Quotes About Coding

The name used as the assignment target in a for header line is usually a (possibly new) variable in the scope where the for statement is coded. There's not much unique about this name; it can even be changed inside the loop's body, but it will automatically be set to the next item in the sequence when control returns to the top of the loop again.

On a related note, you can also code multiple __init__ methods within the same class, but only the last definition will be used; see Chapter 31 for more details on multiple method definitions.

As usual in Python, it's important to understand fundamental principles like those illustrated in the prior section. Python's "batteries included" approach means you'll usually find precoded options as well, though you still need to know the ideas underlying them to use them properly.

as this little function isn't needed elsewhere, it was written inline as a lambda.

any function that contains a yield statement is turned into a generator function.

If you wish to use this method, you can avoid loops by coding instance attribute assignments as assignments to attribute dictionary keys. That is, use self.__dict__['name'] = x, not self.name = x; because you're not assigning to __dict__ itself, this avoids the loop:

give people a tool, and they'll code for a day; teach them how to build tools, and they'll code for a lifetime. This

The programmers of tomorrow are the wizards of the future. You're going to look like you have magic powers compared to everybody else.

The programmers of tomorrow are the wizards of the future.

The information encoded in your DNA determines your unique biological characteristics, such as sex, eye color, age and Social Security number.

I just think people have a lot of fiction. But, you know, I mean, the real story of Facebook is just that we've worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.

Repetition is the root of all software evil

Most programmers, even experienced ones, are poor judges of how code actually performs.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand.

A heuristic we follow is that whenever we feel the need to comment something, we write a method instead.

Life being what it is, you won't get your names right the first time. In this situation you may well be tempted to leave it—after all it's only a name. That is the work of the evil demon Obfuscatis; don't listen to him. If you see a badly named method, it is imperative that you change it. Remember your code is for a human first and a computer second. Humans need good names.

Remember that codes are more than a filing system. Every project needs a systematic way to store coded field data and a way to retrieve them easily during analysis.

As soon as we started programming, we found out to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.

code is prioritized above human interactions.

To think like a computer programmer, it helps to be lazy.)

Remember, though, that debugging is as much art as it is computer science [..]

One of the problems we've had is that the ICT curriculum in the past has been written for a subject that is changing all the time. I think that what we should have is computer science in the future - and how it fits in to the curriculum is something we need to be talking to scientists, to experts in coding and to young people about.

When you start a session in R, the variables you create are in the global environment .GlobalEnv
