Move comments to their own line.
Previously the inline comments would wrap onto their own line which looked terrible.

An important thing to note is that you can only `str.join` strings. For a list of ints, you must convert each element to a string before joining. ```py integers = [1, 3, 6, 10, 15] -print(", ".join(str(e) for e in integers)) # Prints '1, 3, 6, 10, 15' +print(", ".join(str(e) for e in integers)) +# Prints '1, 3, 6, 10, 15' ``` |
