Comment 3 for bug 1819751

pytz/tests/test_docs.py also fails on Python 3.8 because repr(datetime.timedelta) changed to include parameter names. Example of failure:

File "pytz/tests/../../README.txt", line 213, in README.txt
Failed example:
    tz.dst(normal)
Expected:
    datetime.timedelta(0, 3600)
Got:
    datetime.timedelta(seconds=3600)

I propose the following fix which should work on all Python versions:
