Thinking like a computer

In programming, one crucial thing to remember, before everything else, is to think like a computer. In every line of code in your program, something happens. Just like a computer, do everything in steps.

If one line says:

text = "Hello World"

then think that.

Then think of the next line:

print(text)

and so on in small, discrete steps. Follow every line like a stepping stone.

Doing so can save you a lot of testing your app, but make sure to test it every once in a while, frameworks and operating systems can be quirkier than you expect.
