Sometimes, we want to find the cumulative sum of numbers in a list with Python.

In this article, we’ll look at how to find the cumulative sum of numbers in a list with Python.

### How to find the cumulative sum of numbers in a list with Python?

To find the cumulative sum of numbers in a list with Python, we can use the numpy `cumsum`

method.

For instance, we write

```
import numpy as np
a = [4, 6, 12]
s = np.cumsum(a)
```

to call `np.cumsum`

with list `a`

to return the cumulative sum of the list items as a numpy array.

### Conclusion

To find the cumulative sum of numbers in a list with Python, we can use the numpy `cumsum`
