# How to find the maximum and minimum value in NumPy 1d-array?

Let’s see the various ways to find the maximum and minimum value in NumPy 1d-array.

Method 1: Using numpy.amax() and numpy.amin() functions of NumPy library.

• numpy.amax(): This function returns maximum of an array or maximum along axis(if mentioned).
• numpy.amin(): This function returns minimum of an array or minimum along axis(if mentioned).

Example:

## Python3

 `# import library ` `import` `numpy as np ` ` `  `# create a numpy 1d-array ` `array ``=` `np.array([``1``, ``2``, ``3``,  ` `                  ``0``, ``-``1``, ``-``2``]) ` ` `  `# find max element in an array ` `max_ele ``=` `np.amax(array) ` ` `  `# find man element in an array ` `min_ele ``=` `np.amin(array) ` ` `  ` `  `# show the outputs ` `print``(``"Given Array:"``, array) ` ` `  `print``(``"Max Element:"``, max_ele) ` ` `  `print``(``"Min Element:"``, min_ele)`

Output:

```Given Array: [ 1  2  3  0 -1 -2]
Max Element: 3
Min Element: -2
```

Method 2: Using numpy.argmax() and numpy.argmin() function of NumPy library.

• numpy.argmax(): This function returns indices of the max element of the array in a particular axis(if mentioned).
• numpy.argmin(): This function returns indices of the min element of the array in a particular axis(if mentioned).

Example:

## Python3

 `# import library ` `import` `numpy as np ` ` `  `# create a numpy 1d-array ` `array ``=` `np.array([``1``, ``2``, ``3``, ` `                  ``0``, ``-``1``, ``-``2``]) ` ` `  `# find index of max element ` `# in an array ` `max_ele_index ``=` `np.argmax(array) ` ` `  `# find max element in an array ` `max_ele ``=` `array[max_ele_index] ` ` `  `# find index of min element ` `# in an array ` `min_ele_index ``=` `np.argmin(array) ` ` `  `# find min element in an array ` `min_ele ``=` `array[min_ele_index] ` ` `  `# show the outputs ` `print``(``"Given Array:"``, array) ` ` `  `print``(``"Max Element:"``, max_ele) ` ` `  `print``(``"Min Element:"``, min_ele)`

Output:

```Given Array: [ 1  2  3  0 -1 -2]
Max Element: 3
Min Element: -2
```
