[처음 시작하는 파이썬] ch5. 연습문제

#  5.1
#  m으로 시작하는 단어를 대문자로 만들어보자.

song = """When an eel grabs your arm,
And it causes great harm,
That's - a moray!"""

 

 

THINK1.

print(song.replace('m', 'M'))

=>When an eel grabs your arM,
And it causes great harM,
That's - a Moray!

 

아닌듯..

 

THINK2.

moray = (song[-6:])
moray = (moray.capitalize())

print(moray)

=> Moray!

 

모레이 슬라이스해서 어떻게 해보려다가 문득 생각이 나서..

 

THINK3.

split()을 써본다.

song_list = (song.split(' '))
print(song_list)

song_list[-1] = (song_list[-1].capitalize())
print(song_list)

print(' '.join(song_list))

['When', 'an', 'eel', 'grabs', 'your', 'arm,', 'And', 'it', 'causes', 'great', 'harm,', "That's", '-', 'a', 'moray!']
['When', 'an', 'eel', 'grabs', 'your', 'arm,', 'And', 'it', 'causes', 'great', 'harm,', "That's", '-', 'a', 'Moray!']

When an eel grabs your arm, And it causes great harm, That's - a Moray!

성공!.!

SyntaxError: invalid syntax. Perhaps you forgot a comma?

엥..? 왜 안돼..
