Navigating a Python list within a while loop

In this video tutorial I look at how the while loop can be used to navigate over a Python lists. This allows for highlighting the indexed nature of a Python list. In addition it explains the IndexError: list index out of range

Best description I've gotten for list with while look yet. Thanks!

Hello is the "[i]" part of the print statement explained in previous videos, I can't find it. I would like to know its function since we are already asking the program to ouput the list by name which will print the same numbers as well. Ok so after running a variation I see that without the [i] part to ask the interpreter to print the number by index order you will just get a print out of the whole list not every number by order. so without "[ i ]" CODE: list_a = list([23,71,8]) i = 0 while i

[@johnphilipjones]

Use [i] to access individual elements of the list. Regards Phil

[@jaredbmorris1498]

what if your list is composed of strings and not integers? I keep getting this error: TypeError: '

[@johnphilipjones]

I would need to see the code to answer this. Please paste it as a comment to this reply. Best wishes Phil

Hello, here we have two lists a = [1,2,3] and b = [1,2,3], why do both object a and b has a different id, why not the same id? Although the elements 1, 2 and 3 are objects of integer class, they will have same id.

[@johnphilipjones]

Have a look at the following video it shows how the id() works with lists: kzbin.info/www/bejne/mIi3qWmLiLRmfZI Best wishes Phil

[@lakeguy65616]

I'm confused. this [] defines a list and () creates a tuple and the list() recasts a collection object into a list. so list([a collection]) seems redundant to me. you have list inside a tuple, then recast into a list. what am I not seeing? Outstanding videos!

Data types can be cast into other date types (i.e. changed). Different data types can be processed with different degrees of efficiency. You would frequently change the data type to ensure that your code ran as efficiently as possible (i.e. faster and/or take up less memory). In addition data types can be mutable or immutable. You may for example want to process the data without changing the data in the data structure (i.e. sum all the data). In which case choosing an immutable data type (structure) would offer the best protection against change. Best wishes Phil
