Python Program to Generate Gray Codes using Recursion
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 −Exampleimport math as mt def generate_gray_list(my_val): if (my_val = 1
Read MorePython Program to Convert Binary to Gray Code
When it is required to convert binary code to gray code, a method is defined that performs the ‘xor’ operation.Below is the demonstration of the same −Exampledef binary_to_gray_op(n): n = int(n, 2) n ^= (n >> 1) return bin(n)[2:] gray_val = input('Enter the binary number: ') binary_val = binary_to_gray_op(gray_val) print('Gray codeword is :', binary_val)OutputEnter the binary number: 101100110 Gray codeword is : 111010101ExplanationA method named ‘binary_to_gray_op’ is defined, that takes the binary number as its parameter.It performs the ‘xor’ operation.It returns the converted output.The input of binary number is taken from the user.The function is ...
Read MorePython Program to Check if a Number is a Perfect Number
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 −Examplen = 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 value ...
Read MorePython Program to Check if a Number is a Strong Number
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 −Examplemy_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 ...
Read MorePython Program to Compute a Polynomial Equation given that the Coefficients of the Polynomial are stored in a List
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 −Examplemy_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 is ...
Read MorePython Program to Check If Two Numbers are Amicable Numbers
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 −Exampleimport math def divided_sum_val(my_val) : res = 0 for i in range(2, int(math.sqrt(my_val)) + 1) : if ...
Read MorePython Program to Find the Gravitational Force Acting Between Two Objects
When it is required to find the gravitational force that acts between the two objects, a method named ‘find_gravity’ is used, and three parameters are passed to it.Below is the demonstration of the same −Exampledef find_gravity(m_1, m_2, r): G_val = 6.673*(10**-11) F_val = (G_val*m_1*m_2)/(r**2) return round(F_val, 2) m_1 = 6000000 m_2 = 1000000 r = 45 print("The gravitational force is: ") print(find_gravity(m_1, m_2, r), "N")OutputThe gravitational force is: 0.2 NExplanationA method named ‘find_gravity’ is defined, that takes three parameters.The gravitational force, and the gravitational constant are determined, and the force value is returned as output.Outside ...
Read MorePython Program to Merge Two Lists and Sort it
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 −Exampledef 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, 20, ...
Read MorePython Program to Find the Second Largest Number in a List Using Bubble Sort
When it is required to find the second largest number in a list using bubble sort, a method named ‘bubble_sort’ is defined, that sorts the elements of the list. Once this is done, another method named ‘get_second_largest’ is defined that returns the second element from the end as output.Below is the demonstration of the same −Examplemy_list = [] my_input = int(input("Enter the number of elements...")) for i in range(1, my_input+1): b=int(input("Enter the element...")) my_list.append(b) for i in range(0, len(my_list)): for j in range(0, len(my_list)-i-1): if(my_list[j]>my_list[j+1]): temp=my_list[j] ...
Read MorePython Program to Create a List of Tuples with the First Element as the Number and Second Element as the Square of the Number
When it is required to create a list of tuple, and have the first element as the number, and the second element as the square of the element, list comprehension can be used.Below is the demonstration of the same −Examplemy_list = [23, 42, 67, 89, 11, 32] print(“The list is “) print(my_list) print(“The resultant tuple is :”) my_result = [(val, pow(val, 2)) for val in my_list] print(my_result)OutputThe list is [23, 42, 67, 89, 11, 32] The resultant tuple is : [(23, 529), (42, 1764), (67, 4489), (89, 7921), (11, 121), (32, 1024)]ExplanationA list is defined, and is displayed on the ...
