[해커랭크(Hackerrank)/30 Days of Code/파이썬3(python3)] Day 0: Hello, World.

Objective 
In this challenge, we review some basic concepts that will get you started with this series. You will need to use the same (or similar) syntax to read input and write output in challenges throughout HackerRank. Check out the Tutorial tab for learning materials and an instructional video!

Task 
To complete this challenge, you must save a line of input from stdin to a variable, print Hello, World. on a single line, and finally print the value of your variable on a second line.

You've got this!

Note: The instructions are Java-based, but we support submissions in many popular languages. You can switch languages using the drop-down menu above your editor, and the  variable may be written differently depending on the best-practice conventions of your submission language.

Input Format

A single line of text denoting  (the variable whose contents must be printed).

Output Format

Print Hello, World. on the first line, and the contents of  on the second line.

Sample Input

Welcome to 30 Days of Code!

Sample Output

Hello, World. 
Welcome to 30 Days of Code!

Explanation

On the first line, we print the string literal Hello, World.. On the second line, we print the contents of the variable which, for this sample case, happens to be Welcome to 30 Days of Code!. If you do not print the variable's contents to stdout, you will not pass the hidden test case.

풀이

# Read a full line of input from stdin and save it to our dynamically typed variable, input_string.
input_string = input()

# Print a string literal saying "Hello, World." to stdout.
print('Hello, World.')
print(input_string)

# TODO: Write a line of code here that prints the contents of input_string to stdout.

설명

사실 해커랭크에서 이 파트는 알고리즘 풀이에 분류되진 않지만 해답을 구하는 사람들에게 답이 될 수 있을 것 같아 글을 남기려고 한다. 단순하게 콘솔창에 정해진 문자열을 출력하는 문제이다.
