Timedelta not parsing ISO-8601 strings properly · Issue #29773 · pandas-dev/pandas (original) (raw)

Code Sample, a copy-pastable example if possible

pd.Timedelta("P0DT1H") Timedelta('0 days 00:00:00')

and

pd.Timedelta("PT1H")

KeyError Traceback (most recent call last) pandas/_libs/tslibs/timedeltas.pyx in pandas._libs.tslibs.timedeltas.parse_timedelta_unit()

KeyError: ''

During handling of the above exception, another exception occurred:

ValueError Traceback (most recent call last) in () ----> 1 pd.Timedelta("PT1H")

Problem description

The ISO strings should be parsed correctly and provide valid output
as described here and shown here

Expected Output

First example and second example should have output

Timedelta('0 days 01:00:00')

Output of `pd.show_versions()`

I had the same outputs locally and on google cola
