从 python class 创建 vim 实例？

Question

I'm calling a python function that returns a dictionary, and that works but I was just wondering if there was a way to create an instance like this in vimscript m.multi(3), m.div(20,5) . This is just an example, not sure about the last 2 lines.

python3 <<EOF
class Multiply:
    @staticmethod
    def myfunc(n):
        print("Answer is:", n * n)
EOF
python3 m = Multiply
python3 vim.command(f"let multi={m}")
call multi(4)

Answer 1

Define Multi as a VimScript function and call python inside it:

python3 <<EOF
import vim

class Multiply:
    @staticmethod
    def myfunc(n):
        print("Answer is:", n * n)
EOF

" Single global instance
python3 m = Multiply()

function! Multi(i)
    " int() is required as vim.eval() returns a string even for int arg
    python3 m.myfunc(int(vim.eval('a:i')))
endfunction

Test: :call Multi(4)

Answer 2

I don't think it's possible, leave object oriented stuff in python code.
