Why am I getting this list indices error?-CodePudding

Sorry, I'm new to programming so excuse me if my question is lackluster. I want to load these images through the use of a list and a for loop but I keep getting this list error where it says the list indices must be integers or slices. How can I fix this?

code:

Images = ['K2', 'G2', 'S2', 'N2', 'L2', 'R2', 'B2', 'P2']

p = []
for n in Images:
    p.append(pygame.image.load(os.path.join('Assets', 'Pieces (set 1)', Images[n]   '.png')))

error:

p.append(pygame.image.load(os.path.join('Assets', 'Pieces (set 1)', Images[n]   '.png')))
TypeError: list indices must be integers or slices, not str

CodePudding user response：

See for Statements. Either

for i in range(len(Images)):
    p.append(pygame.image.load(os.path.join('Assets', 'Pieces (set 1)', Images[i]   '.png')))

for name in Images:
    p.append(pygame.image.load(os.path.join('Assets', 'Pieces (set 1)', name   '.png')))

Consider what values n take here: for n in Images:. n will loop through the elements in Images, thus n is of type str. You cannot use a string as an index to a list Images[n]. You probably meant to construct the loop like this: for n in range(len(Images)). Then n will be integers from 0 to len(Images) - 1.
