I have a script written in vimscript-python, e.g.:
function! MyFunction()
python3 << EOF
if <condition>:
return
print('Hello world')
EOF
endfunction
I want to add a check in the beginning of the script and if a check fails, the functions execution should be terminated. I tried using return and exit(), but return throws SyntaxError and exit() throws SystemExit exception. I want to stop execution without any errors.
