From 3a418c8b5dd733598ace7ccfdc6be43b11821d1d Mon Sep 17 00:00:00 2001 From: Matt McKay Date: Tue, 1 Sep 2026 15:39:25 +1000 Subject: [PATCH] doubts_or_variability: drop the pandas-datareader install nothing imports The lecture deliberately reads FRED's CSV endpoint (its own comment says so) and never imports pandas_datareader; only the install line survived the switch. Removing it changes no output and shrinks the build environment. The two intro lectures in the same inventory were cleaned up in QuantEcon/lecture-python-intro#803, so this is the last of the three. See QuantEcon/data-lectures#26.
