Python: more elegant way to assert type of function input
I am a complete beginner in Python… Currently I am trying to write a function which first checks whether the inputs x and y are int or float. My guess which does the job is if (type(x) != int and type(x) != float) or (type(y) != int and type(y) != float): However, this seems quite clumsy / inefficient t…

Counting the number of triplets forming GP series in python
The problem statement is: You are given an array and you need to find number of triplets of indices(i,j,k) such that the elements at those indices are in geometric progression for a given common ratio, r and i<j<k. For example, arr=[1,4,16,64]. If r=4, we have [1,4,16] and [4,16,64] at indices (0,1,2) a…
