#Q Sort a list of numbers in ascending and descending 

numbers = [45, 12, 78, 34, 89, 23]

# Sort in ascending order ascending = sorted(numbers)

# Sort in descending order descending = sorted(numbers, reverse=True) print("Original List:", numbers) print("Ascending Order:", ascending) print("Descending Order:", descending)

#Q :Remove a specific element from a list.

num = int(input("How many element enter : "))

element = []

for i in range(num):

    user_input =input("Enter your element: ")

    element.append(user_input)

print("Your element :", element)

rem_element = input("Enter your remove element no ")

element.remove(rem_element)

print(f"New List: {element}")

#output :

# How many element enter : 2

# Enter your element: a

# Enter your element: b

# Your element : ['a', 'b']

# Enter your remove element no b

# New List: ['a']

#Q : Insert an element at the second position in the list.

num = int(input("Enter your no : "))

number =[1,2,3,4,5]

number.insert(1,num)

#Q : Python program that prints the first and last elements of a list:

num = int(input("Enter your no i will print from start and last"))

    user_input=int(input(f"Enter your no : "))

    number.append(user_input)

print("First No :", number[0])

print("Last No :" , number[-1])

#Q:Ask the user to enter numbers and store them in a list.

print ("How many no you want to print: ")

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

numbers = []

for i in range(num):

    user_input = int(input(f"Enter the no {i + 1} : "))

#Q :create a new list that contains the squares of each number..

list =[2,3,4,5]

#Q: To add the number 100 to the beginning of a list in Python, you can use the .insert() method:

list = [1,10,100,100,1000]

list.insert(0,200)

print(list)

#Q :Create a list of 10 integers and print the first and last elements of the list.

for i in range(count):

    if i == 0 or i ==count-1:

        print(f"List no : {my_list[i]} ")

    choose = input("Do you want to continue y / n ")

    if choose.lower() !='y':

        break

       

 Q: Find the factorial of a number entered by the user.

while True:

        user_val = int(input("Enter the no: "))

        fact = 0

        sum =1

        for i in range(user_val):

               fact = user_val - i
