Perfect number, is defined as a positive integer which is equal to the sum of all its proper divisors. For example ,the smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect include numbers are 28, 496, and 8,128. Write a function perfect_number(n1,n2), which find perfect number between the given input of n1 and n2 and returns them in an array . Note: the input numbers n1 and n2 are to be included in the interval, while searching for the perfect numbers The input arguments: - n1: an integer variable ,giving us the start of the range of the interval - n2: an integer variable ,giving us the end of the range of the interval The output arguments: - output:An array that holds all the perfect numbers in the given interval for example: n1=1; n2=30; We then pass this to the function output = perfect_number(n1, n2) This results in the output: output=6,28

The function doit(a,b,c,d) is a function that multiplies the smallest of its integers arguments by 2. If more than one arguments are equal and are the smallest, they are multiplied by 2. For example given a=5,b=3,c=7,d=9, doit (a,b,c,d) changes b to 6. Write the code of the function doit and test it.
A pandigital number contains all digits (0-9) at least once. Write a function that takes an integer, returning true if the integer is pandigital, and false otherwise. Examples isPandigital (98140723568910) true isPandigital (90864523148909) → false // 7 is missing. isPandigital (112233445566778899) → false
The numpy module contains functions to generate random permutations. Given a non-negative integer n, every permutation of 2n numbers can be turned into a matching by taking the first half of the permutation entries (i.e., the first n numbers) and connecting each of them to the corresponding entry in the second half (i.e., the last n numbers). Use this method to write a function random_matching that takes n and returns a randomly selected matching of 2n numbers in the form of a list of n tuples, where each tuple contains two integers. Note: Ensure that the tuples are returned such that the first integer is less than the second integer. To demonstrate that your code works, draw the arc diagrams for five randomly chosen matchings of 20 numbers.
A natural number is prime if it is greater than 1 and has no divisors other than 1 and itself. Example: 8 isn't a prime number, as you can divide it by 2 and 4 (we can't use divisors equal to 1 and 8 as the definition prohibits this). On the other hand, 7 is a prime number as we can't find any legal divisors for it. Your task is to write a function checking whether a number is prime or not. in phython langauge Ques: The function: is called IsPrime() takes one argument (the value to check) returns True if the argument is a prime number, and False otherwise. Hint: try to divide the argument by all subsequent values (starting from 2) and check the remainder - if it's zero, your number cannot be a prime; think carefully about when you should stop the process. If you need to know the square root of any value you can utilize the ** operator. Remember: the square root of x is the same as x**0.5 Write a code that calculates all the prime numbers between 1 and 20. (Hint: Use a loop and…

REVERSED SUM OF ODD POSITIONS Write a function that takes an integer(n) as input and returns True if the sum of its digits at odd positions is even, and returns False of otherwise. Positions are counted from the least significant digit. stion For example: n = 2345 →> True Explanation: The digits at odd positions are 5 and 3, and their sum i.e. 8 is even. Examples: rev_sum of odd_pos(2345) - True - False rev_sum_of_odd_pos(5728) *Note: Please return your output. Don't print your answer inside the function. Your code will not get evaluated, if you are using 'print statement inside the function." Answer: (penalty regime: 0 %) Reset answer 1-def rev_sun of odd pos (n: int)-> bool: 2 merite your code from here e
Complete the count_consonants () function that takes a single string parameter - text. This function counts and returns the number of consonants in the text. A consonant is an alphabetical character that is not a vowel (i.e., an alphabetical character that is not an "a", "e", "i", "o" or "u"). The function must be able to count consonants regardless of case. Some examples of the function being called are shown below. Note: • You may find the isalpha () and lower () string methods useful for this exercise. • Please only provide the function definition. For example: Test text"Hello World" print("Number of consonants ", count_consonants (text)) text "A quick brown fox" print("Number of consonants", count_consonants (text)) Result Number of consonants = 7 Number of consonants - 9
Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50 code: # TODO: Import math module def quadratic_formula(a, b, c):# TODO: Compute the quadratic formula results in variables x1 and x2return (x1, x2) def print_number(number, prefix_str):if float(int(number)) == number:print("{}{:.0f}".format(prefix_str, number))else:print("{}{:.2f}".format(prefix_str, number)) if __name__ == "__main__":input_line = input()split_line = input_line.split(" ")a =…
Write a DECIMATOR function that takes a unit of character and minimizes it (i.e. removes the last 1/10 of characters). Always zoom in: if a bullet unit has 21 characters, 1/10 of the characters will be 2.1 characters, so DECIMATOR removes 3 characters. DECIMATOR is not kind! Examples decimator ("1234567890") 12 "123456789" # 10 characters, taken out 1. decimator ("1234567890AB") # 12 characters, 2 are released. "1234567890" decimator ("123") "12" # 3 characters, taken out 1. decimator ("123456789012345678901") # 21 characters, issued 3. Solve in Ruby "123456789012345678"
The least common multiple (lcm) of two positive integers u and v is the smallest positive integer that is evenly divisible by both u and v. Thus, the lcm of 15 and 10, written lcm(15, 10), is 30 because 30 is the smallest integer divisible by both 15 and 10. Write a function lcm() that takes two integer arguments and returns their lcm . The lcm() function should calculate the least common multiple by calling the gcd() function from program 7.6 in accordance with the following identity
