Strings what you use to represent text. Strings are a sequence of characters, enclosed in single quotes or double quotes. >> x = "hello" >> y = 'world' >> print x, y hello world There is difference between single quotes and double quotes, they can used interchangebly.

y = '''multi-line strings can be written using three single quote characters as well.
Methods are special kind of functions that work on an object. For example, upper is a method available on string objects. >> x = "hello" >> print x.upper()
> istrcmp('LaTeX', 'Latex') True > istrcmp('a', 'b') False
