Python 从句子字符串中提取每个单词的第一个字符

我需要做一个代码，当你输入一个文本时，它会从你放置的句子中的每个单词中提取第一个字母

---

例如，对于示例字符串

“我喜欢弹吉他、钢琴和鼓”

，它应该打印

“Iltpgapad”

尝试以下内容：

line = "I like to play guitar and piano and drums"
words = line.split()
letters = [word[0] for word in words]
print "".join(letters)

---

此代码段与Python 3.x兼容：

print(''.join([x[0] for x in raw_input("Enter text:").split()]))

请阅读：

line = "I like to play guitar and piano and drums"
letters = ""
words = line.split()
for word in words:
    letters = letters + word[0]
print(" ".join(letters).upper())
