This is an interesting question. Here are my thoughts on it.

- If you can identify the design pattern that your program might fall
  into, it would be best. Most often by reading and modelling after
  the existing ones or using libraries we tend to use the design
  patterns. So adopting the pattern might be a second or a later step.

- Write the Problem Definition in English/Native language.

- Write the Answer in English/Native language.If the Answer is more
  than one step. Write down in to distinct points. If there are any
  interactions, note it down.

- Give function names for your answers and draw the connection. While
  using python, it is not necessary to settle on the parameters in
  the first shot, you come back to it later.

- Make the first small program which does something and then improve
  it to do something more.

You can do it all in any editor or in piece of paper.

HTH,
