If the last word in a sentence is within quotation marks, the period is only placed inside the quotation marks if it is part of the material being quoted. If the period is not part of the quoted material it is left outside. The same applies for other commas, question marks and exclamation marks. This practice is known as '''logical punctuation'''. In the United States and Canada, it is more common to leave periods and commas inside the quotation marks irrespective of whether it is part of the material being quoted. This practice is known as '''traditional punctuation'''.
