When your apprentice baker knows all the procedures involved in baking bread, such as finding the ingredients on the shelves, finding the pots and pans, mixing ingredients, and operating the oven, you can assign other tasks that use those same procedures. Baking bread involves combining ingredients in a bowl, so if you need to combine ingredients for another recipe, the apprentice already knows how to do that. So when you want to explain how to make cookies, you can now say "combine sugar, flour, and butter in a bowl" without explaining where to find the bowls or the sugar.
REMEMBER In Python, after you've written a program to do something, you can import it into another program. So the more you work with Python, the faster you'll be able to write programs.
