Let's assume a task which has been given your boss or teacher or staff's. (i.e) Get domain name of the email address of the students in the class or the employee's in the office. Tips :  Get all characters next to @ symbol . Source Code: import re variable=re.findall(r"@\w+", "dharani@gmail.com,  dharan@googlebird.in,  mymail@bird.com, dd@facebook.com")  print variable Output: F:\Knowledge\Python\LearningProgramsOwn>Domain.py ['@gmail', '@googlebird', '@bird', '@facebook'] Explanation : import regular expression. re.findall(r"@\w+", "values@domain.com")  - This line is used to extract the values from the mail address and store in on the variable. Which is an Regex Operation which we learn Previously .  Print the variable. To know  What is Python Regex ? what are the application of Regex? Thanks and regards, Tech Bird ...

For eg: calling match() on the string "Google Bird" and looking for "Google" will match. In case if your are going to look for Bird it will not match because match() will only recognize only the starting position of the string.

Prime number are those when a number is divided by same number or then by 1 it should give you the remainder as Zero. Eg: 2, 3, 5, 7, 11, 13, 17, 19 Note Worthy: 0 and 1 are not prime numbers. The 2 is the only even prime number because all the other even numbers can be divided by 2. Source Code: number  =  int(input("Enter the number to check prime or not:")) if number > 1:    for i in range(2, number):       if (number % i) == 0:            print number, "is not a prime number"       ...
