Luckily, Python is an excellent language for writing readable programs. " stuff about? Let’s tackle the "Hello" part first and leave raw_input for later. " It is customary to begin with a program like this in programming tutorials. The problem is that I haven’t really explained how it works yet. "? 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. ' There is one thing that may be a bit surprising about this example, though: when Python printed out our string, it used single quotes, whereas we used double quotes.
That wasn’t too hard. Well, what about this: >>> 53672 + 235253 288925 Still not impressed? Admittedly, this is pretty standard stuff. ) All the usual arithmetic operators work as expected—almost. 0): >>> 1/2 0 9 10 CHAPTER 1 ■ INSTANT HACKING: THE BASICS What happened here? One integer (a nonfractional number) was divided by another, and the result was rounded down to give an integer result. This behavior can be useful at times, but often (if not most of the time), you need ordinary division. What do you do to get that?
When you program a computer, you are essentially describing an algorithm in a language the computer can understand, such as Python. Such a machine-friendly description is called a program, and it mainly consists of expressions and statements. Expressions: An expression is a part of a computer program that represents a value. For example, 2+2 is an expression, representing the value 4. Simple expressions are built from literal values (such as 2 or "Hello") by using operators (such as + or %) and functions (such as pow).
