How To Count Data In A DataFrame - Pandas For Machine Learning 5

I have learned quite a bit from you in your Django blog series thanks for your knowledge.

I cannot express how helpful your Django Wednesday playlist was for me. Myself and another dev were asked to create an application in 2 weeks that could handle a variety of functions. All of which were covered in your series. I am not even sure I will need your course material in the future, but I bought it anyway as a huge thank you for your wonderful content. Again, thank you!

Hi! I was wondering if you could link the data that you are using in the comments. Thanks!

Hi, for example I have a table, which I've got by left outer join:

person - vehicle

dad - car
dad - motorcycle
dad - bicycle
mom - car
mom - bicycle
son - None/NA/NaN/NaT

How to group by person and count with condition (car and motorcycle)?

When I use for example:
df = df.groupby(['person'])['vehicle'].apply(lambda x: x[x == 'car'].count())

But I can't use a list in condition lambda x: x[x in ['car']], pandas says:
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()

Your videos are very great, plz upload videos related to tensor flow and pytorch

Thanks a lot! I like your videos, its short, funny! That's what I'm talking about!

Hi, I am new here, but learning a lot from your videos. Would be very helpful if you could tell how to import this particular dataset from github.
