循环和显示图片的问题

Question

我正在使用用户输入信函的ASL（美国手语）程序，并且作为回报他们得到正确签名的图片。我可以一次处理一封信，但我希望得到完整的文字。 继承人的循环IM工作：

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 

这是我有一次为一个字母的作品。

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() 

。 。 。 。等到一切z

在此先感谢，如果你能帮助我！ :)

Answer 1

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): ')) 


for ltr in letter.upper(): 
    if os.path.exists("%s.gif"%ltr): 
     image = Image("%s.gif"%ltr) 
     image.draw() 

我觉得应该工作

Answer 2

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()
