The current

I'd suggest the following change to the docstrings for
the exec* functions, because I think it's quite easy to
get bitten:

execv(...)
    execv(path, args)
    
    Execute an executable path with arguments,
replacing current process.
    
            path: path of executable file
            args: tuple or list of strings (NOTE: the
first argument is
                     analoguous to sys.argv[0], *not*
sys.argv[1]!)

instead of:

execv(...)
    execv(path, args)
    
    Execute an executable path with arguments,
replacing current process.
    
            path: path of executable file
            args: tuple or list of strings

This is covered in the Library Manual.
Docstrings aren't meant to be complete, just quick overviews
of what the functions do.

Please point to it. Is it different from help(os.execvp)?

It is still unclear how to treat the args argument. Based on my own tests it seems that both versions are working.

os.execvp(cmd[0], cmd)
os.execvp(cmd[0], cmd[1:])
