我正在执行anti_元音功能，该功能基本上从输入中取出所有元音，并且那里有一些错误。下面是我的代码]
def anti_vowel(text):
vowel="aeiouAEIOU"
for i in range(len(text)-1):
for h in range(len(vowel)-1):
if text[i]==vowel[h]:
text=text.replace(text[i],"")
return text
print anti_vowel("HELLO")
如果输入“ HELLO”，将成功打印“ HLL”。但是如果我将输入更改为“ Hey look Words！”，它显示错误IndexError：超出范围的字符串索引。如果有人可以帮助我解决此问题，我非常感谢。
您遇到的问题是，.replace()替换了文本中出现的所有实例。因此，在调用.replace("o","")时，您要替换句子中的所有“ o”，这会使句子更短。因此发生了IndexError。
看看这个：
def anti_vowel(text):
vowel="aeiouAEIOU"
for i in range(len(text)-1):
for h in range(len(vowel)-1):
print(i,h, text)
if text[i]==vowel[h]:
text=text.replace(text[i],"")
return text
print(anti_vowel("Hey look Words!"))
输出：

即IndexError出现的时间。如您所见，尝试替换第一个'o'时，所有'o'都被替换。
我在另一个SO-post上标记了您的问题，其中显示了如何成功进行此操作。
