# numpy.less () in Python

Arrays | NumPy | Python Methods and Functions

numpy.less (x1, x2 [, out]): checks if x1 is less than x2 or not.
Parameters :

`  x1, x2:  [array_like] Input arrays. If x1.shape! = X2.shape, they must be broadcastable to a common shape  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 program illustrating ` ` # numpy.less () method `   ` import ` ` numpy as geek ` ` `  ` a ` ` = ` ` geek.less ([` ` 8. ` `, ` ` 2. ` `], [` ` 5. ` `, ` ` 3. ` `]) ` ` print ` ` (` ` "Not equal:" ` `, a, ` ` "" ` `) `    ` b ` ` = ` ` geek.less ([` ` 2 ` `, ` ` 2 ` `], [[` ` 1 ` `, ` ` 3 ` `], [` ` 1 ` `, ` ` 4 ` `]]) ` ` print ` ` (` `" Not equal: "` `, b, ` `" "` `) `   ` a ` ` = ` ` geek.array ([` ` 4 ` `, ` ` 2 ` `]) ` ` b ` ` = ` ` geek.array ([` ` 6 ` `, ` ` 2 ` `]) ` ` `  ` print ` ` (` ` "Is a lesser than b:" ` `, a & lt; b) `

Output:

` Not equal: [False True] Not equal: [[False True] [False True]] Is a lesser than b: [True False]] `

Code 2:

` `

` # Python program illustrating # numpy.less () method   import numpy as geek     # Here we compare complex values ​​with int a = geek.array ([ 1j , 2 ]) b = geek.array ([ 1 , 2 ])    # indicates that 1j is less than 1 print ( "Comparing complex with int:" , a & lt; b)   # indicates that 1j is less than 1 d  = geek.less (a, b) print ( "Comparing complex with int .less (): " , d) `

` `

Output:

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

Code 3:

 ` # Python program illustrating ` ` # numpy.less () method `   ` import ` ` numpy as geek ` ` `  ` # Here we compare Float with int values ​​` ` a ` ` = ` ` geek.array ([` ` 1.1 ` `, ` ` 1 ` `]) ` ` b ` ` = ` ` geek.array ([` ` 1 ` `, ` ` 2 ` `]) ` ` `  ` # indicates that 1.1 is greater than 1 ` ` print ` ` (` ` "Comparing float with int:" ` `, a & lt; b) `   ` # indicates that 1.1 is greater than 1 ` ` d ` ` = ` ` geek.less (a, b) ` ` print ` ` (` ` "Comparing float with int using .less (): "` `, d) `

Output:

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