- Write a program that reads a list of names and total points for students until -1 is entered. After gettingall of names and points, it will output them as names and grades. Write your program using a functionthat gets the points as parameter and calculates the grade and return it. No input validation is required.Also write a function that unit test your grade calculator function.Bonus (5 points): validate your input in any way that you think works better for this situation.Show an error messageBring the points to a valid rangeReturn a value that shows an error has occurredA[94,100] A-[90,94) B+[87,90) B[84,87) B-[80,84) C+[77,80) C(74,77) C-[70,74) D+[67,70) D[61,67) F[0,61)Sample input:Lee 39Lua 86Mary 91Stu 72-1Sample output:Lee FLua BMary AStu C-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"Write a function that takes an integer. The function should return True if the integer is even and False otherwise. Use the function in a program that prompts for a number and prints "Even" or "Odd". Ex: If the input is: 15 the output is: Odd Ex: If the input is: 10 the output is: Even Your program must define and call the following function. The function should return a bool value (True or False).def is_even(num) python
- Write another version of the checkeven function. This version receives 3 integer variables and returns true if all three numbers are even. Otherwise, the function returns false. Write the statements to read in three numbers and call the checkeven function. Then print YES if all three numbers were even, or print NO if they were not all even.write another function drawLine(int x, int y) in the above code. this function should return length of lines by same method i.e., subtracting y from x.The ceiling of a floating-point number x is the smallest integer that is still larger than or equal to x. Alternatively, the ceiling of a floating-point number x is what you get when you round x up to the nearest integer. For example, the ceiling of 2.1 is 3, the ceiling of 0.9 is 1, the ceiling of -4.5 is -4, etc. Write a function called ceiling() to compute the ceiling of a float input parameter that returns one integer value. You may not use python’s ceil() or floor() functions. Your function may use int()/float() functions, and the floor division operator (i.e., '//').
- Write a function that takes a positive integer num and calculates how many dots exist in a pentagonal shape around the center dot on the Nth iteration. In the image below you can see the first iteration is only a single dot. On the second, there are 6 dots. On the third, there are 16 dots, and on the fourth there are 31 dots. Return the number of dots that exist in the whole pentagon on the Nth iteration. Examples pentagonal (1) → 1 pentagonal (2) <-6 pentagonal (3) - 16 pentagonal (8) → 141Re-write the following function so that a given XAND return the value of f(x).a. Write a function named countDigits that accepts a positive integer as its parameter and returns the number of digits in that number. For example, the number 8546587 has seven digits, so the call countDigits(8546587) should return 7. You may assume that the value passed to your method is non-negative. b. Write a program to input an integer n and call the above function in part a if n is positive, else give 'Value must be Positive' message. Inputting will stop when 0 is entered.
- Write a program in Python with a function perfectcube(n), which returns True if n is a perfect cube and returns False otherwise. Notice that this function is not printing anything, but rather returning True or False. The function must use exhaustive enumeration to check if n is a perfect cube. Use the function in a program where you ask the user for n and you print a statement like "Yes, that is a perfect cube" or "No, that number is not a perfect cube".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…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).
