# Python Comments
    # Comments can be used to explain Python code.
    # Comments can be used to make the code more readable.
    # Comments can be used to prevent execution when testing code.

# Creating a Comment
    # Comments starts with a #, and Python will ignore them.

# This is a comment
print("Hello, World!")

    # Comments can be placed at the end of a line, and Python will ignore the rest of the line.

print("Cheers, Mate!") #print("Hello, World!")

    # A comment does not have to be text that explains the code, it can also be used to prevent Python from executing code.

print('----------------------------------------------------------------')
# Multi Line Comments
    # Python does not really have a syntax for multi line comments.
    # To add a multiline comment you could insert a # for each line.

#This is a comment
#written in
#more than just one line
print("Hello, World!")

    # Since Python will ignore string literals that are not assigned to a variable, 
    # you can add a multiline string (triple quotes) in your code, and place your comment inside it.
    # As long as the string is not assigned to a variable, Python will read the code, but then ignore it, and you have made a multiline comment.
