Check as to whether the input is None or not.

Parameters:: x (Any) – Input to check.
Return type:: bool
Returns:: ret – True if x is not None, else False.

Examples

With Any input:

>>> x = None
>>> y = ivy.exists(x)
>>> print(y)
False

>>> x = ""
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = []
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = 1
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = "abc"
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = [1, 0, -1, 1]
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = ivy.array([1, 2, 3, 1.2])
>>> y = ivy.exists(x)
>>> print(y)
True

With a mix of ivy.Container and Any input:

>>> x = ivy.Container(a=None, b=None)
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = ivy.Container(a=None, b="")
>>> y = ivy.exists(x)
>>> print(y)
True

>>> x = ivy.Container(a=123, b="")
>>> y = ivy.exists(x)
>>> print(y)
True

Array.exists(self)#

ivy.Array instance method variant of ivy.exists. This method simply wraps the function, and so the docstring for ivy.exists also applies to this method with minimal changes.

Parameters:: self (Array) – input array.
Return type:: bool
Returns:: ret – True if x is not None, else False.

Examples

>>> x = ivy.array([1, 2, 3, 1.2])
>>> y = x.exists()
>>> print(y)
True

>>> x = ivy.array(None)
>>> y = x.exists()
>>> print(y)
True
