1. Verify if the given string is palindrome

12.check for palindrome

s= input('enter the string\n')
l = list(s)
l.reverse()
n1 = ''
for i in l:
    n1 = n1 + i

if s == n1:
	print('given value is palindrome\n')
else:
	print('not a palindrome\n')


2. Find the highest ascii value in a given string

st = input()
n = max(s)
print(ord(n))

3. Print true if the given sentence ends with a "holiday"

sentence = input('enter the sentence\n')
if sentence.endswith('holiday'):
	print('True')
 

4. Unicode value of a given string

name = input()
for i in name:
	print(ord(i))


5. Given input string, add 4 spaces in the end and use full stop in the end.

s = input('enter the input string\n')
l = list(s)
l.extend([' ',' ',' ',' ','.'])
st = ''
for i in l:
	st+=i
print(st)


6. Convert given string into list in one line: e.g., "hello world" output = ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']

lis = list("hello world")


7. Find the sum of elements in the list e.g., [10,20,30] output = 60

l =[10,20,30]
print(sum(l))


8. Duplicate the elements in the list e.g', list1 = [1,2,3] output = [1,2,3,1,2,3]

list1 = [1,2,3]
print(list1*2)



9. Find the greater of two lists list1 = [1,2,3] and list2 = [1,2,3,4]

list1 = [1,2,3]
list2 = [1,2,3,4]
if list1>list2:
	print('list1 is greater\n')

else:
	print('list2 is greater\n')


10. What are help() and dir() used for?



11. Write a python program to print prime numbers between 100-300

def prime(num):
    for i in range(2,(num//2)+1):
        if num % i == 0:
		return False
    return True

def primenos(n1,n2):
    for i in range(n1,n2+1):
        if(prime(i)):
            print(i)
primenos(100,300)


12. 1. Find the common elements between two lists without duplicates.
a = [1,2,3,2,4,5,6,7,8]
b=[1,2,4,10,11,12]
output: [1,2,4]

l=[]
for i in a:
	if i in b:
		l.append(i)

print(list(set(l)))



13. Find the word reverse of a given sentence.
input = "my name is virat kohli"
output = "kohli virat is name my"

lis = input.split()
lis.reverse()
for i in lis:
	print(i,end=' ')



14. Join list a (as keys) and list b (as values) to make a dictionary in one line.
a = ["key1", "key2", "key3"]
b = [1,2,3]



15. Implement greatest of three numbers a=10,b=20,c=30 using ternary operator or regular if-else

a = int(input())
b = int(input())
c = int(input())
if a>b and a>c:
	print('a is greatest\n')
elif b>c:
	print('b is greatest\n')
else:
	print('c is greatest\n')

16.  Find int, bin, oct, hex of a number = 16

17. What is the difference between .py and .pyc file?

18. What is the difference between append and extend method?

19. Is the memory de-allocated once you exit Python console? How garbage collector works?

20. How is memory managed in Python?

21. Read capital letters and punctuations from a sentence.

22. join() and split() What is the difference
explain with a sentence example.

23. What does pass statement do in Python?

24. Write a program to check if a given year is leap year of not.

25. Write a program to check if the given pair of numbers form a right angled triangle.
(Hint: check a2 + b2 = c2)

26. Write a python program to count the number of bits set in an integer
e.g., a = 20 (bits: 0001 0100) answer 2 bits set.s

27. Write a program to check if the given number is a power of 2

28. Write a program to find the highest number in the given loop.
e.g., l1 = [10,33,45,56,78,98] output should be 98

print(max(l1))



29. Write a program to perform matrix multiplication
a = [[1,2,3],[4,5,6]] b = [[1,2,3],[4,5,6],[7,8,9]]



30. Write a program to reverse the bits in an integer
e.g., a = 0x12 (0001 0010) output = (1110 1101)
