# numpy.square() in Python

numpy.square(arr, out = None, ufunc ‘square’) : This mathematical function helps user to calculate square value of each element in the array.

Parameters :

```arr  : [array_like] Input array or object
whose elements, we need to square.
```

Return :

```An array with square value of each array.
```

Code #1 : Working

 `# Python program explaining ` `# square () function ` ` `  `import` `numpy as np ` ` `  `arr1 ``=` `[``1``, ``-``3``, ``15``, ``-``466``] ` `print` `(``"Square Value of arr1 : \n"``, np.square(arr1)) ` ` `  `arr2 ``=` `[``23` `,``-``56``] ` `print` `(``"\nSquare Value of arr2 : "``, np.square(arr2)) `

Output :

```Square Value of arr1 :
[     1      9    225 217156]

Square Value of arr2 :  [ 529 3136]
```

Code #2 : Working with complex numbers

 `# Python program explaining ` `# square () function ` ` `  `import` `numpy as np ` ` `  `a ``=` `4` `+` `3j` `print``(``"Square(4 + 3j) : "``, np.square(a)) ` ` `  `b ``=` `16` `+` `13j` `print``(``"\nSquare value(16 + 13j) : "``, np.square(b)) `

Output :

```Square(4 + 3j) :  (7+24j)

Square value(16 + 13j) :  (87+416j)```

Code #3 : Graphical Representation of numpy.square()

 `# Python program explaining ` `# square () function ` ` `  `import` `numpy as np ` `import` `matplotlib.pyplot as plt ` ` `  `a ``=` `np.linspace(start ``=` `-``5``, stop ``=` `5``, ` `                ``num ``=` `6``, endpoint ``=` `True``) ` `                 `  `print``(``"Graphical Representation : \n"``, np.square(a)) ` ` `  `plt.title(``"blue : with square\nred : without square"``) ` `plt.plot(a, np.square(a)) ` ` `  `plt.plot(a, a, color ``=` `'red'``) ` `plt.show() `

Output :

```Graphical Representation :
[ 25.   9.   1.   1.   9.  25.]
