# How to Calculate Derivative in Python

This tutorial will introduce the methods to calculate the derivate of a function in Python.

## Derivative With the SymPy Library in Python

The SymPy library is known as the `Python Symbolic library`

. It can be used to perform complex mathematical operations like derivatives on functions in Python. The `diff()`

function inside the SymPy library can be used to calculate the derivative of a function. We can specify the variable with which we want to calculate the derivative with the `Symbol()`

function in Python. See the following code example.

```
from sympy import *
import numpy as np
x = Symbol("x")
y = x ** 2 + 1
yprime = y.diff(x)
print(yprime)
```

Output:

```
2*x
```

In the above code, we calculated the derivative of the function `x^2 + 1`

with the `diff()`

function of the SymPy library in Python. We specified the symbol to be `x`

with the `Symbol()`

function and calculated the derivative with respect to the symbol `x`

.
