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

Regex - Regular Expression Regular Expression are a special purpose text string operation used in programming language for search pattern. Primarily used for String searching and manipulation. For eg: If you need to find a certain word from a word document or log file this method might be handy for the programmers. Note Worthy: In Python, Regular Expression is denoted by Re and its is imported from the module re module. Methods that can used in Regular Expressions: re.split() re.match() re.search() re.findall() Simple Example of Regex in Python Syntax of split function: re.split('items to find and split', 'String in which operation to be performed') Eg:       re.split('\s', 'Hello world') item

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"            break    else:       print number, "is a prime number" else:      print number, "is not a prime number" Output:    Test case 1:       Enter a number : 10       10 is not a prime number Test case 2:       Enter a  number : 9

Getting the number to be reversed from the user by using input().   2. Initializing a variable rev=0.   3. Checking whether the given number is greater than Zero.
