如何计算数据框列中的出现次数？

Question

This is a sample of my df:

Paid    Scheduled   tfl modeName
True    True    True    bus
True    True    True    cable-car
True    True    False   coach
False   False   False   cycle
True    False   True    cycle-hire
True    True    True    dlr

I need to have in another dataframe only the modeName which are true in Paid and Scheduled:

modeName     
bus
cable car
coach
dlr

And count how many are paid AND scheduled. I got this with this code:

df1_transporte = df1.isFarePaying.values.sum() & df1.isScheduledService.values.sum()

df1_transporte

But how to get the modeNames that have both conditions?

Answer 1

Using pandas,

you can use df[(df['Paid']==True) & (df['Scheduled']==True)] to generate a dataframe with only the rows where 'Paid' and 'Scheduled' are True.
