Classic Hello World.py

# You are given a method called main, make it print the line Hello World!, (yes, that includes a new line character at the end) and don't return anything

# Note that for some languages, the function main is the entry point of the program.

# Here's how it will be tested:

#     Solution.main("parameter1", "parameter2","parametern")

# Hints:

#     Check your references
#     Think about the scope of your method
#     If you still don't get it probably you can define main as an attribute of the Solution class that accepts a single argument, and that only prints "Hello World!" without any return.

class Solution:
    def __init__(self, a, b):
        return self
    def main(self):
        print("Hello World!")
