Use Python please

Write a function called find_min that takes a list of lists and returns the minimum value across all lists. Test it with the following

if __name__ == "__main__": v = [ [ 11,12,3], [6, 8, 4], [ 17, 2, 18, 14] ] print("Min of list v: {}".format(find_min(v)) ) u = [ [ 'car', 'tailor', 'ball' ], ['dress'], ['can', 'cheese', 'ring' ], \ [ 'rain', 'snow', 'sun' ] ] print("Min of list u: {}".format(find_min(u)) )
