I need to write a program that the user input numbers and stops when the user enter 0, them it should see which number is a prime number and sum only the prime numbers.



I wrote it but it counts even if the number isn't a prime.

First of all, you are putting the definition inside the while loop, this will not disrupt your code, but make it significantly slow.
Second, you are using statements like if False, that will ALWAYS return False and the code wont run



So, instead of using if False try if not prime(num), then put an else statement for the other half. You don't even need the sum_of_primes = 0 +sum_of_primes, you can just remove that so you can finally replace the if-else with:



if prime(num):

    sum_of_primes = sum_of_primes + num

            Dulmage-Mendelsohn matrix decomposition in Python

            Image
            0 Matlab has a function called dmperm that computes the so-called Dulmage–Mendelsohn decomposition of a n x n matrix. From wikipedia, the Dulmage–Mendelsohn is a partition of the vertices of a bipartite graph into subsets, with the property that two adjacent vertices belong to the same subset if and only if they are paired with each other in a perfect matching of the graph. Looking both on scipy and numpy, I could not find this function, nor some similar version. Is it possible to implement it using basic linear algebra operations? Any idea if this is implemented in some Python package? python matlab linear-algebra graph-theory matrix-decomposition share | improve this question
