Live template for zip function (python) 关注

Hi,

I'm trying to write a template for the zip command.

The template looks like this:

for $VAR1$,$VAR2$ in zip($ITERABLE1$,$ITERABLE2$):
    $END$

And in the edit variables I wrote as follow:

When I try to invoke it, the first variable (i.e. VAR1) is auto-completed successfully. However VAR2 does not, nor can I use the arrow key/tab to jump to ITERABLE2.

I'm using pycharm professional 3.7

Thanks for any help!
