如何找到一个句子甚至有相反的蟒蛇那些单词

我想获得找出所有在同一个句子已经扭转话里话。如何过，代码我只找到这个词的首次出现。在我的一句“我要去吃饭MA和TAE也将走”，我应该得到时许输出（MA反转字），吃（TAE是反转的话）。我am..how可以修改这个代码来获取所有已扭转的话在它即两个上午，吃的话我只得到。

input_str='i am going to eat ma and tae will also go'
word=input_str.split()
def isReverseEqual(s1, s2): 

    # If both the strings differ in length 
    if len(s1) != len(s2): 
        return False

    l = len(s1) 

    for i in range(l): 

        # In case of any character mismatch 
        if s1[i] != s2[l-i-1]: 
            return False
    return True
def getWord(str, n): 
    reverse=[]
    # Check every string 
    for i in range(n-1): 

        # Pair with every other string 
        # appearing after the current string 
        for j in range(i+1, n): 

            # If first string is equal to the 
            # reverse of the second string 
            if (isReverseEqual(str[i], str[j])): 
                reverse.append(str[i])
                return reverse 


    # No such string exists 
    return "-1"
print(getWord(word, len(word))) 

输出：[ 'AM'， '吃']是我们所期望的。
