Being a "newbie" to python, I really like the documentation that explains what the code is doing, as well as the actual efficiency of the code. I'm still learning how to use some of the language (map, filter), and such examples and documentation are really helpful in understanding and using these to improve my own code writing.

maybe not the clearest one... but at least original 😉

I thought that such construction required a lambda function to access the elements of the list, i.e. filter(lambda x: x.isdigit(),list). But you can use the default function str.isdigit and str will be the elements of list. Great!
