Python：将列表转换成字典

Question

I have a list stored in a variable and I am trying to convert this list into a dictionary with with dictionary keys corresponding to their respective list index. The point is to create a list of images and rects to blit (which isn't shown here but I've tested that that portion of the code does indeed work). Here's the code:

hand = ['Lakers_01.png', 'Lakers_02.png', 'Lakers_03.png', 'Lakers_04.png']
tempHand = hand
finTempHand = {}
newTempHand = ["pygame.image.load("+tempHand+")" for t in tempHand]
print(newTempHand)
for i in range(0,len(newTempHand)):
    finTempHand[i] = newTempHand[i]

and I am getting this error:

newTempHand = ["pygame.image.load("+tempHand+")" for t in tempHand]
TypeError: must be str, not list

Thank you in advance

Answer 1

You can accomplish that using dictionary comprehension.

hand = ['Lakers_01.png', 'Lakers_02.png', 'Lakers_03.png', 'Lakers_04.png']
finTempHand = {
    i: "pygame.image.load({})".format(x) 
        for i, x in enumerate(hand)
}

Answer 2

First of all you are using the wrong variable

newTempHand = ["pygame.image.load("+tempHand+")" for t in tempHand]

should be

newTempHand = ["pygame.image.load("+t+")" for t in tempHand]

Second you can use a dict comprehension and also remove that 0 from the range

Full code:

    hand = ['Lakers_01.png', 'Lakers_02.png', 'Lakers_03.png', 'Lakers_04.png']

    finTempHand = {
        i: 'pygame.image.load({})'.format(current)
        for index, current in enumerate(hand)
    }
