Given numpy array, the task is to find elements within some specific range. Let’s discuss some ways to do the task.

Method #1: Using `np.where()`

 `# python code to demonstrate``# finding elements in range``# in numpy array``import` `numpy as np`` ` `ini_array ``=` `np.array([``1``, ``2``, ``3``, ``45``, ``4``, ``7``, ``810``, ``9``, ``6``])`` ` `# printing initial array``print``(``"initial_array : "``, ``str``(ini_array));`` ` `# find elements in range 6 to 10``result ``=` `np.where(np.logical_and(ini_array>``=` `6``, ini_array<``=` `10``))`` ` `# printing result``print``(``"resultant_array : "``, result)`
Output:
```initial_array :  [  1   2   3  45   4   7 810   9   6]
resultant_array :  (array([5, 7, 8]),)
```

Method #2: Using `numpy.searchsorted()`

 `# Python code to demonstrate``# finding elements in range``# in numpy array`` ` `import` `numpy as np`` ` `ini_array ``=` `np.array([``1``, ``2``, ``3``, ``45``, ``4``, ``7``, ``9``, ``6``])`` ` `# printing initial array``print``(``"initial_array : "``, ``str``(ini_array));`` ` ` ` `# find elements in range 6 to 10``start ``=` `np.searchsorted(ini_array, ``6``, ``'left'``)``end ``=` `np.searchsorted(ini_array, ``10``, ``'right'``)``result ``=` `np.arange(start, end)`` ` `# printing result``print``(``"resultant_array : "``, result)`
Output:
```initial_array :  [ 1  2  3 45  4  7  9  6]
resultant_array :  [5 6 7]
```

Method #3: Using *

 `# Python code to demonstrate``# finding elements in range``# in numpy array`` ` `import` `numpy as np`` ` `ini_array ``=` `np.array([``1``, ``2``, ``3``, ``45``, ``4``, ``7``, ``9``, ``6``])`` ` `# printing initial array``print``(``"initial_array : "``, ``str``(ini_array));`` ` ` ` `# find elements in range 6 to 10``result ``=` `ini_array[(ini_array>``6``)``*``(ini_array<``10``)]`` ` `# printing result``print``(``"resultant_array : "``, result)`
Output:
```initial_array :  [ 1  2  3 45  4  7  9  6]
resultant_array :  [7 9]
```
