Grouping a column by boolean comparison

Vote count:

0

I have a dataframe in Pandas that has the following format (with a bunch of other columns as well)

   chip  WL     ok
0     1   1   True
1     1   2   True
2     1   3   True
3     1   4   True
4     2   1  False
5     2   2   True
6     2   3   True
7     2   4   True

I want to group by chip, count the number of WLs for each chip, and do a logical and on each value in the ok columns. The expected output should look like this:

   chip  WLs     ok
0     1   4    True
1     2   4   False

How do I do this?
