Python Strings :

The raw_input and "Hello, " + name + "!"

Let’s go for the "Hello" part first and leave raw_input for later.

The first program in this chapter was simply print "Hello, world!"

But what is "Hello, world!"? It’s called a string (as in “a string of characters”).

Strings are found in almost every useful, real-world Python program and have many uses.

Their main use is to represent bits of text, such as the exclamation “Hello, world!”
