# concatenating strings just means combining strings together
# it is used to add one string to the end of another
# below are two exmaples of how concatenation can be used
# to output 'Hello World':
# example 1:
hello_world = "Hello" + " World"
print(hello_world)
>>> Hello World
# example 2:
hello = "Hello"
print(hello + " World")
>>> Hello World
