pd.query method question

[PolskaYBZ]

Hi,

I have a dataframe for which I want to create a filter.
I know you can do it via Boolean indexing, but now I found as well the pd.query method.

DF :

  col1  col2
0     Jan     3
1     Feb     4
2     Mar     5

df.query('col1 == "Feb"')

would normally work, but I wonder how you can filter on 2 columns as

df.query('col1 == "Feb" and col2 == "Mar"')

doesnt seem to work.

Thanks!
