numbers = int(raw_input("How many numbers would you like to use?")

numbers_list = []

for input in range(numbers):
    new_number = float(raw_input("Enter your numbers.")
    numbers_list.append(new_number)

if math == "+":
    print sum(new_number)

if math == "*":
    import numpy
    product = numpy.product(numbers_list)
    print (product)

正确地缩进代码

math = raw_input("Addition + or multiplication *.")

numbers = int(raw_input("How many numbers would you like to use?"))

numbers_list = []

for input in range(numbers):
    new_number = float(raw_input("Enter your numbers."))
    numbers_list.append(new_number)

if math == "+":
    print sum(new_number) # throws error TypeError: 'float' object is not iterable, so it should be
    #print sum(numbers_list)

if math == "*": 
    import numpy 
    product = numpy.product(numbers_list)
    print (product)
