- Using Python: The function takes a string (ex: '..^<>..vv'), an integer n, width, height, and depth as inputs. Returns the n'th part of the string. I am very confused on how to incoporate the depth into this problem (i.e. making it 3D instead of 2D).I need help to write a function that: 1. Take two parameters, a nucleotide sequence as a string, and an integer. 2. Check for invalid characters (not ATCG). If invalid character is found, exit function 3. Make the entire string lower case 4. For X iterations, where x is the integer parameter - Choose a character position in the string at random - Determine which nucleotide is at that position. At random, select a different nucleotide and replace the previous nucleotide with the new one. Use String splicing, or list() and "".join() -The new nucleotide should be uppercase so that the substitution is clear and obvious. 5. Test your code to make sure this behavior works as intended. Keep the number of iterations low, and add in a reporting mechanism that makes it clear what is happening (what position was chosen, what new nucleotide was chosen, etc). Comment out this out once you're sure the function works as it should. 6. Return the new string Python ProgrammingThe input/output table below defines a function f(x, y, z).

- Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When…I need help with this python computer science DEEP BREADTH SEARCH question. I have the layout of the code but I need help filling in the parts that say "pass" and I want you to take a picture of your output and make sure it matches the sample run below. Find a path (not the best path, but just any path) from A to Z. You see that the green path is not the shortest but it does let us navigate from start to finish. (The picture below) First, we need to know A and Z, our starting and ending points. We'll pass these into our function. I'm going to use a dictionary to represent this graph. Each node (vertex, circle) will have a name, in this case "A" and "Z" were the names of the nodes, but in the generated maps I'm going to use "Node 1", "Node 2", "Node 3", etc. Here is an example web_map web_map = { 'Node 1': ['Node 3', 'Node 2'], 'Node 2': ['Node 1', 'Node 4'], 'Node 3': ['Node 1'], 'Node 4': ['Node 2'] } Node 1 is connected to 2 and 3 for instance, and then also note that…python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments. How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...')

- What exactly are these things called "local area networks" (LANs)?Please do not give solution in image format thanku Write a python program that does the following. Make sure it works and can interface with the user in PyCharm. Write a function word count that will take a sentence (string) and return to you the number of words in the sentence. Show it works by calling it with “Cinderella must get to the ball without her slippers.” (Answer should be 9)Using import sys : Create a python program, palindrome.py, that has a function that takes one stringargument and prints a sentence indicating if the text is a palindrome. Thefunction should consider only the alphanumeric characters in the string, and notdepend on capitalization, punctuation, or whitespace.If your string is a palindrome it should print:It's a palindrome!If it is not a palindrome, it should print:It's not a palindrome!
- Exercise 5 The greatest common divisor (GCD) of a and b is the largest number that divides both of them with no remainder. One way to find the GCD of two numbers is based on the observation that if r is the remainder when a is divided by b, then gcd(a, b) = gcd(b, r). As a base case, we can use gcd(a, 0) = a. Write a function called gcd that takes parameters a and b and returns their greatest common divisor.Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003 main.cpp #include <iostream>#include <string> using namespace std; int DateParser(string month) {int monthInt = 0;if (month == "January")monthInt = 1;else if (month == "February")monthInt = 2;else if (month == "March")monthInt = 3;else if (month == "April")monthInt = 4;else if (month == "May")monthInt = 5;else if (month == "June")monthInt = 6;else if (month == "July")monthInt = 7;else if (month == "August")monthInt = 8;else if (month == "September")monthInt = 9;else if (month == "October")monthInt = 10;else if (month ==…Rewrite Listing 2.9, ComputeDistance.py, using the following function for computing the distance between two points.def distance(x1, y1, x2, y2):
