 本题注意点：字符串处理技巧，另见      https://blog.youkuaiyun.com/zuocuomiao/article/details/82146577

     'a'*3可以得到'aaa'； join()可以实现字符串数组拼接成一个字符串。

import numpy as np

def toGoatLatin(S):
    """
    :type S: str
    :rtype: str
    """
    ans = []
    vowel = set('aeiouAEIOU')
    S = S.split(' ')
    for i, x in enumerate(S):
        if x[0] not in vowel:
            x = x[1:]+x[0]
        x += 'ma'
        x += 'a' * (i+1)
        ans.append(x)
    return ' '.join(word for word in ans).strip()

# samples:
S = "I speak Goat Latin"
print(toGoatLatin(S))
S = "The quick brown fox jumped over the lazy dog"
print(toGoatLatin(S))
