## Overview
The **`numpy.eye()` function** in Python is used to return a two-dimensional array with ones (1) on the diagonal and zeros (0) elsewhere.

## Syntax
```
numpy.eye(N, M=None, k=0, dtype=<class 'float'>, order='C', *, like=None)
```
## Parameters
The `numpy.eye()` function takes the following parameter values:
* **`N`**: This represents the number of rows we want in the output array.
* **`M`**: This represents the number of columns we want in the output array. This is optional.
* **`k`**: This represents the index of the diagonal. `0` is the default value and the main diagonal. This is optional.
* **`dtype`**: This represents the data type of array to be returned. This is optional.
* **`order`**: This represents whether the output should be stored in `C` or `F` order in memory. This is optional.
* **`like`**: This is the array prototype or `array_like` object.

## Return value
The `numpy.eye()` function returns a type of array where all the elements are equal to `0`, except for the $k^{th}$ diagonal, whose values are equal to `1`.

## Example 1



import numpy as np

# An array with 3 rows with with the ones starting at the index i.e fron the second column
myarray = np.eye(3, k=1)

print(myarray)

import numpy as np

# An array with 2 rows and integer data type
myarray = np.eye(2, dtype=int)

print(myarray)

## Explanation
* **Line 1**: We import the `numpy` module.
* **Line 4**: We use the `numpy.eye()` function to create an array with `3` rows and the ones should start on  index `1` of the array. The output is stored in a variable `myarray`.
* **Line 6**:  We print the variable `myarray`.

## Example 2



## Explanation
* **Line 1**: We import the `numpy` module.
* **Line 4**: We use the `numpy.eye()` function to create an array with `2` rows. The data type of the array should be integer. The output is stored in a variable `myarray`.
* **Line 6**: We print the variable `myarray`.
