### Task 3: Implement the `count_digits` Function**Objective:**Complete the function `count_digits`. This function takes one parameter - a string (`s`). It should return the number of digits in `s`. **Example:**If `s` is "25 or 6 to 4 is a song by Chicago", then `count_digits` should return `4`.**Instructions:**- The function `count_digits` should not print the result; it should return it.- Do not change anything outside the `count_digits` function.**Code Implementation:**```pythondef count_digits(s): '''Returns the number of digits in s''' pass # Hint: make a string of digits to use # in checking whether each character # is a digit. And use the accumulator # patternuser_string = input("Please enter a string: ")num_digits = count_digits(user_string)print("There are", num_digits, "digits in", user_string)```- **Line 1-2:** Define the function `count_digits` with parameter `s` and include a docstring.- **Line 3:** Use `pass` as a placeholder for future implementation.- **Lines 4-7:** Comments provide hints to implement the digit counting logic using a string of digits and an accumulator pattern.**User Interaction:**- **Line 9:** Prompt the user to enter a string.- **Line 10:** Call the `count_digits` function with the user input and store the result in `num_digits`.- **Line 11:** Print the number of digits found in the inputted string alongside the original string. ### ObjectiveComplete the function `show_upper`. This function takes one parameter - a string (`s`). It should return a string made up of all the upper-case characters in `s`. For example, if `s` is `"aBdDEfgHijK"`, then `show_upper` should return `"BDEHK"`. It should return the upper-case string - not print it. Do not change anything outside `show_upper`.### Code```pythondef show_upper(s): '''Returns the upper case characters from s''' passuser_string = input("Please enter a string: ")upper_chars = show_upper(user_string)print(upper_chars)```### Explanation1. **Function Definition**: - `show_upper(s)`: This function is designed to process the input string `s` and extract all the upper-case characters.2. **Docstring**: - Describes the purpose of the function to return upper-case characters from the input string `s`.3. **Main Program Flow**: - `user_string`: Prompts the user to input a string. - `upper_chars`: Calls the `show_upper` function, passing the `user_string` as an argument, and stores the result. - `print(upper_chars)`: Outputs the result to the console.### TaskImplement the logic inside `show_upper` to return the upper-case letters from the input string.

The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.

The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) { System.out.println(Recursion.countSubstring("catwoman loves cats","cat"));…

in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision. Assignment specifications Hold-at-20 means that the player will choose to roll…

Can this python code be done without using the isdigit() function. Please try to change the following code in the picture so it doesn't use isdigit().
Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
