To retrieve all rows from a multi-indexed #Python #Pandas data frame or series based on the outermost index, use "loc":

(
pd
.read_parquet('/Users/reuven/Data/nyc_taxi_2025-11.parquet')
.groupby(['passenger_count', 'VendorID'])['total_amount'].mean()
.loc[1.0]
)

AI played a huge role in helping me understand the methods and work through difficult cases. My biggest lesson: cleaning data requires judgment, not just code.

For my next dataset, I hope to do most of the work independently and use AI mainly for guidance. 3/3

Day 49 🚀

Learned today:

→ C: strings, gets, puts, fgets
→ Pandas: read_csv(), selecting data with loc, iloc, at, iat
loc/at use labels, iloc/iat use positions.

Using resample in #Python #Pandas? You'll want a list of "offset aliases," the codes that let you specify units.

Some are surprising, such as "ME" and "MS" for "month end" and "month start".

في Pandas 3.0، أصبحت Copy-on-Write السلوك الافتراضي.

تعديل كائن مشتق من DataFrame لا يغيّر الأصل تلقائيًا، وChained Assignment ليس طريقة صالحة لتعديله.

استخدم .loc لتحديد الصفوف والأعمدة في عملية واحدة.
