# Find cube root of a number in Python

In this tutorial, we are going to learn how to find the cube root of a number in Python.

## How to find the cube root of a number in Python

Let us understand with an example.
Suppose a number stored in a variable.

`a=125`

We can find the cube root of 125 using a trick :

```a=125
print(a**(1/3))```

As we know that the cube root of 125 is 5. So it will return 5.
Note:- This trick will not work in case of negative integers

`5.0`

If we want to find the cube root of a negative integer. Then we have to make some changes in the above trick.

```a=-125
print(-(-a)**(1/3))```
`-5.0`

### Function to find cube root using Python:

We can define a function for cube root. When a user inputs a number for cube root, it will automatically return the cube root of the number.

```def cube_root(x):
return x**(1/3)
print(cube_root(27))```

As we can see, I have defined a function cube root. And I have called the same function with input 27. So it will return the cube root of 27.

`3.0`

Hello
Thanks for your good trick
But this method does not work correctly on some numbers
For example: number 185193

If I try this with 64, then I get 3 and not 4. Any idea why?

3. Awharitoma kenneth says:

Cube Root
number = float(input( “Enter a number please? “)
cube_root = number**(1/3)
print(cube_root)

4. Muhammad Hamza says:

for some digits like 636.it doesn’t give the exact answer instead it give in terms of .99999999
