A list can be joined using together as a string using the stynax:
a_list = [1,2,3]
a_string = " ".join(a_list)
print("A string:", a_string)Which will output:
A string: 1 2 3
Looking at how split works in Python, a_string.split(delimiter),
and how join works in other languages like JavaScript it's easy to confuse it as working in Python as list.join(delimiter).
A way to help rationalize this syntax is to not think of join as transforming a list into a string,
but rather as a function that places the delimiter string in-between elements of a list.
