In the following example, we loop through a list of numbers, and use the variable digit to hold each number in turn: Strings in Python are considered “sequences” — they can be iterated over, and the ...

Why write ten lines of code when one will do? From magic variable swaps to high-speed data counting, these Python snippets will transform your code.

But in many cases, it doesn’t have to be an either/or proposition. Properly optimized, Python applications can run with surprising speed—perhaps not as fast as Java or C, but fast enough for web ...
