I just started learning python, in the process of learning i came across multiple functions which have different work, but i forget majority of them after a certain point, i know how they work but just don't remember the syntax, ik we can use google whenever we want to know about any specific function, but the main issue is interviews, there u cant say that ik how it works but i just don't remember the syntax

After searching a lot about it, i came to this conclusion:
U can write whatever u r seeing and think it might be useful, now comes the remembering part, so solve questions for them and u will understand what's important and what's not, and those concepts which repeat more , means they are more important and u will eventually learn them by solving questions as they will keep repeating.

Is my conclusion right? Or it needs some correction.
