Python | Numpy np.ma.common_fill_value() method

With the help of `np.ma.common_fill_value()` method, we can get the common filling values from both the masked array if same by using `np.ma.common_fill_value()` method.

Syntax : `np.ma.common_fill_value(array1, array2)`
Return : Return the common filling value from both the arrays.

Example #1 :
In this example by using `np.ma.common_fill_value()` method, we are able to get the common filling values from both the masked arrays.

 `# import numpy ` `import` `numpy as np ` ` `  `x ``=` `np.ma.array([``1``, ``2``, ``3``], fill_value ``=` `1``) ` `y ``=` `np.ma.array([``7``, ``8``, ``9``], fill_value ``=` `1``) ` ` `  `# using np.ma.common_fill_value() method ` `gfg ``=` `np.ma.common_fill_value(x, y) ` ` `  `print``(gfg) `

Output :

1

Example #2 :

 `# import numpy ` `import` `numpy as np ` ` `  `x ``=` `np.ma.array([[``1``, ``2``], [``2``, ``1``]], fill_value ``=` `2``) ` `y ``=` `np.ma.array([[``1``, ``5``], [``5``, ``1``]], fill_value ``=` `5``) ` ` `  `# using np.ma.common_fill_value() method ` `gfg ``=` `np.ma.common_fill_value(x, y) ` ` `  `print``(gfg) `

Output :

None
