循环和显示图片的问题

Question

我正在做一个ASL（美国手语）程序，用户输入一封信，作为回报，他们会得到正确签名的图片。我可以一次只写一个字母，但我希望得到完整的单词。 这是我正在处理的循环：

from images import Image
print('*** Welcome to the ASL Translator ***')
print('Press ENTER to quit at any time')
letter = input(str('What letter/word would you like to translate (A-Z): '))

#breaking the user input into letters
seperate = list(letter)

i = 0
for i in range(len(seperate)):
    if seperate[0] == 'A' or seperate[0] == 'a':
        image = Image('A.gif')
        image.draw()
        i += 1
    if seperate[1] == 'B' or seperate[1] =='b':
        image = Image('B.gif')
        image.draw()
        i += 1
    if seperate[2] == 'C' or seperate[2] == 'c':
        image = Image('C.gif')
        image.draw()
        i += 1

这就是我的作品，一次只能写一封信

if letter == 'A' or letter == 'a':
    image = Image('A.gif')
    image.draw()
    i += 1
elif letter == 'B' or letter == 'b':
    image = Image('B.gif')
    image.draw()
    i+= 1
elif letter == 'C' or letter == 'c':
    image = Image('C.gif')
    image.draw()
    i+= 1
elif letter == 'D' or letter == 'd':
    image = Image('D.gif')
    image.draw()
elif letter == 'E' or letter == 'e':
    image = Image('E.gif')
    image.draw()
elif letter == 'F' or letter == 'f':
    image = Image('F.gif')
    image.draw()
elif letter == 'G' or letter == 'g':
    image = Image('G.gif')
    image.draw()
elif letter == 'H' or letter == 'h':
    image = Image('H.gif')
    image.draw()

。 . . . 等等，一直到z

如果您能帮助我，请提前感谢！：）

试试这个：

from images import Image
print('*** Welcome to the ASL Translator ***')
print('Press ENTER to quit at any time')
letter = input(str('What letter/word would you like to translate (A-Z): '))

#breaking the user input into letters
seperate = list(letter)

for i in seperate:
    i=i.upper()
    image = Image(str(i)+'.gif')   
    image.draw()
