1) WAP IN PYTHON TO CHECK WHETHER THE STRING IS SYMMETRICAL OR PALINDROME.
===========================================================================

# WAP IN PYTHON TO CHECK WHETHER THE STRING IS SYMMETRICAL OR PALINDROME

# creating two functions
# function1 ==> to check palindrome
# function2 ==> to check the string symmetrical

    rev = s[::-1]
    return rev == s

def isSymmetrical(s):
    length = len(s)
    center = length // 2    # the center of the string

    if length % 2 == 0:
        return s[:center] == s[center:]
    else:
        return s[:center] == s[center+1:]

string = input("Enter a string:")

    print("The Given String is Symmetrical.")
else:
    print("The Given string is not Symmetrical")

if isPalindrome(string):
    print("The Given String is Palindrome")
else:
    print("The Given string is Not palindrome")

===========================================================================
# WAP TO REVERSE THE STRING WITHOUT SLICING

string = input("Enter a string:")
rev = ""

for i in string:
    rev = i + rev # rev + i

print("The String after the reverse = ",rev)
=================================================================
# WAP IN PYTHON TO REVERSE WORDS IN A GIVEN STRING
# HINT:
# S = "OBJECT ORIENTED PROGRAMMING LANGUAGE"
# OP = "LANGUAGE PROGRAMMING ORIENTED OBJECT"

string = input("Enter a string:")

# string into list
# reverse the list words
# we need join that list into string

# ld = string.split()
#
# print(string)
# print(ld)
#
# rev_ld = ld[::-1]
# print(rev_ld)
#
# res_string = ' '.join(rev_ld)
#
# print(res_string)

res_list = string.split()[::-1]

res_string = ' '.join(res_list)

print(res_string)

============================================

# WAP IN PYTHON TO FIND THE MAXIMUM OF LIST.

# max() ==> return the maximum from group of numbers
# min() ==> return the minimum from group of numbers

ld = eval(input("Enter a list:"))

# print("The Maximum of the list = ",max(ld))
# print("The Minimum of the list = ",min(ld))

ld.sort() # sorting in ascending order

===================================================
# WAP IN PYTHON TO INTERCHANGE FIRST AND LAST ELEMENTS IN A LIST

myList = eval(input("Enter a list:"))

    #
    # dummy = myList[0]
    # myList[0] = myList[length - 1]

    # list packing
    dummy = myList[-1],myList[0] # [1024, 121]

    # Unpacking the list
    myList[0],myList[-1] = dummy # [0] = 1024 [-1] = 121
    
    return myList
