The key is to 'vectorize' the function. Here is an example: def myfunc(a,b): if (a>b): return a. else: return b. vecfunc = np.vectorize(myfunc) result=vecfunc([[1,2,3],[5,6,9]],[7,4,5]) print(result) Output:
Dec 17, 2019 · If you want to pass in a List (Array from other languages) you'd do something like this: def someFunc(myList = [], *args): for x in myList: print x Then you can call it with this: items = [1,2,3,4,5] someFunc(items) You need to define named arguments before variable arguments, and variable arguments before keyword arguments.
