```python
def a_b(a:chr,b:chr):
return a.lower()==b.lower()#这里改不改都行
def wd(a:str,b:str):
na=len(a)
nb=len(b)
count=0
first=-1
for i in range(nb):
if a_b(a[0],b[i]) and(i==0 or not('a'<=b[i-1]<='z' or 'A'<=b[i-1]<='Z')):#这里加上判断，即 b[i] 前面一个字符不是字母
j=1
k=i+1
while j<na and k<nb and a_b(a[j],b[k]):
j+=1
k+=1
if j==na and ((k<nb and not('a'<=b[k]<='z' or 'A'<=b[k]<='Z')) or (k==nb)):
count+=1
if count==1:
first=i
if count==0:
print(first)
else:
print(count,first)
aa=input()
bb=input()
wd(aa,bb)
```
其实本题用 Python 并不需要写这么复杂：
```python
word,passage=input().lower(),' '+input().lower()+' '
l=passage.split()
num=l.count(word)
if num==0:
print(-1)
else:
ind=passage.index(' '+word+' ')
print(num,ind)
```

@[Terrible](/user/195942) 哦哦对，脑子一时间反应不过来了，去上了个厕所，突然就想到是不是前后空格的问题，我只考虑了后边，python代码其实还是能很短的，受益匪浅
