Fix ModuleNotFoundError in football_final.py and misnamed weather function

[realpython-bot]

Found while reviewing a content update to Python Practice Problems: Parsing CSV Files.

The bug: full_code/football_final.py does not run

File "full_code/football_final.py", line 14, in <module>
    import csv_reader
ModuleNotFoundError: No module named 'csv_reader'

This folder only ever shipped csv_parser.py — there is no csv_reader.py in the tree, and there is none in the tutorial either. The article's own final listing imports csv_parser, so the module name here was simply wrong. Anyone downloading the materials and running the final football solution hits this immediately. Reproduced on current master before the fix.

Two call sites: the import at line 14 and the csv_reader.get_next_result(...) reference at line 25.

Also: get_name_and_avg → get_day_and_avg in weather_final.py

That function returns day_number — never a name:

def get_day_and_avg(day_stats):
    day_number = int(day_stats["Day"])
    avg = (int(day_stats["MxT"]) + int(day_stats["MnT"])) / 2
    return day_number, avg

weather_v2.py, two steps earlier in the same narrative, already calls it get_day_and_avg; the final file silently renamed it. The matching fix is going into the article in the same pass, so the two stay in sync.

Its sibling get_name_and_diff in football_final.py is deliberately left alone — that one really does return a team name.

Verification

• Reproduced the ModuleNotFoundError on unmodified master.
• After the change, both football_final and weather_final import cleanly.
• The folder's pytest suite passes 16/16 under Python 3.14 with pytest 9.1.1 and pandas 3.0.5.

Known, not fixed here

README.md still shows a console block claiming Python 3.7.1, pytest-6.2.1, py-1.10.0, pluggy-0.13.1. That's stale against the toolchain the article now documents, but refreshing it means regenerating the sample output, which is a bigger change than this fix — worth a follow-up.
