将两个列表与嵌套的for循环串联在一起

Question

I want to create a list of string elements that is a deck of cards.

I created two lists of strings (1-Ace and suites). I want to use nested for loops to do this, and include a word in-between the two (" of "). I did this quickly and easily when printing everything, but when I went to append to another list (deck) I've run into problems creating the string variable that I want.

EDIT: I'm receiving the following error: "inconsistent use of tabs and indentation".
I'm currently using notepad++, but I'd gotten the same error earlier when I was using the IDLE.

nums = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace"]
suite = ["Diamonds", "Hearts", "Clubs", "Spades"]
deck = []

for element in nums:
    for suit in suite:
        card = "%s of %s" % (element, suit)
        deck.append(card)
        print (deck)

My goal is to have a list of strings similar to this ... ["1 of hearts", "Ace of spades"]...

Thanks!

The error points to improper mixing of tabs and spaces. Most text editors offer an option 'replace tabs by spaces' or something similar. Or, if you plan to stick with Python, I strongly recommend using a serious IDE like PyCharm (my favourite) or Eclipse/PyDev .

Other than that, there is nothing wrong with the code you posted. itertools.product is your friend if you want to ease the task though (and avoid indentation altogether):

from itertools import product

deck = [' of '.join(p) for p in product(nums, suite)]

Or even shorter with the help of map :

deck = map(' of '.join, product(nums, suite))
