S.No	File Name	Skill	Description	Hint	Difficulty
1	1.py	Print function	Write a Python HelloWorld code (Sanity check).	Hello World!
2	2.py	Version print	Write a Python program to get the Python version you are using.	Print the version using sys module	Easy
3	3.py	String format	Write a Python program to print a string in a specific format.	Edited string using \n and \t	Easy
4	4.py	Date time	Write a Python program to display the current date and time.	Date and Time	Easy
5	5.py	User stdin and math module	Write a Python program which accepts the radius of a circle from the user and compute the area.	Use input() and math.pi	Easy
6	6.py	String concatination	Write a Python program which accepts the user's first and last name and print them in reverse order with a space between them.		Easy
7	7.py	% modulo to find remainder and conditions	Write a Python program to print "YES" if the user input number is even, else print "NO"	n%2==0 for even number	Easy
8	8.py	Functions	Write a Python program to convert the given string into a morse code.	Morse code from internet	Easy
9	9.py	Array	Given a list of numbers and a number k, return whether any two numbers from the list add up to k.	Values should be < or = k	Easy
10	10.py	Array	Given an array of integers, return a new array such that each element at index i of the new array is the product of all the numbers in the original array except the one at i.		Easy
11	11.py	Array	Given an array of time intervals (start, end) for classroom lectures (possibly overlapping), find the minimum number of rooms required.		Easy
12	12.py	Stack	Given a string of round, curly, and square open and closing brackets, return whether the brackets are balanced (well-formed).	Use stack	Easy
13	13.py	String	You are given the firstname and lastname of a person on two different lines. Your task is to read them and print the following:Hello firstname lastname! You just delved into python.	String concatination	Easy
14	14.py	Functions and array	A fixed point in an array is an element whose value is equal to its index. Given a sorted array of distinct elements, return a fixed point, if one exists. Otherwise, return False.	Iteration	Easy
15	15.py	Dictionary	A classroom consists of N students, whose friendships can be represented in an adjacency list.Each student can be placed in a friend group, which can be defined as the transitive closure of that student's friendship relations. In other words, this is the smallest set such that no student in the group has any friends outside this group.	List merge	Easy
16	16.py	Stack	On a mysterious island there are creatures known as Quxes which come in three colors: red, green, and blue. One power of the Qux is that if two of them are standing next to each other, they can transform into a single creature of the third color.Given N Quxes standing in a line, determine the smallest number of them remaining after any possible sequence of such transformations.	Use stack.pop()	Easy
17	17.py	Array	A girl is walking along an apple orchard with a bag in each hand. She likes to pick apples from each tree as she goes along, but is meticulous about not putting different kinds of apples in the same bag.Given an input describing the types of apples she will pass on her path, in order, determine the length of the longest portion of her path that consists of just two types of apple trees.		Easy
18	18.py	Sorting and lambda	Given the names and grades for each student in a class of N students, store them in a nested list and print the name(s) of any student(s) having the second lowest grade.	Use key = lambda for sorting.	Easy
19	19.py	Conditions	Write a Python program for a rock-paper-scissors game.	Assign values like ROCK = 0; PAPER = 1; SCISSORS = -1.	Easy
20	20.py	Anagrams string	Given two words consisting of english letters (uppercase and lowercase) determine whether they are anagrams.	Use sort()	Easy
21	21.py	Next Bigger using str()	Create a function that takes a positive integer and returns the next bigger number that can be formed by rearranging its digits.		Easy
22	22.py	Least Larger	Given an array of numbers and an index, return the index of the least number larger than the element at the given index, or -1 if there is no such index ( or, where applicable, Nothing or a similarly empty value ).		Easy
23	23.py	Basic Sequence Practice	Complete the function that takes an integer n and returns a list/array of length abs(n) + 1 of the arithmetic series explained above. Whenn < 0 return the sequence with negative terms.		Easy
24	24.py	Reverser	Impliment the reverse function, which takes in input n and reverses it. For instance, reverse(123) should return 321. You should do this without converting the inputted number into a string.		Easy
25	25.py	Simple string expansion	Given a string, return the expansion of that string.		Easy
26	26.py	Ordered Weights	"56 65 74 100 99 68 86 180 90" ordered by numbers weights becomes: "100 180 90 56 65 74 68 86 99".		Easy
27	27.py	% and //	A number m of the form 10x + y is divisible by 7 if and only if x − 2y is divisible by 7. In other words, subtract twice the last digit from the number formed by the remaining digits. Continue to do this until a number known to be divisible or not by 7 is obtained; you can stop when this number has at most 2 digits because you are supposed to know if a number of at most 2 digits is divisible by 7 or not.
