get dataframe row count based on conditions

I want to get the count of dataframe rows based on conditional selection. I tried the following code.

print df[(df.IP == head.idxmax()) & (df.Method == 'HEAD') & (df.Referrer == '"-"')].count()

output:

IP          57
Time        57
Method      57
Resource    57
Status      57
Bytes       57
Referrer    57
Agent       57
dtype: int64

The output shows the count for each an every column in the dataframe. Instead I need to get a single count where all of the above conditions satisfied? How to do this? If you need more explanation about my dataframe please let me know.
