In Python, you can find the cumulative sum of a list or array based on a condition using various libraries like NumPy or by using pure Python. This tutorial will walk you through both methods with code examples.
To find the cumulative sum based on a condition using pure Python, you can use a for loop and a list to store the cumulative sum values. Here's a step-by-step guide with an example:
Here's the complete code and its output:
Output:
NumPy is a powerful library for numerical operations in Python. It provides an efficient way to work with arrays and perform cumulative operations. To find the cumulative sum based on a condition using NumPy, follow these steps:
If you haven't already installed NumPy, you can do so using pip:
Then, import NumPy in your Python script:
Here's the complete code and its output:
Output:
NumPy's np.cumsum function efficiently calculates the cumulative sum, taking into account the elements that meet the specified condition.
This tutorial covers two methods to find the cumulative sum based on a condition in Python, using pure Python and the NumPy library. You can choose the method that best suits your needs and the complexity of your data.
