从字符串中提取每个单词的第一个字符

Question

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"I like to play guitar and piano and drums"，它应该打印"Iltpgapad"

Answer 1

试试这样的：

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

Answer 2

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())

Answer 3

此代码段与Python3.x兼容：

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