★2.7, 3.4+ You can enclose string literals in Python in four types of quotation marks. Single and double quotation marks define single-line strings. Line breaks are not allowed within:

​ ​'Mary had a little lamb'​
​ ​"Mary had a little lamb"​

There is no difference whatsoever between single and double quotation marks in Python, unlike C/C++/Java (where single marks are used for individual characters and double marks are used for strings) or PHP (where double-quoted strings are interpreted but single-quoted strings are not). Should you use single or double quotation marks? It is up to you.

Triple-single and triple-double quotation marks define multiline strings. They can include literal line breaks.

​ ​'''Mary​
​ ​had a little​
​ ​lamb'''​
​ 
​ ​"""Mary​
​ ​had a little​
​ ​lamb"""​

And again, there is no difference whatsoever between triple-single and triple-double quotation marks. Use whatever you like. Just try to be consistent.
