将字母在错误位置的单词分类

Question

所以，我正在寻找在错误位置有字母的单词，我想我需要一种方法来表示一个“幽灵”字符，让任何字母都可以去那里。

 import sys
#list of words that are available
list1 = [
"hello",
"saryt",
"artsy"
]

c = 0
#letters that can't be used
deadletters = ("h","e","l","l","o")

#sorts out words with dead letters
for word in list1:
if not any(map(lambda x: x in word, deadletters)):
 if "a"+""+""+""+"y" in word:
   #only lets words with "a___y" through
   print(f"found: {word}")
   c += 1
 
print(c)
sys.exit

Answer 1

list1 = [
    "hello",
    "saryt",
    "artsy",
    "ahoy"
]

#letters that can't be used
deadletters='hello'

#sorts out words with dead letters
list2 = [w for w in list1 if not(any(set(w) & set(deadletters)))]
print(list2)

#only lets words with "a___y" through
found = [w for w in list2 if (w[0] == 'a') & (w[-1] == 'y')]

print(found)
