@@Joeadamu all my change does is use enumeration values from 1 to N instead of 0 to N-1. You also remove the " + 1" from the print call. Everything else remains unchanged. In this case it is a small improvement. In more complicated cases it can make the code noticeable clearer and reduce the chances of off by one errors.

Understanding how the code is structured is more important than memorizing functions. Being skilled in web searching and utilizing forums such as stack overflow are probably more useful than memorizing. Every coder searches for definitions or asks forums when they get stuck.

For the sum function, there is a cool thing you can do with the start argument. You can put any type that support the + operator. So for example if you want to flatten a list of list you can pass it with start=[] and it will get the job done

What is the advantage of map and filter functions, the same can be achieved with single line list_comprehension aswell. Curious to know what are the added advantages of using these map & filter functions. My approach for the items discussed in the video are : strings = ["my", "world", "apple", "pear"] l_comp = [len(i) for i in strings] print(l_comp) l_append = [i + "s" for i in strings] print(l_append) l_filterd = [i for i in strings if len(i) >4] print(l_filterd)

@TechWithTim
@TechWithTim 3 месяца назад
It has nothing to do with “looking good” it’s about utilizing the context manager for safety when operating with a file. It has a real utility in that it catches and resolves and file reading/writing errors automatically for you and ensures the file is closed correctly regardless of what you do. That’s why you use it.

No thanks... Working on a computer for a living seems like it is going to become completely obsolete in less than 5 years. Why spend time learning useless things... Does anyone use cursive writing any more? It used to be the optimised form of communication.. But I would argue that every second I was taught how to cursive write was a waste of time and energy that could have been spent on more useful fundamental skills.. Now learning AGI Command prompts.. That seems to be where the future is headed.. My first computer was a MS Dos. Using functions like this used to be how it was done. But certainly not for much longer..

As a coder who has used several AI code tools I have absolutely no fear for my job given the quality of the code they produce. Nor are they likely to get notably better in the future as throwing more training data at them leads to diminishing returns. Even if you can get it to produce the right code, you need to understand what it has produced to know it's right. AI has potential to be a useful aid but it's massively over hyped right now so all the startups can get that sweet VC cash.
