[英]Combine tuple and list into list-of-lists
I'm very new to programming and trying to combine a list and tuple into a new list: 我对编程非常陌生,并尝试将一个列表和元组合并到一个新列表中:
I'd be very grateful for a simple solution and also a brief explanation why my attempt only returns a value for cloth (I entered range 0:5 but it seems just to return element 4, cloth and its price) 我将非常感谢您提供一个简单的解决方案,并简要说明了为什么我的尝试仅返回布的值(我输入的范围是0:5,但似乎只是返回元素4,布及其价格)
import random
goods = ("Silk", "Gems", "Wool", "Hide", "Cloth", "Iron")
def set_prices ():
price_s = random.randrange(180,300)
price_g = random.randrange(250,800)
price_w = random.randrange(1,5)
price_h = random.randrange(5,18)
price_c = random.randrange(20,50)
price_i = random.randrange(50,150)
prices = [price_s,price_g,price_w,price_h,price_c,price_i]
for n in range (0,5):
offer = [(goods[n],prices[n])]
print (offer)
set_prices()
The problem is that range(0,5)
will only produce 0,1,2,3,4
, as the 5
is excluded. 问题在于
range(0,5)
仅会产生0,1,2,3,4
,因为排除了5
。 An easy solution is to use range(len(goods))
, to produce a range with the same number of values of goods: 一个简单的解决方案是使用
range(len(goods))
,以产生具有相同数量商品价值的范围:
for n in range(len(goods)):
...
Alternatively, you could use zip
to iterate through both lists simultaneously: 另外,您可以使用
zip
来同时遍历两个列表:
for offer in zip(goods,prices):
print(offer)
This produces output as a tuple: 这产生的输出为元组:
('Silk', 276)
('Gems', 486)
...
but can be converted to a list with list(offer)
: 但是可以使用
list(offer)
转换为列表:
['Silk', 188]
['Gems', 620]
['Wool', 2]
['Hide', 14]
['Cloth', 38]
['Iron', 130]
