Love the channel. FYI, the key in the .sort() method doesn't have to be a lambda function. Any function will work including built-ins and functions you write yourself. Both of your examples would have worked with people.sort(key=str.lower) and people.sort(key=len)

So I'm iterating through a list of IP addresses and a module is used to attempt to connect via SSH. Some IP addresses I know will fail and will raise a timeout error. How do I iterate to the next item in the list and continue when this happens? Also the list is created by an excel sheet.

Although if you add some intst there, it wont give you an error, so I dont get the [str] part, its just a hint to increase readability ?? Thx in advance.

@@Indently The class *list* in Python implements what's called arrays in almost every other language and data structures books (more precisely dynamic arrays, C++ call them vectors but that's an horrible choice all of its own). If you're teaching programming with Python, it's a constant pain to every so often catch yourself referring to lists when you meant arrays just because the chosen language didn't use the standard name. Not really important in most other contexts (a rose by any other name…).

clear empties your existing list object, while = [] creates a new empty list object. If you don't care about the particular object reference value, the differences are negligible in practice.

Correct. Python list sorting methods are stable, meaning that equal keys preserve the original order. The video was incorrect on that point.
