Student's t CDF for integer df >= 1, evaluated at t. Closed-form finite sum from Abramowitz & Stegun 26.7.7-8.

A strategy for :class:`python:zoneinfo.ZoneInfo` objects. If ``no_cache=True``, the generated instances are constructed using :meth:`ZoneInfo

Called when a value has been either added to or deleted from a key in the underlying database store. The possible values for ``event`

Return ``(op, bound)`` for filter conditions like ``partial(op, bound)``, with a single positional argument to one of the five comparison operator

Return a strategy for any value of the given dtype. Values generated are of the Python scalar which is :xp-ref:`promotable <type_promotion.ht

Narrow [min_value, max_value] to satisfy the condition ``func(arg, x)``. ``shift(value, steps)`` moves value by that many of the smallest represe

Inverse of :func:`_float_to_position` on the integer-valued range. Always returns an integer-valued, non-negative float.

Classify the values a timezones= strategy can generate: "none" if only None, "aware" if only tzinfo instances, or "unknown" if we can't tell.

Helper: run _try_inline_lambda and return the printer output, or None.

A copy of mock_xp with the given attributes removed.

Return a strategy for array shapes (tuples of int >= 1). * ``min_dims`` is the smallest length that the generated shape can possess. * ``max_

The number of bytes required to represent an n-bit number. Equivalent to (n + 7) // 8, but slightly faster. This really is called enough times

Recalculates is_exhausted if necessary, and then returns it. A node is exhausted if: - Its transition is Conclusion or Kille

Checks that value is either unspecified, or a valid integer. Otherwise raises InvalidArgument.

When introducing a rule in a RuleBasedStateMachine, this function can be used to mark bundles from which each value used in a step with the gi

This function tests whether the given datetime can be round-tripped to and from UTC. It is an exact inverse of (and very similar to) the dateutil

A deferred strategy allows you to write a strategy that references other strategies that have not yet been defined. This allows for the easy d

Return an iterable over all values matching this key.

Creates a strategy which can generate any value of the given dtype. Compatible parameters are passed to the inferred strategy function while

This is identical to the sets function but instead returns frozensets.

Inverse of char_in_shrink_order.

Performs some preliminary reductions that should not be repeated as part of the main shrink passes. The main reason why these can't b

Prefer known-FTZ modules, then top-level packages, then alphabetical.
