Python Most Used Coding ..SCR's Part _I

 #Define the Function For palindrome

#.palindrome Means Original String =Reverse String 

def is_palindrome(string):

    reversed_string = string[::-1]

    return string == reversed_string

# Test the function

word = input("Enter a word: ")

if is_palindrome(word):

    print(f"{word} is a palindrome")

else:

    print(f"{word} is not a palindrome")

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

# Factorial  2 is Formula n! = n × (n-1)! 2!=2*1

# n!=n×(n−1)×(n−2)×⋯×2×1

#Ex:1*2 =2 then 2*3=6 then 6*4=24 then 24*5=120 then 120*6 #Like that it will work

def factorial(n):

    if n == 0:

        return 1

    else:

        return n * factorial(n-1)

# Test the function

number = int(input("Enter a number: "))

result = factorial(number)

print(f"The factorial of {number} is {result}")

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

#Find the largest Number in List

#========== Using Sort  Method=======

numbers = [10, 25, 5, 40, 15]

numbers.sort(reverse=False) # OP:[5, 10, 15, 25, 40]

print(f"Largest Number in List Is  :: {numbers[-1]}") #OP :40

##Find the Second-Largest Number in List

print(f"Second Largest Number in List Is  :: {numbers[-2]}")

# Using Max Function

numbers1 = [10, 25, 5, 40, 15]

numbers1=max(numbers1)

print(f"Largest Number in List Is Using Max  :: {numbers1}")

# Using Loops

numbers2 = [10, 25, 5, 40, 15]

largest = numbers2[0] # Means Its Take 10 Value From List

for num in numbers2: # looping list 

    if num > largest:  # Checking List elements 

        largest = num # Find the Element 

print("Largest element:", largest)

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

With Out using Sort Function Sort the String

numbers = [10, 25, 5, 40, 15]

n = len(numbers)

for i in range(n):

    for j in range(0, n-i-1):

        if numbers[j] > numbers[j+1]:

            # Swap

            numbers[j], numbers[j+1] = numbers[j+1], numbers[j]

print("Sorted list:", numbers)

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

#Using Python slicing Method
Text= "PYTHON"
S1= Text[::-1]
print(f"Reverse of Word Of {Text}  Is   {S1}")
#Using Reverse Function
text1="MADAm"
reverse_text="".join(reversed(text1))
print(f"Reverse of Word Of {text1}  Is   {reverse_text}")
#Using Loop
text2 =input("Enter a String")#===>Hello
reversed_text = ""
for char in text2:
    reversed_text = char + reversed_text
print("Reversed string:", reversed_text)

==OP===========
Reverse of Word Of PYTHON  Is   NOHTYP
Reverse of Word Of MADAm  Is   mADAM
Enter a StringHello
Reversed string: olleH
