Use regular expression to implement a function which accepts a passed string and check if it is a valid email address. A program accepts user's input and calls the email validation function. If the email is valid, print out the email, username and host. (Rule: word characters (a-zA-Z0-9_ or "w"), dot, and hyphen are considered as valid characters in an email address, besides of one & only one '@'.) (Sample output as shown in the following figure is for demonstration purposes only.)

The internet enables people to network, join a cause, take a poll, etc. Your program will prompt the user for a description of a poll to be taken and then prompt 5 users for a response of 1-10 (1 being a 'poor' response; 10 being the 'best' response).Your program does not have to validate that the user entered 1-10. We'll do that type of checking later.Your program must use a string data type to store the poll description and a Python list data type to save the integer responses of the 5 user responses.Your output should list all the responses stored in the list, the highest given response, the lowest given response and the average of the 5 responses. See sample input and utput below.Review powerpoint 3, slide 21 for an example if you need one.

Code is in C++ Instructions Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Input is as follows highlighted in bold John Doe 333224444 DoeJ 123Password My problem is with my output, i am close with the code, but i have attached what happens on my output and i cannot figure out why? You can see how it prints out multiple times but i am lost? The terminal image is also attached. Thank you!

Write a function that when given a URL as a string, parses out just the domain name and returns it as a string. Examples:domain_name("http://github.com/SaadBenn") == "github" domain_name("http://www.zombie-bites.com") == "zombie-bites"domain_name("https://www.cnet.com") == "cnet"Note: The idea is not to use any built-in libraries such as re (regular expression) or urlparse except .split() built-in function""" # Non pythonic waydef domain_name_1(url): #grab only the non http(s) part full_domain_name = url.split('//')[-1] #grab the actual one depending on the len of the list actual_domain = full_domain_name.split('.') # case when www is in the url if (len(actual_domain) > 2): return actual_domain[1] # case when www is not in the url return actual_domain[0] # pythonic one linerdef domain_name_2(url):
Write a function that accepts a string as an argument and returns true if the argument ends with the substring .doc'. Otherwise, the function should return false
Create a function that determines how many number pairs are embedded in a space-separated string. The first numeric value in the space-separated string represents the count of the numbers, thus, excluded in the pairings. Examples number_pairs("7 1 2 1 2 1 3 2") 2 // (1, 1), (2, 2) number_pairs ("9 10 20 20 10 10 30 50 10 20") 3 // (10, 10), (20, 20), (10, 10) number_pairs("4 2 3 4 1") → 0 // Although two 4's are present, the first one is discounted.

In Python Create a program that reads a full name as a single string, and and uses the split creates a username with the following rules: The first character of the username is the first character of the first name. The second character of the username is the first letter of the middle name, if one was provided. The rest of the characters will be a prefix of the last name, long enough to meet the length requirement. The username can have up to 8 characters only, and in lowercase.
