I program for over 20 years. I just closed some tabs from yesterday:
"how to create directory in python"
"concat lists python"
"load 2 models tensorflow"
"how set pythonpath"
and some others.
And yes. I have a masters degree in informatics.
You don't need to learn things that you rarely need & are just 1 duckduckgo away by heart. Knowing that they exist and what to search for is sufficient.
Important are the thing you cannot search. Concentrate on those.
