I would like to get some code review for my recursive implementation of python flatten array method. Write a piece of functioning code that will flatten an array of arbitrarily nested arrays of integers into a flat array of integers. e.g. [[1,2,[3]],4] -> [1,2,3,4]. I'm particularly...

Any suggestions are highly appreciated. I am a beginner in Python. upper_bound = 50 def remove_non_primes(list_of_ints, prime_to_check_against): only_primes = list() for i in range(len(list_of_ints)): if list_of_ints[i] % prime_to_check_against != 0: only_primes.appe...
