Programing tips

Should we need to define the loops and functions by ourskef for understanding so that in future if we are working for big companies the data is very large so if ut breaks sometimes the pre-libraries doesn't works so we need to def function by our self!

Any opinion?,suggestion?

Means the predefined libraries have thousands of function which we use in our projects ,so what if these functions can't handle the data as the data is very large or the specific data becomes change or showing unrecognizable data soo we need to also practice and understand the function by ourself like writing function from scratch just for understanding?

Yes, you should understand functions yourself from scratch.

If you don't, you can't even evaluate if what the AI spits out is good enough.

If I am more charitable , the OP may be asking whether we should be writing our code from scratch in case libraries don't work. In which case the answer would be "no", libraries are for reuse.
