Question

To compile a python file from shell, one can type

python -O filename.py

In a situation where there are many files, this can be tasking. How can I use this command or any other command to compile all the .py files in a folder at once.

Answer 1

Depending on how Python is written in this regard,

python -O *.py

might suffice. Otherwise

for /f in %x in (*.py) do python -O "%x"
