Two years ago, Eckel gave a keynote address at the 9th International Python Conference entitled "Why I love Python." He presented ten reasons he loves programming in Python in "top ten list" style, starting with ten and ending with one.

In this interview, which is being published in weekly installments, I ask Bruce Eckel about each of these ten points. In this installment, Bruce Eckel explains why he feels Python is "about him," how minimizing clutter improves productivity, and the relationship between backwards compatibility and programmer pain.

This makes me feel a ton better, because I can't remember this type of stuff either:

They say you can hold seven plus or minus two pieces of information in your mind. I can't remember how to open files in Java. I've written chapters on it. I've done it a bunch of times, but it's too many steps. And when I actually analyze it, I realize these are just silly design decisions that they made. Even if they insisted on using the Decorator pattern in java.io, they should have had a convenience constructor for opening files simply. Because we open files all the time, but nobody can remember how. It is too much information to hold in your mind.

Another number that used to be bandied about is that programmers can produce an average of ten working lines of code per day. Say I open up a file and read in all the lines. In Java, I've probably already used up my ten working lines of code for that day. In Python, I can do it in one line. I can say, "for line in file('filename').readlines():," and then I'm ready to process the lines. And I can remember that one liner off the top of my head, so I can just really flow with that.

Real interesting interview.
