Lesson 6 of 7
Read a real CSV
CSV is the universal exchange format of spreadsheets. Python's csv module reads it cleanly (better than a naive split).
csv.reader(io.StringIO(text)) walks the lines; next(reader) skips the header row.
import csv, io
reader = csv.reader(io.StringIO(data))
next(reader) # skip the header
for row in reader:
print(row[0])🎯 Your goal
Read DATA with csv.reader: skip the header with next(), collect all rows into the rows list, then print the number of rows.
