These four lines look nice.

I think these tests would fit better in pandas/tests/scalar/timestamp/test_timestamp.py, which already contains tests of Timestamp.tz_localize and Timestamp.tz_convert.

One other thought: you could add a case where freq is None, or possibly add an assertion to an existing test in test_timestamp.py.

Can you use the tz_naive_fixture. Ensures we also test tz_localize(None) as well.

Just assert the Timestamps are equal. IIRC the freq will be compared as well.

but i assume t1.tz_localize(pytz.utc) is tz-aware while t1 is tz-naive ? @mroeschke

I guess as mentioned below. I was incorrect in assuming the freq would be compared as well.

Don't need to import this. Just the string 'UTC' will automatically use pytz.UTC

I think you need to assert that the freq attributes are equal, as opposed to comparing the timestamps.

Timestamp freq values do not influence equality comparisons or hash values. Here's a quick example that shows this:

>>> t1 = pandas.Timestamp('2018-01-01 10:00', freq='H') 
>>> t2 = pandas.Timestamp('2018-01-01 10:00', freq='T') 
>>> t1 == t2
True
>>> t1.freq == t2.freq
False

ahh, nice catch!!

t1 = pd.Timestamp('2018-01-01 10:00', freq='H')
t2 = pd.Timestamp('2018-01-01 10:00')])

and t1 != t2! thanks! @nmusolino

Could you specify Timestamp.tz_localize and Timestamp.tz_convert? Then you can remove the additional Timestamp towards the end.

do not compile.

The long term solution is to update the cython files to the next
language level, but this is a stop-gap to keep pandas building.

* BUG: Fix regression on DataFrame.replace for regex

The commit ensures that the replacement for regex is not confined to the 
beginning of the string but spans all the characters within. The 
behaviour is then consistent with versions prior to 0.24.0.

One test has been added to account for character replacement when the 
character is not at the beginning of the string.
