Define a Python function named count_primes that consumes two int arguments start and stop and returns the number of prime integers between start (inclusive) and stop (exclusive). You may assume that start will be less than stop and that they are both ints. You may use the pre-defined function named is_prime which consumes a positive number and returns True if the number is prime and False if the number is not prime. For example: Test Result print(count_primes(10,20)) 4

Define a Python function named count_primes that consumes two int arguments start and stop and returns the number of prime integers between start (inclusive) and stop (exclusive).
You may assume that start will be less than stop and that they are both ints.
You may use the pre-defined function named is_prime which consumes a positive number and returns True if the number is prime and False if the number is not prime.
For example:

- In this challenge, the task is to debug the existing code to successfully execute all provided test files. Python supports a useful concept of default argument values. For each keyword argument of a function, we can assign a default value which is going to be used as the value of said argument if the function is called without it. For example, consider the following increment function: defincrement_by(n,increment=1):returnn+increment The functions works like this: >>>increment_by(5,2)7>>>increment_by(4)5>>> Debug the given function print_from_stream using the default value of one of its arguments. The function has the following signature: defprint_from_stream(n,stream) This function should print the first values returned by get_next() method of stream object provided as an argument. Each of these values should be printed in a separate line. Whenever the function is called without the stream argument, it should use an instance of EvenStream class defined in…Please answer it in Python Write a double_consonant function , It takes a word as a parameter and has two return values : A Boolean value equals True If the word contains a double consonant ( The same consonant twice in a row ), under these circumstances , The second value returned is the double consonant ; If there are no double consonants , Function should return False and None. relevant information : To simplify the exercise , We don't use words that contain multiple double consonants ( for example ,“successor”) Test your functionality on .

- Please answer it in Python Write a function input_names that takes as an argument a number player (supposedly valid) corresponding to the number of players who will play the game and which successively asks for the name of each player. The function verifies that the names of the players are all different and returns the list of the names of the players. The messages will ‑have to be clear. For example: input_names(3) #return => Enter player name 1: rara Enter player name 2: rara Enter player name 2: riri Enter player name 3: roro [“rara”,”riri”,”roro”] Input_names(2) #return => Enter player name 1: roro Enter player name 2 : raraWrite a function (define) the_divisor(n, bound), that takes in two int values. N is the number you search for a divisor and bound will also be an integer. The function the_divisor should return the smallest divisor which is greater than bound. If no such integers exists, return -1. You cannot assume that the first argument will be larger than the second.

- Please answer it in Python Write a function double_consonnant that takes as an argument a word and has two return values: a Boolean worth True if the word contains a double consonant (twice the same consonant in a row), and in this case the second return value is the consonant that is doubled; if there is no doubled consonant, the function must return False and None. If the word contains several double consonants (for example, 'successor'), true will be returned and the first double consonant appearing in the word. Examples: double_consonne('arrivee') is true, 'r'. double_consonne (‘bonbon’) is false, None double_consonne('appelle') is True, 'p'Write a python program that contains main and another custom function that generates a specified number of random integers in a specified range. The main function should prompt the user to enter three values for the desired number of random integers, the minimum value for the integers, and the maximum value for the integers. These three inputs should be passed as arguments to the custom function in main. The custom function should print the specified number of random integers in the specified range, all on one line separated by spaces as shown in the Sample Output below. The custom function should also determine and return the total of the random integers to main where it should be printed.Write a Python program that can convert Celsius to Fahrenheit ( or vice versa.) use two custom functions, f_to_c and c_to_f, to perform the conversions. Both of these functions should be defined in a custom module named 'temps'. Custom function c_to_f should be a void function defined to take a Celsius temperature as a parameter. It should calculate and print the equivalent Fahrenheit temperature accurate to one Custom function f_to_c should be a value-returning function defined to take a Fahrenheit temperature as a parameter. This function should calculate the equivalent Celsius temperature and return it. In the main function, your program should: **•prompt the user to enter a temperature (AS AN INTERGER).!!! •indicate the temperature scale of the temperature just entered. •call the appropriate function from the temps module. •USE F-STRING to display the equivalent temperature accurate to one decimal place.
- How can I write a python program that contains a main function and a custom, void function named show_larger that takes two random integers as parameters. This function should display which integer is larger and by how much. The difference must be expressed as a positive number if the random integers differ. If the random integers are the same, show_larger should handle that, too. In the main function, generate two random integers both in the range from 1 to 5 inclusive, and call show_larger with the integers as arguments.Create a python program called code.py. Write a function named divisible() that takes two integer parameters num1 and num2. Your function must print a random integer number x in the range [low…high] (inclusive), where low is the minimum of num1 and num2, and high is the maximum of num1 and num2. Next, if x is even or if x is divisible by 3, your function must return the squared value of x. otherwise, it should return 0. To test your function, ask the user for an integer number value (input validation is not necessary here), use a loop value times to call divisible() function and print the information returned by this function. You can use any two integers (for num1 and num2) of your choice to call the function. Note, you will not use the built-in min()/max() functions. Hint: to select a random integer, use the following. import random and call random.randint(low, high) that returns an int from the given range.write a function sequence in Python that accepts an number ( int ) and that prints a sequence of numbers that starts at the given number and obeys the following rules:the number 1 is the last number in the sequence (e.g stop )if the number if even, the next number is half of itif the number is odd, the next number is one moreSpecifications:use a while loopprint each number in the sequence one per line example usage: >>> sequence(3)3421
