TimeDuration.equals(other, rtol=None, atol=None, verbose=None, traceback=False)[source]

True if two time durations are equal.

New in version 1.0.

The object to compare for equality.

rtol: float, optional

The relative tolerance for all numerical comparisons, By default the value returned by the rtol function is used.

atol: float, optional

The absolute tolerance for all numerical comparisons, By default the value returned by the atol function is used.

verbose: int or str or None, optional

If an integer from -1 to 3, or an equivalent string equal ignoring case to one of:

  • 'DISABLE' (0)

  • 'WARNING' (1)

  • 'INFO' (2)

  • 'DETAIL' (3)

  • 'DEBUG' (-1)

set for the duration of the method call only as the minimum cut-off for the verboseness level of displayed output (log) messages, regardless of the globally-configured cf.log_level. Note that increasing numerical value corresponds to increasing verbosity, with the exception of -1 as a special case of maximal and extreme verbosity.

Otherwise, if None (the default value), output messages will be shown according to the value of the cf.log_level setting.

Overall, the higher a non-negative integer or equivalent string that is set (up to a maximum of 3/'DETAIL') for increasing verbosity, the more description that is printed to convey information about the test for contiguity.

traceback: deprecated at version 3.0.0

Use the verbose parameter instead.


Whether or not the two instances are equal.


>>> t = cf.TimeDuration(36, 'calendar_months')
>>> u = cf.TimeDuration(3, 'calendar_years')
>>> t == u
>>> t.equals(u, verbose=2)
TimeDuration: Different durations: <CF Data: 36 calendar_months>, <CF Data: 3 calendar_years>
