Introduction To Python

Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.

Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

Symmetric Difference in Python – HackerRank Solution

Today, we’re learning about a new data type: sets.


If the inputs are given on one line separated by a character (the delimiter), use split() to get the separate values in the form of a list. The delimiter is space (ascii 32) by default. To specify that comma is the delimiter, use string.split(‘,’). For this challenge, and in general on HackerRank, space will be the delimiter.


>> a = raw_input()
5 4 3 2
>> lis = a.split()
>> print (lis)
['5', '4', '3', '2']

If the list values are all integer types, use the map() method to convert all the strings to integers.

>> newlis = list(map(int, lis))
>> print (newlis)
[5, 4, 3, 2]

Sets are an unordered collection of unique values. A single set contains values of any immutable data type.


>> myset = {1, 2} # Directly assigning values to a set
>> myset = set()  # Initializing a set
>> myset = set(['a', 'b']) # Creating a set from a list
>> myset
{'a', 'b'}


Using the add() function:

>> myset.add('c')
>> myset
{'a', 'c', 'b'}
>> myset.add('a') # As 'a' already exists in the set, nothing happens
>> myset.add((5, 4))
>> myset
{'a', 'c', 'b', (5, 4)}

Using the update() function:

>> myset.update([1, 2, 3, 4]) # update() only works for iterable objects
>> myset
{'a', 1, 'c', 'b', 4, 2, (5, 4), 3}
>> myset.update({1, 7, 8})
>> myset
{'a', 1, 'c', 'b', 4, 7, 8, 2, (5, 4), 3}
>> myset.update({1, 6}, [5, 13])
>> myset
{'a', 1, 'c', 'b', 4, 5, 6, 7, 8, 2, (5, 4), 13, 3}


Both the discard() and remove() functions take a single value as an argument and removes that value from the set. If that value is not present, discard() does nothing, but remove() will raise a KeyError exception.

>> myset.discard(10)
>> myset
{'a', 1, 'c', 'b', 4, 5, 7, 8, 2, 12, (5, 4), 13, 11, 3}
>> myset.remove(13)
>> myset
{'a', 1, 'c', 'b', 4, 5, 7, 8, 2, 12, (5, 4), 11, 3}

COMMON SET OPERATIONS Using union()intersection() and difference() functions.

>> a = {2, 4, 5, 9}
>> b = {2, 4, 11, 12}
>> a.union(b) # Values which exist in a or b
{2, 4, 5, 9, 11, 12}
>> a.intersection(b) # Values which exist in a and b
{2, 4}
>> a.difference(b) # Values which exist in a but not in b
{9, 5}

The union() and intersection() functions are symmetric methods:

>> a.union(b) == b.union(a)
>> a.intersection(b) == b.intersection(a)
>> a.difference(b) == b.difference(a)

These other built-in data structures in Python are also useful.

Given  sets of integers,  and , print their symmetric difference in ascending order. The term symmetric difference indicates those values that exist in either  or  but do not exist in both.

Input Format

The first line of input contains an integer, .
The second line contains  space-separated integers.
The third line contains an integer, .
The fourth line contains  space-separated integers.

Output Format

Output the symmetric difference integers in ascending order, one per line.

Sample Input

STDIN       Function
-----       --------
4           set a size M = 4
2 4 5 9     a = {2, 4, 5, 9}
4           set b size N = 4
2 4 11 12   b = {2, 4, 11, 12}

Sample Output

N = int(input())

  1. Does your website have a contact page? I’m having a tough time locating it but, I’d like to shoot you an e-mail. I’ve got some suggestions for your blog you might be interested in hearing. Either way, great blog and I look forward to seeing it develop over time.

  5. Hi there this is kinda of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get advice from someone with experience. Any help would be greatly appreciated!

  6. Wonderful blog! Do you have any hints for aspiring writers? I’m hoping to start my own website soon but I’m a little lost on everything. Would you suggest starting with a free platform like WordPress or go for a paid option? There are so many options out there that I’m completely confused .. Any recommendations? Thank you!

  7. Magnificent beat ! I would like to apprentice while you amend your site, how can i subscribe for a blog website? The account helped me a acceptable deal. I had been tiny bit acquainted of this your broadcast offered bright clear concept

  8. I really like your writing style, superb information, thank you for posting :D. “Nothing sets a person so much out of the devil’s reach as humility.” by Johathan Edwards.

  9. Combine your hand with the Dealer’s three-card hand to make your best five-card poker hand. You win with three of a kind or better (see pay table for odds). Betting games typically center around having the highest ranked hand in a group of players. Before the hands are dealt, betting games normally require an ante, or an initial bet that starts the pot, or the winner’s prize. After receiving their cards, players make bets over who has the highest ranked hand. Players do not need to bet according to their real hand; they can bluff, or lie, in hopes that other players fold from the game rather than challenge their hand. Either the last player betting or the player with the highest hand between the last players betting, wins the pot of bets. Download a quick how-to guide here. The game, also known as “3 Card Poker”, starts with a three-card deal for the player. In an additional level of excitement, players are also able to place parallel bets on either side of the main deal with each having a set of winning combinations.
    Besides an 840-room hotel, Sam’s Town has an RV park, which appeals to my current lifestyle. There are two floors of gambling fun to be had with the best selection of the iconic Buffalo Gold Revolution and Buffalo Legends I’ve seen yet.  In the heart of the action downtown, Caesars has several good restaurants and an inviting rooftop pool. That said, it’s not at the top of our list of Atlantic City casinos because of the environment. Between the super dark interior and stale cigarette smell, it’s not a place we want to hang out very long.
