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.) In [24]: runfile('C:/tmp/units/2020/SIT384-2020-1/portfolio/week2/ Task2.3P.py', wdir='C:/tmp/units/2020/SIT384-2020-1/portfolio/week2') Please input your email address:test@ Not a valid email. Please input your email address: shang.gao@test2.server.com email: shang.gao@test2.server.com, username: shang.gao, host: test2.server.com

Suppose a String name is given in a format where the firstname and lastname are separated by a semicolon like ‘Ziaul;Hossain’ ; the general format would be ‘firstname;lastname’ (firstname and lastname can be any String). Write a program which will separate the lastname into a different string. (Hint: use a function from String class to find the position of semicolon and then take substring from that position).
The function derivate_leaf takes as argument an expression that is a leaf, and a variable, and returns the symbolic derivative of the leaf writh respect to the variable. (code should be in python). def derivate_leaf(e, x): """This function takes as input an expression e and a variable x, and returns the symbolic derivative of e wrt. x, as an expression.""" # YOUR CODE HERE should pass these test cases: assert derivate_leaf("x", "x") == 1 assert derivate_leaf("x", "y") == 0 assert derivate_leaf("y", "z") == 0 assert derivate_leaf(4, "x") == 0

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?

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.
