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 method.
