This repository is created to store my solutions for the Python interview questions for a web developer position at RAINMAKER LABS.

Question 1 - You are given an HTML form, which contains the following entries: ... The above form has been submitted using the "POST" method. Write code that will determine which checkboxes have been checked and print, in a space separated list, the checkbox numbers that were checked. For example, if check-boxes 3, 5, and 10 are checked, you would print 3 5 10

Answer 1 - I assumed that the framwork being used in the web project was Flask. I created a simple Flask backend just to process the data in the POST request and print the checkbox numbers. My very simple barebone HTML template file (Question 1/app/templates/form_submit.html) attempts to re-create the scenario in the question by creating a form that has 10 checkboxes and one 'Submit' button. My backend logic file (Question 1/app/views.py) contains the required code to parse the POST request and print the checkbox numbers.

Question 2 - You are given an array in Python, which contains positive integers and/or recursively nested arrays of positive integers. It may, for example, be initialized as: arr = [[141,151,161],2,3,[101,202,[303,404]]] Write a function def MaxArray(arr) which returns the maximum value contained in arr or some array nested within arr. In the example, the returned value should be 404.

Question 3 - Write a function declared as def SplitEmailAddress(address), whose argument will contain string data consisting of a valid e-mail address. This function will take the email address as the argument and return a dictionary with two keys: user for the username part and domain for the domain part of the address. For example, after calling: dict = SplitEmailAddress('myuser_1@mailserver.example.com') dict['user'] should contain the string myuser_1, and dict['domain'] should contain the string mailserver.example.com

Question 4 - Write a function GetLongestString, whose arguments are character strings. It should return an integer representing the length of the longest string passed as its argument; for example: GetLongestString("a", "aaa", "aa") should return 3, GetLongestString("a", "bcd", "efgh", "ij", "") should return 4.

Question 5 - Write a function GetUniqueOnes, which accepts a single argument. The argument is an array of integers, and the function should return the unique integers separated by commas. For Example : GetUniqueOnes(arr) arr = [34,54,67,68,141,151,161,141,54,151,54] should return 34,54,67,68,141,151,161

Question 6 - Write a function ReadXml(xmlstr) which accepts an XML string as its only argument. Your function should write the names of the nodes and their values. For Example : ReadXml(xmlstr) where xmlstr= '

JamesJaniReminderPlease check your mail.' should return Address to: James from: Jani heading: Reminder body: Please check your mail. Note: As the question requires the output to be displayed in the new/ next line, use "\n" instead of "
"

Question 7 - Consider a database with one table called "user" having two fields: "id" (type: INTEGER, PRIMARY KEY) "name" (type: VARCHAR(32)) Write a standard SQL query which retrieves the second highest value of "id" from the "user" table. The value returned should be represented using the column name "id".

Question 8 - Write a function GeneratePassword which accepts two arguments, an integer and a character string consisting of letters (a-z) and digits (0-9). When GeneratePassword(5,'abc0123') is called, it should return a random string of 5 characters taken from 'abc0123'. For Example : GeneratePassword(7,'abczxc012394') could return any of the following outputs : 2c00acb 2c23z93 030b2a4

Question 9 - Write a program that outputs the numbers that are divisible by 8 and are between 200 and 600 (inclusive), separated by commas (without spaces or line breaks).

Question 10 - Write a function declared as function ReformatPhoneNumber(number), whose argument will contain string data representing some phone number data (entered by the user). A valid phone number may consist of between 7 and 12 digits (0..9). Assume that in between some adjacent digits there may optionally appear either a single space, or a single hyphen (-). Any other phone number should be considered invalid. If the phone number is valid, the return value of your function should contain a string containing between 7 and 12 digits, representing the same phone number after removing all hyphens and spaces. If the phone number is invalid, throw a custom Python Exception with the message "Invalid phone number". The first and the last character of the string should be a number. For example, after calling ReformatPhoneNumber('012-345 69') the return value should be '01234569'. Calling the function with any of these values: '012345', '-012345 678', '01203- 34566', '123456678875432', '1234x567' should result in an exception.
