I am a newbie in data analysis stuff. I am trying to analyse a dataset using python. 
- I want to count no. of 1s in survived column
- No. of male , female in Sex column
PassengerId  Survived  Pclass   Sex
    0            1         0       3   male
    1            2         1       1   female
    2            3         1       3   male
    3            4         1       1   female
    4            5         0       3   male
I tried groupby() but its giving error.
In[88]   titanic_data.groupby('Survived') 
 Out[88] <pandas.core.groupby.DataFrameGroupBy object at 0x000000000BFFE588>
 
Please suggest solution
