2 problems and a question

The problems are: Import “flet” could not be resolved, no module named flet and how do I execute “>>>” in VScode?. How to resolve these errors?

You need to install flet, I suggest you start with the documentation (or perhaps the Python docs if you are new to the language).

You don’t need to execute >>>, that is the prompt for an interactive python session. If you see an example that starts with >>> it is meant to be run in an interactive terminal, like this:

~$ python                            
Python 3.10.10 | packaged by conda-forge | (main, Mar 24 2023, 20:08:06) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print("hello world")
hello world
>>> quit()
