I’m calculating the sum of my array values using the sum() function and it is giving the correct result. This task is a part of my assignment and I’m not allowed to use the sum() function. Can someone help me calculate the sum of array values using different methods except sum()?
The above code is working fine but problem is that it is using the sum() function and I want a similar functionality code but without using the sum() function.
To calculate the sum of all values in a NumPy array, you can use the
cumsum() function, which calculates the cumulative sum of the array’s elements. Here is an example code that achieves this:
- The code calculates the cumulative sum of the input array using
cumsum() and returns an array of the same size where each element is the sum of all the elements before it.
- Since you want to calculate the complete sum of all values in the array, the code accesses the last element in the resulting array using
[-1] to get the total sum.
