Hello, Does python have andmap and ormap:
andmap((lambda t: boolean(t)),L) gives True if boolean(t) is True for all t in L and False otherwise? And ormap((lambda t: boolean(t)),L) gives True if boolean(t) is True for some t in L and False otherwise? One can use a list comprehension like [x for x in L if not(False in map((lambda t: boolean(t)),L))] as an example of selection by andmap, and [x for x in L if (True in map((lambda t: boolean(t)),L))] as an example of selection by ormap. How does one define andmap/ormap so its first argument is a boolean procedure or lambda? def andmap(b,L): if False in map(b,L): return False else: return True def ormap(b,L): if True in map(b,L): return True else: return False Is this good enough?
