This tutorial will introduce the methods to calculate the absolute value in Python.

## Calculate Absolute Value With the `abs()` Function in Python

The absolute value of a number is calculated by taking the square root of its square. The `abs()` function is a built-in function that can be used to find the absolute value of a number in Python. The following code example shows us how we can use the `abs()` function to find the absolute value in Python.

``````import numpy as np

x1 = np.array([-1, -2])

print(abs(x1))
``````

Output:

``````[1, 2]
``````

In the above code, We calculated the absolute value of the variable `x1` with the `abs()` function in Python.

## Calculate Absolute Value With the `numpy.absolute()` Function

We can also use the `numpy.absolute()` function inside the `NumPy` package to calculate the absolute value. See the following code example.

``````import numpy as np

x1 = np.array([-1, -2])

print(np.absolute(x1))
``````

Output:

``````[1, 2]
``````

## Calculate Absolute Value With the `numpy.abs()` Function

There is also a `abs()` function inside the `NumPy` package just like the `abs()` function in core-python that can be used to calculate the absolute value. The following code example shows us how we can calculate the absolute value of a numpy array with the `numpy.abs()` function in Python.

``````import numpy as np

x1 = np.array([-1, -2])

print(np.abs(x1))
``````

Output:

``````[1, 2]
``````

All the functions discussed above are exactly the same and do the same thing. There are no differences in any of the methods discussed above. We can use any of the above-mentioned methods to find the absolute value of a number in Python.
