When it is required to print all possible combination of digits when the input is taken from the user, nested loop is used.Below is a demonstration of the same −Example Live Demofirst_num = int(input("Enter the first number...")) second_num = int(input("Enter the second number...")) third_num = int(input("Enter the third number...")) my_list = [] print("The first number is ") print(first_num) print("The second number is ") print(second_num) print("The third number is ") print(third_num) my_list.append(first_num) my_list.append(second_num) my_list.append(third_num) for i in range(0, 3):    for j in range(0, 3):       for k in range(0, 3):          if(i!=j&j!=k&k!=i):     ...

When it is required to read two numbers and print the quotient and remainder when they are divided, the ‘//’ and ‘%’ operators can be used.Below is a demonstration of the same −Example Live Demofirst_num = int(input("Enter the first number...")) second_num = int(input("Enter the second number...")) print("The first number is ") print(first_num) print("The second number is ") print(second_num) quotient_val = first_num//second_num remainder_val = first_num%second_num print("The quotient is :") print(quotient_val) print("The remainder is :") print(remainder_val)OutputEnter the first number...44 Enter the second number...56 The first number is 44 The second number is 56 The quotient is : 0 The remainder is : ...

When it is required to print all the elements in a given range that is divisible by a specific number, a simple for loop can be used.Below is a demonstration of the same −Example Live Demolower_num = int(input("Enter lower range limit...")) upper_num = int(input("Enter upper range limit...")) div_num = int(input("Enter the number that should be divided by...")) for i in range(lower_num, upper_num+1):    if(i%div_num==0):       print(i)OutputEnter lower range limit...3 Enter upper range limit...8 Enter the number that should be divided by...2 4 6 8ExplanationThe upper and lower range of numbers is taken as input from the user.The number by ...

When it is required to take a number and compute a specific pattern, the value of n is taken from the user. Next, two variables are assigned this specific pattern and their sum is calculated.Below is a demonstration of the same −Example Live Demomy_input = int(input("Enter a value for n...")) temp_val = str(my_input) t_1=temp_val+temp_val t_2=temp_val+temp_val+temp_val my_result = my_input+int(t_1)+int(t_2) print("The computed value is : ") print(my_result)OutputEnter a value for n...4 The computed value is : 492ExplanationAn input from the user is taken.It is converted into a string and assigned to a variable.The value of ‘n*n’ and the value of ‘n*n*n’ is calculated.Their ...

When it is required to sort the elements of an array in descending order, the ‘sort’ method can be used by specifying a parameter named ‘reverse’ to True.Below is a demonstration of the same −Example Live Demomy_list = [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] print("The list is :") print(my_list) my_list.sort(reverse = True) print("The list after sorting is :") print(my_list)OutputThe list is : [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] The list after sorting is : [89, 78, 56, 44, 42, 31, 23, 11, 9, 0]ExplanationA list is defined, and is displayed on the console.The ...

When it is required to sort the elements of an array in ascending order, the ‘sort’ method can be used. It helps sort the elements in ascending order by default. If we want it to be sorted in descending order, a parameter named ‘reverse’ can be set to True.Below is a demonstration of the same −Example Live Demomy_list = [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] print("The list is :") print(my_list) my_list.sort() print("The list after sorting is :") print(my_list)OutputThe list is : [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] The list after sorting is : ...

When it is required to right rotate the elements of a list, the elements are iterated over, and a last element is assigned a value, after which the elements are iterated over, and an element is swapped.Below is a demonstration of the same −Example Live Demomy_list = [31, 42, 13, 34, 85, 0, 99, 1, 3] n = 3 print("The value of n has been initialized to") print(n) print("The list is :") print(my_list) print("List is being right rotated by 3 elements...") for i in range(0, n):    last_elem = my_list[len(my_list)-1]    for j in range(len(my_list)-1, -1, -1):     ...

When it is required to print the elements of a list that are present at even index/position, a loop can be used to iterate over the elements, and only check the even positions in the list by specifying the step size as 2 in the range function.Below is a demonstration of the same −Example Live Demomy_list = [31, 42, 13, 34, 85, 0, 99, 1, 3] print("The list is :") print(my_list) print("The elements in odd positions are : ") for i in range(0, len(my_list), 2):    print(my_list[i])OutputThe list is : [31, 42, 13, 34, 85, 0, 99, 1, 3] The elements ...

When it is required to print the elements of an array in reverse order, the list can be iterated over from the end.Below is a demonstration of the same −Example Live Demomy_list = [21, 32, 43, 54, 75] print("The list is : ") for i in range(0, len(my_list)):    print(my_list[i]) print("The list after reversal is : ") for i in range(len(my_list)-1, -1, -1):    print(my_list[i])OutputThe list is : 21 32 43 54 75 The list after reversal is : 75 54 43 32 21ExplanationA list is defined, and is displayed on the console.The list is iterated over, and displayed.It is reversed ...
