# numpy.less() in Python

Last Updated : 08 Mar, 2024

The numpy.less() : checks whether x1 is lesser than x2 or not. Syntax :

`numpy.less(x1, x2[, out])`

Parameters :

```x1, x2 : [array_like]Input arrays. If x1.shape != x2.shape, they must be
out    : [ndarray, boolean]Array of bools, or a single bool if x1 and x2 are scalars.```

Return :

`Boolean array indicating results, whether x1 is lesser than x2 or not.`

Code 1 :

## Python

 `# Python Program illustrating ` `# numpy.less() method ` `  `  `import` `numpy as geek  ` ` `  `a  ``=` `geek.less([``8.``, ``2.``], [``5.``, ``3.``]) ` `print``(``"Not equal : \n"``, a, ``"\n"``) ` ` `  `b ``=` `geek.less([``2``, ``2``], [[``1``, ``3``],[``1``, ``4``]]) ` `print``(``"Not equal : \n"``, b, ``"\n"``) ` ` `  `a ``=` `geek.array([``4``,``2``]) ` `b ``=` `geek.array([``6``,``2``]) ` ` `  `print``(``"Is a lesser than b : "``, a < b) `

Output :

```Not equal :
[False  True]

Not equal :
[[False  True]
[False  True]]

Is a lesser than b :  [ True False]]```

Code 2 :

## Python

 `# Python Program illustrating ` `# numpy.less() method ` `   `  `import` `numpy as geek  ` `  `  `# Here we will compare Complex values with int  ` `a ``=` `geek.array([``1j``,``2``]) ` `b ``=` `geek.array([``1``,``2``]) ` `  `  `# indicating 1j is lesser than 1 ` `print``(``"Comparing complex with int : "``, a < b) ` ` `  `# indicating 1j is lesser than 1 ` `d  ``=` `geek.less(a, b) ` `print``(``"\n Comparing complex with int  .less() : "``, d) `

Output :

```Comparing complex with int :  [ True False]

Comparing complex with int  .less() :  [ True False]```

Code 3 :

## Python

 `# Python Program illustrating ` `# numpy.less() method ` `   `  `import` `numpy as geek  ` ` `  `# Here we will compare Float with int values ` `a ``=` `geek.array([``1.1``, ``1``]) ` `b ``=` `geek.array([``1``, ``2``]) ` `  `  `# indicating 1.1 is greater than 1 ` `print``(``"Comparing float with int : "``, a < b) ` ` `  `# indicating 1.1 is greater than 1 ` `d  ``=` `geek.less(a, b) ` `print``(``"\n Comparing float with int using  .less() : "``, d) `

Output :

```Comparing float with int :  [False  True]

Comparing float with int using  .less() :  [False  True]```
