When it is required to merge two lists and sort them, a method can be defined that sorts the list using ‘sort’ method.Below is the demonstration of the same −Example Live Demodef merge_list(list_1, list_2): merged_list = list_1 + list_2 merged_list.sort() return(merged_list) list_1 = [20, 18, 9, 51, 48, 31] list_2 = [28, 33, 3, 22, 15, 20] print("The first list is :") print(list_1) print("The second list is :") print(list_2) print(merge_list(list_1, list_2))OutputThe first list is : [20, 18, 9, 51, 48, 31] The second list is : [28, 33, 3, 22, 15, 20] [3, 9, 15, 18, 20, ...

Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. When it is required to check if two numbers are amicable numbers, a method can be defined that iterates over the number, and uses the modulus operator. Another method is defined that calls the previously defined function to determine if two numbers are amicable or not.Below is the demonstration of the same −Example Live Demoimport math def divided_sum_val(my_val) : res = 0 for i in range(2, int(math.sqrt(my_val)) + 1) : ...

When it is required to compute a polynomial equation when the coefficients of the polynomial are stored in a list, a simple ‘for’ loop can be used.Below is the demonstration of the same −Example Live Demomy_polynomial = [2, 5, 3, 0] num = 2 poly_len = len(my_polynomial) my_result = 0 for i in range(poly_len): my_sum = my_polynomial[i] for j in range(poly_len - i - 1): my_sum = my_sum * num my_result = my_result + my_sum print("The polynomial equation for the given list of co-efficients is :") print(my_result)OutputThe polynomial equation for the given list of co-efficients ...

Strong number is a number whose sum of all digits’ factorial is equal to the number ‘n’. Factorial implies when we find the product of all the numbers below that number including that number and is denoted by ! (Exclamation sign), For example: 5! = 5x4x3x2x1 = 120. When it is required to check if a number is a strong number or not, the remainder/modulus operator and the ‘while’ loop can be used.Below is the demonstration of the same −Example Live Demomy_sum=0 my_num = 296 print("The number is") print(my_num) temp = my_num while(my_num): i=1 fact=1 remainder = my_num%10 ...

A number is said to be a Perfect Number when that is equal to the sum of all its positive divisors except itself. When it is required to check if a number is a perfect number, a simple ‘for’ loop can be used.Below is the demonstration of the same −Example Live Demon = 6 my_sum = 0 for i in range(1, n): if(n % i == 0): my_sum = my_sum + i if (my_sum == n): print("The number is a perfect number") else: print("The number is not a perfect number")OutputThe number is a perfect numberExplanationThe ...

When it is required to convert gray code to binary code, a method is defined, that checks to see if the number is 0 or not.Below is the demonstration of the same −Example Live Demodef flip_num(my_nu): return '1' if(my_nu == '0') else '0'; def gray_to_binary(gray): binary_code = "" binary_code += gray[0] for i in range(1, len(gray)): if (gray[i] == '0'): binary_code += binary_code[i - 1] else: binary_code += flip_num(binary_code[i - 1]) return binary_code gray_code = "01101001" print("The gray code ...

When it is required to generate gray codes with the help of recursion, a method is defined, that creates an empty list and appends values 0 and 1 to it. Multiple ‘for’ loops are used to generate the gray code within the function.Below is the demonstration of the same −Example Live Demoimport math as mt def generate_gray_list(my_val): if (my_val = 1
