False :     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")
